Posterior Mediastinal Hemangioma: Case Report and Review of Literature

Abstract

H emangiomas are proliferative lesions that are characterized by increased proliferation of vascular endothelial cells and are usually identified after birth. Mediastinal hemangioma is a rare entity that was first reported in 1914 by Shannon. [1] They comprise about 0.5% of all mediastinal tumors. [2] Preoperative diagnosis is difficult because, although there are characteristic findings in radiologic imaging studies, they are present in less than 20% of the cases. [3] Hemangiomas are predominantly seen in the anterior mediastinum. Fewer than 25 cases of posterior mediastinal hemangioma (PMH) have been reported in the English literature, none of which are from Turkey.
