Synchronous development of HCC and CCC in the same subsegment of the liver in a patient with type C liver cirrhosis

Figure 1 Dynamic computed tomography findings at the onset of double cancer with hepatocellular and cholangiocellular carcinomas. Two tumors, ~1 cm in diameter, were detected on the ventral and dorsal sides of S3. Arrows indicate the tumors (A1, A2 arterial phase; B1, B2 parenchymal phase; C1, C2 delayed phase). Angiographic findings at the onset of double cancer; D: A superior mesenteric arterial angiogram showing a large shunt through the epigastric vein during the portal phase (the arrows); E: Computed tomography during arterial portography (CTAP) showing a ~1 cm defect on the ventral side of S3 (the arrow), which was diagnosed as a classic hepatocellular carcinoma. No defect can be seen on the dorsal side of S3.
