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.
