Detection of peritoneal metastases


The peritoneum is the largest and most complexly arranged serous membrane in the body. The potential peritoneal spaces, the peritoneal reflections forming peritoneal ligaments, mesenteries, omenta, and the natural flow of peritoneal fluid determine the route of spread of intraperitoneal fluid and consequently disease spread within the abdominal cavity. The peritoneal ligaments, mesenteries, and omenta also serve as boundaries and conduits for disease spread. Peritoneal metastases spread in four ways:

  • Direct spread along peritoneal ligaments, mesenteries and omenta to non-contiguous organs

  • Intraperitoneal seeding via ascitic fluid

  • Lymphatic extension

  • Embolic haematogenous spread.

Before the introduction of cross-sectional imaging, the peritoneum and its reflections could only be imaged with difficulty, often requiring invasive techniques. Computed tomography and to a lesser extent sonography and MR imaging allow us to examine the complex anatomy of the peritoneal cavity accurately, which is the key to understanding the spread of peritoneal metastases. This article reviews the detection of peritoneal metastases.


The peritoneal cavity is the potential space between the visceral and parietal layers of the peritoneum. The parietal peritoneum is reflected over the peritoneal organs to form a series of supporting ligaments, mesenteries and omenta (Fig. 1). These peritoneal reflections act as a natural pathway for the dissemination of intra-abdominal disease within the peritoneum, but also allow extension of disease from the retroperitoneum to structures enveloped by peritoneum, via the subperitoneal space[1].

Metastatic disease is the most common malignant process involving the peritoneum. Metastases are usually from intra-abdominal primary neoplasms, such as carcinoma of the stomach, colon, ovary and pancreas, or from intraabdominal lymphoma.

Prior to the advent of CT, peritoneal metastases were not radiographically detectable until late in the disease, when they displaced adjacent organs, caused intestinal obstruction, or produced radiological signs due to massive ascites on plain films. CT can identify peritoneal metastases as small as a few millimetres in size and also identify very small volumes of ascites. This information is essential in staging tumours, assessing resectability, monitoring response, and identifying recurrence.

The imaging appearances of metastatic peritoneal disease are in part determined by the tumour type itself, but predominantly by the mode of peritoneal dissemination.

Imaging Techniques

Computed tomography

CT is considered the best imaging procedure for the evaluation of patients with known or suspected peritoneal metastases. The use of intraperitoneal positive contrast and pneumoperitoneum with CT has been suggested to improve the detection of small peritoneal metastases but these techniques do not routinely opacify all the peritoneal recesses[24]. These methods are more interventional and time consuming and consequently are not widely used.

MR Imaging

Recent reports describe the use of MR imaging in identifying peritoneal implants[5,6]. MR imaging of the peritoneum has been most successfully achieved using fat saturated T1-weighted sequences following intravenous gadolinium[7]. The inferior spatial resolution, the problems of motion artefact related to respiration and bowel peristalsis, and the lack of an effective bowel opacification agent makes MR imaging a generally less accurate test than CT for the identification of peritoneal metastases. However a recent report from the Radiological Diagnostic Oncology Group[8] reviewed the performance of ultrasound, MR imaging, and CT for diagnosing and staging ovarian cancer. They found in a group of 280 patients that CT and MR imaging had similar accuracy for staging advanced ovarian cancer. Both were much more accurate than ultrasound.

This study used state-of-the-art MR techniques with phased array body coils, breath-hold sequences which included T1-weighted images with fat saturation before and after intravenous gadolinium chelate.


Ultrasound will demonstrate superficial peritoneal and omental metastases as small as 2 to 3 mm in the presence of ascites. However, centrally located deposits, for example in the small mesentery, will not be visualized because of the acoustic impedance of bowel gas and fat[9, 10]. Ultrasound is useful for image-guided aspiration/drainage of ascites and the biopsy of superficial peritoneal deposits.

Barium studies

Barium studies provide only indirect signs of peritoneal and mesenteric disease and thus are not used as the first line of investigation. The typical features of mesenteric or omental infiltration by metastases include: mass effect on adjacent bowel; nodularity, spiculation or tethering of adjacent mucosal folds or haustra; sacculation of the uninvolved contralateral border; or circumferential narrowing of the bowel lumen. These changes most frequently occur with contiguous involvement of the transverse colon or stomach. Barium studies will occasionally reveal abnormalities related to peritoneal metastases not clearly demonstrated on CT.


Scintigraphy has also been used to identify peritoneal metastases but is not very sensitive or specific and needs CT for anatomical location[11].

Modes of Spread and Imaging Appearances

Metastases spread throughout the peritoneum in four ways:

  • directly along peritoneal ligaments, mesenteries and omenta to non-contiguous structures;

  • intraperitoneal seeding via the flow of ascitic fluid;

  • lymphatic extension;

  • embolic haematogenous spread[12].

