Tc-99m RBC imaging yields false-positive hepatic hemangioma in angiosarcoma due to similar vascular histology.
Case Report (n=1)
Hepatic angiosarcoma can mimic cavernous hemangioma on Tc-99m labeled RBC liver imaging, leading to potential false-positive diagnoses.

Clinicians should consider angiosarcoma before diagnosing hemangioma on Tc-99m RBC scans; case report leaves open need for histopathology validation.
Intenzo et al. (1995) conducted a case report in Hepatic angiosarcoma (n=1). Tc-99m labeled red blood cell (RBC) imaging was evaluated on Diagnostic accuracy of Tc-99m labeled RBC imaging. Tc-99m labeled red blood cell imaging can yield a false-positive for hepatic cavernous hemangioma in patients with hepatic angiosarcoma due to similar vascular histology.
