Mediastinal Hemangiomas: two cases report and literature review

Abstract

Mediastinal hemangiomas are rare benign tumors of vascular origin. Here we report two cases of mediastinal hemangiomas with different image features. The first case is a 58-year-old man who had a large solitary hemangioma in the posterior mediastinum with well-defined capsule and small punctate calcification. The second case was a 57-year-old female with two hemangiomas in the anterior and middle mediastinum separately. Although mediastinal hemangiomas are rare tumors with various image features, we should keep this tumor in mind as one of the differential diagnoses, especially when the lesions show well-defined margins, peripheral enhancement, presence of phleboliths and dilated drainage veins.
