Description
Summary:Hepatic splenosis, a rare entity, is the ectopic implantation of splenic tissue into the hepatic parenchyma, most often incidentally seen in patients with a history of splenic trauma and splenectomy. We present a unique case of hepatic splenosis in a patient with hemosiderosis and splenectomy following the incidental finding of hepatic masses on pretransplant imaging. Final diagnosis was made based on cross-sectional imaging characteristics matching that of the left upper quadrant splenules alone. We discuss common characteristics of hepatic splenosis on multiple modalities, the effect of iron deposition on the imaging characteristics of hepatic and splenic tissue and how that impacts the differential and diagnosis. This case highlights the unique imaging characteristics hepatic splenosis can have particularly in the setting of hemosiderosis. Hepatic splenosis imaging diagnosis has a significant advantage over tissue diagnosis in terms of decreased risk, time and cost.
