Acute abdomen secondary to massive bleeding due to rupture of liver metastases of a gastrointestinal stroma tumor.

Hemoperitoneum secondary to non-traumatic liver rupture is a rare cause of an acute abdomen. We present the case of a patient with a hepatic rupture secondary to metastasis of a gastrointestinal stromal tumor (GIST) who required an emergent laparotomy due to hemodynamic instability. Intraoperatively, a lesion of more than 20cm dependent on the posterior gastric wall and a hemoperitoneum secondary to rupture of liver metastases and decapsulation of the Glisson capsule was evidenced. A frequent complication of GIST tumors is its rupture causing gastrointestinal bleeding or hemoperitoneum, as occurred in our case.
