Tc-99m Erythrocyte Localization of an Intramuscular Hemangioma of the Arm

Abstract

An unusual case of intramuscular hemangioma of the left triceps muscle is presented. This tumor may infiltrate the muscle and be misdiagnosed as a malignant neoplasm.

Unusual presentation of intramuscular hemangioma in abdominal oblique muscles

“…Diagnostic imaging with Doppler imaging, MRI, angiography, and Tc-99m erythrocyte localization provides remarkable results. 3,4,16,17 In our study, US of the mass showed a large echogenic solid lesion in the anterior abdominal wall on the right side. This was followed by MRI with contrast showing a large intramuscular mass in the right anterior abdominal wall composed predominantly of adipose tissue with internal linear and nodular high T2 components showing minimal diffusion restriction and enhancement, which are highly suspicious for well-differentiated liposarcomas rather than lipomas.…”
