Diagnosis of hepatic hemangioma with 99mTc-labeled red cells: single photon emission computed tomography (SPECT) versus planar imaging

Liver hemangioma. A perioperative Tc-99m RBC SPECT correlation

Scintigraphic diagnosis of a liver hemangioma may be difficult when its size approaches the spatial resolution of a gamma camera, and it may not be visualized on a Tc-99m tin-colloid liver SPECT study. The contribution of Tc-99m labeled RBC scintigraphy is shown in a patient with a liver hemangioma discovered during laparoscopic cholecystectomy for chronic cholecystitis. Despite negative CT, US, and Tc-99m tin-colloid SPECT of the liver, Tc-99m labeled RBC SPECT disclosed a focus of increased activity consistent with the hemangioma.
