Case list for Metastasis - Pancreatic Cancer
There are 2 CT cases with this diagnosis.
Multiphase CT reveals multiple hepatic metastases that are hypodense on all phases. Note central necrosis of even small metastases. Biopsy of one of these liver lesions was revealed poorly differentiated adenocarcinoma, compatible with pancreatic origin. Hypervascularity in the left lobe is due to chronic occlusion of the left portal vein (not shown). Images in this patient after chemotherapy and transarterial chemoembolization (TACE) can be seen here.
Multiphase CT shows multiple hypovascular metastases with reactive hypervascular perfusion abnormalities (transient hepatic attenuation differences - THADs). Metastases are largely necrotic and demonstrate an almost uniformly thin hypovascular rim on arterial and portal venous phase, while the hypervascular hepatic parenchymal perfusion abnormalities are of variable thickness and irregular. There is also a subsegmental wedge shaped THAD in segment 8 (5th image arrows).
Hypovascular primary tumor in the pancreatic tail, representing moderately differentiated adenocarcinoma. Hypervascular rim around pancreatic cancer metastases is a commonly seen feature.
