The patient is a 44 year old female who was found to have an incidental heterogeneously enhancing splenic mass on CT scan. A follow up CT scan 2 years later demonstrated a solid appearing splenic mass with peripheral enhancement on the arterial phase and progressive enhancement on the portal venous phase. The size had increased from 1.6 cm to 2.9 cm so a splenectomy was performed.

GROSS DESCRIPTION

The spleen grossly weighed 123 grams. Within the lower pole, there was a well circumscribed, red and tan, 3.1 x 2.7 x 2.2 cm mass which abutted the capsule. The remaining splenic parenchyma was unremarkable.
