Radical resection of hepatic polycystic echinococcosis complicated with hepatocellular carcinoma: A case report

Figure 1 Preoperative images. A polycystic cystic echinococcosis (CE) lesion complicated with multiple hepatocellular carcinoma (HCC) nodules in the left lobe of liver (orange arrow represents hepatic CE lesion; white arrow represents HCC lesions). A: Computed tomography (CT) in the arterial phase showing obvious enhancement of the HCC lesions; B: The portal phase of CT revealed a washed-out pattern of the HCC lesions; C: A delayed CT scan showed HCC lesions without significantly retention; D: IQQA-Liver system three-dimensional reconstruction image.

Figure 2 Microscopic histopathology images (× 100). A: Section of specimens showed complete cyst wall structure, consistent with histopathological characteristics of cystic echinococcosis; B: Multiple highly differentiated cancer cells are found in the section specimens.

Figure 3 Intraoperative photos. A and B: The yellow arrows represent hepatic cystic echinococcosis lesions and the white arrows represent hepatocellular carcinoma lesions.

Figure 4 Magnetic resonance images 3 mo after surgery, showing no significant recurrence lesion (A-D).
