Rare and Unusual Occurrence of Splenic Hamartoma on Ultrasonography

Abstract

Vascular tumors constitute the most common primary tumors of the spleen. Splenic hamartoma and littoral cell angioma have been reported only in the spleen. Splenic hamartomas are rare benign vascular tumors which are incidentally detected during imaging and are seldom symptomatic. This case report describes a rare sonological appearance of splenic hamartoma in a 31-year-old female with occasional pain in the left hypochondrium.
