Idiopathic Spontaneous Intraperitoneal Hemorrhage due to Rupture of Short Gastric Artery Presenting as Massive Gastrointestinal Bleeding: A Rare Case Presentation and Literature Review.

Idiopathic spontaneous intraperitoneal hemorrhage (ISIH) or abdominal apoplexy is due to the tear of an intra-abdominal visceral vessel spontaneously where no cause can be identified. It is an uncommon but potentially life-threatening condition that generally shows up as a diagnostic dilemma as well as is related to formidable mortality. Among all the reported cases, the extemporaneous tear of short gastric arteries is extremely rare, but it has never been reported to present with massive gastrointestinal bleeding. We report a rare instance of idiopathic spontaneous intraperitoneal hematoma eroding the stomach wall, causing massive gastrointestinal bleeding.
