Abstract
Cavernous hemangiomas are the most common lesion of the liver. Because of the risk
of hemorrhage inherent in percutaneous biopsy of such lesions, noninter-ventional
modalities (such as CT, ultrasound, MRI and Technetium-99m red blood cell imaging)
have been utilized for differentiating them from other lesions. The sensitivities
and specificities of these techniques vary greatly. Technetium-99m red blood cell
imaging with planar and SPECT imaging has been shown to have an overall sensitivity
of 89%, a specificity of 100%, and an overall accuracy of 92%. Despite its high accuracy,
rare false positives have been reported with Technetium-99m red blood cell imaging
with SPECT. Review of the literature indicates four cases of hepato-cellular carcinoma,
one case of hepatic angiosarcoma, and one case of hepatic metastases from colorectal
carcinoma as having an appearance identical to hemangioma with this modality. We present
an additional false positive of a focal region of intrahepatic extramedullary hematopoiesis
in a patient with Gaucher's disease as having an appearance on Technetium-99m red
blood cell imaging with SPECT identical to that of hemangioma.
