Fine Needle Aspiration of Thoracic Splenosis

Abstract

A left pleural thoracic nodule in subjects with a previous history of traumatic rupture of the spleen must be considered highly suggestive of thoracic splenosis. Scintigraphy with Tc 99 m and magnetic resonance imaging are diagnostic, while FNA, especially in the absence of anamnestic data, can create a pitfall that can induce inappropriate removal of ectopic, normally functioning splenic tissue.
