ABSTRACT Splenosis is defined as viable splenic tissue that is autotransplanted into other compartments in the body. Intrahepatic splenosis is a rare diagnosis that can be difficult for clinicians to identify. The most common causes of splenosis include abdominal trauma and splenectomy. While most patients with intrahepatic splenosis are asymptomatic, in the presence of risk factors of hepatocellular carcinoma, it is paramount to rule out malignancy. In this report, we present a patient with imaging findings concerning for hepatocellular carcinoma, ultimately diagnosed with percutaneous biopsy and technetium-99m-tagged heat-damaged red blood cell scintigraphy-proven intrahepatic splenosis.