Direct spread

Direct invasion from primary tumours to noncontiguous organs occurs along the peritoneal reflections (Fig. 1b). These include:

  • Eight ligaments — the right and left coronary, falciform, hepatoduodenal, duodenocolic, gastros-plenic, splenorenal, and phrenicocolic ligaments;

  • Four mesenteries — the small bowel mesentery, the transverse mesocolon, the sigmoid meso-colon, and the mesoappendix;

  • Two omenta — the lesser and greater omentum[12, 13]. Spread along these peritoneal reflections is commonly seen with malignant neoplasms of the stomach, colon, pancreas and ovary.

CT appearances

Carcinoma of the stomach often spreads directly into the left lobe of the liver via the lesser omentum, extending between the lesser curvature of the stomach and the liver (Fig. 2a)[14]. CT shows loss of the fat plane between these two organs[15]. Direct spread from retroperitoneal tumours, such as carcinoma of the pancreas, into the liver can occur along the hepatoduodenal ligament, which is the free edge of the lesser omentum, extending from the junction of the first and second parts of the duodenum to the porta hepatis[16, 17]. Biliary and hepatic malignancies can also spread in the reverse direction to the stomach and pancreas via the lesser omentum and hepatoduodenal ligaments. On CT these masses are often hypervascular and may have low attenuation centrally due to central necrosis[18, 19].

Figure 2

(a) Axial post contrast CT scan in a 59-year-old male with gastric cancer showing extension of gastric cancer into the lesser omental fat. (b) Axial post contrast CT scan in a 45-year-old female with carcinoma of the pancreatic body with metastatic extension in the transverse mesocolon causing bowel obstruction.

Neoplasms of the colon, stomach, and pancreas often use the transverse mesocolon and greater omentum as conduits for spread (Fig. 2b). Direct invasion is well demonstrated on CT as increased density or discrete soft tissue masses in the fat of the transverse mesocolon. The right hand margin of the transverse mesocolon is thickened as the duodenocolic ligament providing a direct route for extension of colonic cancer from the hepatic flexure to the duodenum[20.21].

The greater omentum extends from the greater curve of the stomach and suspends the transverse colon. On CT early involvement of the greater omentum produces increased density within the fat adjacent to the primary neoplasm (Fig. 3a). Subsequently, masses contiguous with the primary neoplasm may be seen extending into the greater omentum, producing ‘omental caking’, which separates the colon from the anterior abdominal wall (Fig. 3b,). Spread of metastatic disease along the left-hand margin of the greater omentum stops abruptly at the phrenicocolic ligament, extending from the splenic flexure to the diaphragm. It marks the point at which the mesenteric transverse colon becomes the extraperitoneal descending colon.

(a) Post contrast axial CT scan in a 49-year-old female with carcinoma of the ovary showing several nodular, ill defined masses in the greater omentum anteriorto the colon. Note also the ascites. (b) Axial post contrast CT scan in a 66-year-old female with adenocarcinoma of the bowel showing a bulky, ‘cake-like’, enhancing omental deposit. (c) Axial post contrast CT scan in a 65-year-old male patient with renal carcinoma showing markedly enhancing deposits within the greater omentum surrounded by ascites. Note also enhancing serosal deposits on the surface of the bowel.

In the left upper quadrant the gastrosplenic ligament, continuous with the greater omentum, extends from the greater curve of the stomach to the spleen. It can be involved by extramural spread from gastric cancer and explains the association of splenic abscess with this tumour, often seen on CT[22].

Direct involvement of the small bowel mesentery is commonly seen in carcinoid (Fig. 4), lymphoma, pancreatic, breast and colonic metastases. Spread from the retroperitoneum, via the subperitoneal space, to the small bowel is frequently seen in lymphoma. On CT, this produces soft tissue thickening within the mesenteric fat, perivascular encasement and tethering of the bowel.

Intraperitoneal seeding

Intraperitoneal fluid is constantly circulating throughout the abdomen influenced by gravity and negative intraabdominal pressure, produced beneath the diaphragm during respiration. It allows transcoelomic dissemination of malignant cells. Their deposition, fixation and growth are encouraged in particular sites due to relative stasis of ascitic fluid[23].

The most common tumours to spread in this fashion include ovarian cancer in females and malignancies of the gastrointestinal tract in males, especially cancer of the stomach, colon, and pancreas.

The sites most commonly involved by peritoneal seeding are (Fig. 1a):

  • the pelvis, especially the pouch of Douglas;

  • the right lower quadrant at the inferior junction of the small bowel mesentery;

  • the superior aspect of the sigmoid mesocolon;

  • the right paracolic gutter[23]. Spread of deposits to the right subhepatic and subphrenic spaces is also frequently seen, especially in ovarian cancer. Almost 90% of patients with ovarian cancer have peritoneal implants at post mortem and 60–70% have ascites[24, 25].

CT appearances. On CT, seeded metastases appear as nodular or plaque-like soft tissue masses in association with ascites. Intraperitoneal deposits as small as 5 mm can be identified, even in the presence of small amounts of ascites[2628]. Rounded or oval low density deposits on the surface of the liver are frequently seen on CT in ovarian cancer (Fig. 5a)[29]. These are generally of 0 5–1cm diameter located on the dorsomedial and dorsolateral parts of the right lobe of the liver and often associated with deposits in Morison’s pouch (Fig. 5a). It is presumed that these deposits infiltrate the liver capsule following their deposition on the liver surface. The parietal peritoneum may be diffusely involved producing smooth or nodular thickening (Fig. 5a) on CT that often enhances (Fig. 5c)[30]. Peritoneal calcification is also frequently seen on CT with serous cystadenocarcinoma of the ovary (Fig. 5b), carcinoid tumour, and rarely with gastric carcinoma[3133].

