Abstract
A 35-year-old man has been followed for suspected splenic hamartoma since 2005 in the Department of Gastroenterology. The patient complained of exacerbation of abdominal distension and oppressive sensation in January 2010. No abdominal organomegaly or tenderness were observed on physical examination. Ultrasonography (US) revealed multiple hypo-isoechoic, heterogenous nodules with unclear borders, and an increase in the number of masses was observed. Enhanced computed tomography (CT) revealed multiple nodules with heterogenous enhancement in the early phase, but no nodules were detected in the late phase. Non-enhanced magnetic resonance imaging (MRI) revealed no nodules on T1 image, but a low signal intensity mass-like image was observed on T2 image. Uptake by the tumor was observed by ferucarbotran-enhanced super paramagnetic iron oxide (SPIO) MRI, and we therefore strongly suspected multiple splenic hamartoma. Open splenectomy was performed in March 2010. because the case was symptomatic and the patient solicited its resection. The pathological diagnosis was multiple splenic hamartoma (pulposal type). Multiple splenic hamartoma is very rare, and we thus report this case with a review of the literature.
