Breast Hemangioma Evaluation with Magnetic Resonance Imaging: A Rare Case Report

Abstract

Vascular tumors are rare in the breasts, and the most common forms include hemangiomas and angiosarcomas. Hemangiomas are rare benign vascular tumors. Most of them are asymptomatic and nonpalpable clinically, and the vast majority of such lesions are detected incidentally by mammography. Breast hemangiomas are difficult to diagnose using conventional imaging modalities since their imaging findings are variable. The following is a case presentation of an asymptomatic forty-five-year old female patient who was diagnosed with a rare hemangioma. Physical examination, ultrasonography (US) and mammographic examination were normal. Dynamic contrast enhanced magnetic resonance imaging (MRI) showed a non-mass pathological enhancement. After a short-term follow up, a comparative MRI was obtained and biopsy was planned, due to the heterogeneous non-mass enhancement on MRI. Needle core biopsy with US guidance was performed, resulting in benign findings. However, because of the discordance between imaging and histopathology, an MRI-guided wire localization followed by open surgical biopsy was performed. Histopathologic evaluation reported capillary hemangioma.The imaging findings, including US, mammography and MRI, of hemangioma are reviewed and described in this case report.
