Table 2 FIGO Staging of endometrial carcinoma and adapted MRI findingsa

From: MRI of endometrium cancer – how we do it

FIGO Stage

Tumour invasion

MR imaging findings


Tumour confined to uterus



≤50 % of myometrium

Abnormal SI in endometrial cavity or confined to inner half of myometrium


>50 % of myometrium

Extends into the outer half of myometrium


Cervical stromal invasion, but not extension beyond uterus

Disruption or focal thinning of cervical stroma


Local or regional spread



Serosa of uterus and/or adnexa

Disruption or irregular uterine contour caused by tumour; ovarian nodular tumour


Vagina or parametria

Direct tumour extension of upper vagina or/and parametrial tissues


Metastases to pelvic and/or paraaortic lymph nodes



Pelvic nodes

Lymph nodes >8 mm in short axis


Paraaortic nodes w/wo pelvic nodes

Lymph nodes >10 mm in short axis


Bladder/bowel mucosa; or distant metastases



Bladder/bowel mucosa

Tumour disrupts bladder or bowel muscle and invades mucosa; not bullous edema


Metastases abdominal and extraabdominal; inguinal lymph nodes

Tumour deposits at distal sites including peritoneal mets, bladder, bone liver mets, and distal lymph node metastases
