Case Discussion

This is an uncommon case of acute calcular cholecystitis getting complicated by segmental portal venous thrombosis. Cholecystitis being a hypercoagulable state, disseminated intravascular coagulation may occur and should be looked out for. 

The differential segmental hepatic attenuation is due to the post thrombotic increased hepatic arterial flow to segments V and VIII.
