Massive upper gastrointestinal haemorrhage due to intragastric rupture of a splenic artery aneurysm.

Most cases of splenic artery aneurysm are asymptomatic, being found incidentally at the time of investigations (e.g. ultrasound, computed tomography, angiography) or laparotomy for other conditions. Rupture of a splenic artery aneurysm with erosion into the stomach is a rare cause of massive upper gastrointestinal haemorrhage. This case report is, to our knowledge, only the second case of splenic artery aneurysm presenting with massive upper gastrointestinal haemorrhage due to erosion into the stomach in a nulliparous woman.
