Abstract:
We describe a 39-year-old man with spontaneous rupture of a gastric stromal tumor causing hemoperitoneum. Ultrasonography showed a large mass broadly abutting the stomach and liver. Computed tomography demonstrated a heterogeneous enhanced mass arising from the stomach and focal perforation of the tumor with hemoperitoneum; endoscopic ultrasonography showed an exophytic heterogeneous mass originating from the gastric muscle layer. Angiography revealed that the right gastric artery was the main artery supplying the tumor. A gastric stromal tumor with bloody fluid in the peritoneal cavity was seen at the laparotomy. The tumor was excised completely, and subsequent histological and immunohistochemical studies indicated that it was a gastric stromal tumor. We report a relatively rare case of gastric stromal tumor causing hemoperitoneum due to spontaneous rupture of the tumor.
