Fatal Hemoperitoneum Secondary to a Spontaneous Splenic Vein Rupture.

Spontaneous hemoperitoneum is rare and is often labeled as idiopathic because the source of bleeding is never found. We report the case of a 35-year-old male who died of a splenic vein rupture. The decedent was a chronic alcoholic with a reported history of cirrhosis and medication noncompliance. Internal examination revealed pale visceral organs, marked hemoperitoneum, a fibrotic/nodular liver, esophageal varices, and a ruptured splenic vein. Pertinent microscopic findings include liver parenchyma with bridging fibrous septa, nodules of regenerating hepatocytes, and the presence of Mallory-Denk bodies. The immediate cause of death was determined to be splenic vein rupture with the underlying cause of death being chronic alcoholism. This case is reported to emphasize the importance of correlating past medical history with thorough vascular dissection in cases of spontaneous hemoperitoneum. In a patient with fatal hemoperitoneum and risk factors for splenic vein pathology (ie, cirrhosis, portal vein hypertension), a high suspicion should be kept for splenic vein rupture.
