LIVER HEMANGIOMA - A PERIOPERATIVE TC-99M RBC SPECT CORRELATION

Scintigraphic diagnosis of a liver hemangioma may be difficult when it s 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 cont ribution 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-colloi d SPECT of the liver, Tc-99m labeled RBC SPECT disclosed a focus of in creased activity consistent with the hemangioma.
