Preoperative abdominal CT and MRI. (A) CT scan in arterial phase, (B) CT scan in venous phase; (C) MRI scan in arterial phase, (D) MRI scan in hepatobiliary phase. Abdominal CT and MRI images showed an oval and smoothly mass located in the liver-kidney space (red circle).

Abdominal contrast-enhanced computed tomography (CT) scan showed that the retroperitoneal tumor (11.8 x 11.0 x 8.3 cm) located in the right adrenal region, with obvious enhancement in arterial phase and continuous enhancement in venous phase ( Figures 1A, B ). Magnetic resonance imaging (MRI) displayed uneven enhancement in arterial phase and no abnormal signal focus in hepatobiliary phase ( Figures 1C, D ).
Gross specimen and HE staining. (A) Macroscopic features of the excised hepatocellular carcinoma demonstrating a solid tumor with a fibrous capsule and intratumoral hemorrhage, (B) HE staining of the tumor confirmed poorly differentiated carcinoma morphologically, magnification x 100. The hepatoma cells were large, polygonal, rich in cytoplasm and red staining, and were diagnosed as massive beam and cord liver cancer.

Histopathological examination of tumor specimen showed that there were a large number of hepatoma cells arranged in beam, cord and nest shapes ( Figure 2 ).
Postoperative abdominal CT. (A) CT scan in plain scanning, (B) CT scan in arterial phase. Postoperative abdominal CT images showed no new mass in the liver-kidney space (red circle).

CT scan showed postoperative changes, and no tumor recurrence was found ( Figure 3 ). Currently, twelve months have passed, the patient is still alive without recurrence.