Note the clips from previous renal surgery. Multiple enhancing peritoneal metastases are outlined by ascites. Note also enhancing deposits in the greater omental fat.

A distinctive CT appearance is produced by pseudomyxoma peritonei, resulting from the rupture of a mucinous cystadenocarcinoma or cystadenoma of the ovary or appendix (Fig. 6a,b). The gelatinous nature of the deposits produces a mantle of low density material over the surface of the liver, causing scalloping of its margin, in association with cystic peritoneal collections (Fig. 6a). The walls of the cystic collections may contain calcification. The pressure of the gelatinous material prevents the bowel loops floating up towards the anterior abdominal wall, which may be a useful sign in differentiating pseudomyxoma peritonei from ascites (Fig. 6b)[34].

(b) The pressure of the gelatinous material prevents bowel loops floating up towards the anterior abdominal wall.

The small bowel mesentery and greater omentum are frequently involved by intraperitoneal seeding of metastases. Four patterns of involvement are described on CT: round masses, ‘cake-like’ masses (Fig. 3b), ill-defined masses, and stellate masses[35].

Irregular, ‘cake-like’ masses are seen most often with ovarian cancer[36]. Densely calcified omental ‘cake’ has been reported in metastatic serous cystadenocarcinoma[37]. The stellate pattern of mesenteric or omental mass is seen with pancreatic, colonic and breast cancer and results from diffuse infiltration, causing thickening and rigidity of the perivascular bundles. Widespread peritoneal metastases, including omental infiltration is a rare consequence of retroperitoneal malignancy, such as renal cell carcinoma (Fig. 3c, 5c)[38].

Metastatic deposits to the ovaries from gastric or colonic primary tumours in association with ascites and other peritoneal deposits are a well-recognized entity. These tumours, known as ‘Krukenberg’ tumours, are presumed to be a consequence of transcoelomic spread and are clearly visualized on CT[39].

Lymphatic metastases

Lymphatic metastases play a minor role in the intraperitoneal dissemination of metastatic carcinoma, but is very important in the spread of lymphoma to mesenteric lymph nodes. Almost 50% of patients with non-Hodgkin’s lymphoma will have mesenteric nodes at presentation, compared to only 5% of patients with Hodgkin’s disease[40]. On CT, mesenteric lymph node involvement in lymphoma produces round or oval masses in the mesenteric fat, which may displace adjacent loops of bowel[35]. Large conglomerations of lymph nodes may surround the superior mesenteric artery and vein on CT and demonstrate the so-called ‘sandwich sign’ (Fig. 7) where lymphomatous mesenteric masses are separated from retroperitoneal lymphadenopathy by an intact anterior pararenal fat plane[35, 41].

Embolic metastases

The abdomen is a common site for haematogenous metastases from both intra-abdominal and extra-abdominal primary tumours. The tumour emboli spread via the mesenteric arteries to deposit on the antimesenteric border of the bowel in the smallest arterial branches, where they grow into mural nodules.

The most common tumours that metastasise embolically to bowel and the peritoneal reflections are melanoma, breast and lung cancer. These metastases often occur several years after treatment of the primary neoplasm. Occasionally bowel obstruction or intussusception, as a consequence of embolic metastases, may be the first manifestation of an occult malignancy.

CT appearances. On CT, embolic metastases may produce thickening of the serosal surface of the bowel, which is often asymmetric and associated with bowel obstruction (Fig. 8a)[42]. They may also appear as well-defined round masses within the peritoneal fat (Fig. 8b). Embolic metastases to the stomach from breast cancer produces marked gastric wall thickening with almost complete obliteration of the lumen, an appearance that is indistinguishable from primary schirrous gastric carcinoma or lymphoma[43].

(b) Axial CT scan in a 40-year-old male with leiomyosarcoma of the retroperitoneum showing multiple well defined soft tissue masses adjacent to the bowel in the mesenteric fat.


Whilst most imaging appearances are non-specific and can also be mimicked by primary peritoneal malignancy and peritoneal inflammatory conditions, some peritoneal metastases have characteristic appearances. Understanding the complex peritoneal anatomy and the methods of spread may suggest the primary malignancy. The CT identification of peritoneal metastases has been correlated with second look laparotomy. The specificity of CT for the diagnosis of peritoneal metastases is high ranging from 85–87%, however its sensitivity is low, ranging from 42–47%[45,46]. Laparoscopy has also demonstrated a significant incidence of peritoneal metastases in patients with a negative CT scan. Notably if ascites is present but no peritoneal deposits are seen on CT, laparoscopy demonstrated deposits in 75% of cases[47]. At present CT remains the most useful imaging modality but recent MR technical developments allow similar accuracy in staging advanced disease.
