False-Negative Tc-99m RBC Liver Scintigraphy in Giant Hepatic Cavernous Hemangioma

Hepatic cavernous hemangioma (HCH) is the most frequently seen benign liver lesion, with an incidence of 0.4% to 7.3%. Tc-99m RBC liver scintigraphy provides high rates of sensitivity and specificity in the investigation of HCH. Although false-negative results in small lesions have been reported (less than 2-3 cm), false-negative results in giant HCH have rarely been discussed.
