Uncommon scintigraphic findings of multiple hepatic hemangiomas

Tc-99m labeled red blood cell scintigraphy is a valuable, noninvasive technique for differentiating hepatic hemangioma from other lesions by demonstrating a "perfusion blood pool mismatch." The characteristic finding on dynamic CT scan of peripheral and subsequent central enhancement is no...

Description
Summary:Tc-99m labeled red blood cell scintigraphy is a valuable, noninvasive technique for differentiating hepatic hemangioma from other lesions by demonstrating a "perfusion blood pool mismatch." The characteristic finding on dynamic CT scan of peripheral and subsequent central enhancement is not usually seen on Tc-99m RBC angiography, probably due to rapid mixing and dilution of the radionuclide and low resolution of the gamma camera. A case of multiple hepatic hemangioma is presented in which Tc-99m RBC dynamic angiography demonstrated peripheral enhancement with subsequent central filling. In addition, delayed static images showed more hepatic lesions.
