Temporary Spontaneous Thrombosis of a Splenic Artery Pseudoaneurysm in Chronic Pancreatitis during Intravenous Octreotide Administration

Splenic artery pseudoaneurysm is a well-known and potentially life-threatening complication of pancreatitis for which immediate endovascular or surgical treatment is indicated. An unusual case of spontaneous thrombosis of a splenic artery pseudoaneurysm with associated partial splenic infarction was encountered in the setting of chronic pancreatitis during intravenous octreotide administration, with recanalization 9 months later.
