Contrast enhanced axial CT in three patients with nodal metastases from primary ASPS (a-c). Left hilar nodal tissue in a 31 year old male patient demonstrates high attenuation with prominent central vessels (a, white arrow). Feeding vessels are demonstrated alongside and within nodal disease in a 37 year old male patient (b, black arrow). Metastatic mediastinal nodal disease in a 28 year old female (c) demonstrates marked central necrosis, however peripheral hypervascularity is still appreciated (c, black arrowheads)
