(A) The lesion is located in the left lateral lobe of the liver, mainly in III segment, part of II segment, with a clear realm, a heterogeneous focal mass of expansive growth, irregular patchy low-density areas of internal tissue, uneven strengthening of peripheral tissue, but the density is still lower than that of normal liver tissue. (B,C) The continuity of the lower edge of the tumor is interrupted, and there is a fluid accumulation in the hepatogastric space, which compresses the anterior wall of the stomach. (D) No enlarged lymph nodes are seen in the hepatic hilar, irregular cystic low-density areas appear at the inner edge of the tumor, and postoperative dissection confirms that the bile ducts are locally dilated.

Enhanced CT of the upper abdomen showed left epigastric mass (Figure 1), measuring 12 cm x 10 cm, which probably occurred in the stomach and was considered a gastric stromal tumor.
Massive blood clot located in the hepatogastric space surrounded by dark red unclotted blood.

There existed numerous blood clots in the liver and stomach space, surrounded by dark red unclotted blood (Figure 2).
(A) General specimen: The mass is nodular, appears to have a fibrous envelope, has a clear perimeter, and is about 10 x 10 cm in size. (B) Tumor tissue (hematoxylin-eosin staining x200): Tumor cells under the microscope are seen to consist of a mixture of monocyte-like cells and a large number of osteoclast-like multinucleated giant cells, with mild dysplasia of the nucleus, no pathological nuclear division, accompanied by extensive bleeding and necrosis. (C) GCT-STs are positive for immunostain CD68 (immunoperoxidase x100). (D) GCT-STs are positive for immunostain CD163 (immunoperoxidase x100).

The left lobe of the liver was removed by laparoscopy, surgical specimen, and pathologically related photographs (Figure 3).
