Hemangioma Mimicking Left Atrial Mass in the Posterior Mediastinum

A Case Report with Literature Review

Abstract

Primary hemangioma of the mediastinum is extremely rare. Herein, we present a unique case of hemangioma mimicking left atrial mass in the posterior mediastinum. We reviewed the literature and found 17 other hemangiomas in the posterior mediastinum. Herein, we summarize the age, gender, symptoms, diagnostic methods, image diagnosis, size, treatments, histologic features, outcomes, and follow-up of 17 cases. Most of the cases were asymptomatic and were accidentally detected in chest radiographs. Diagnostic methods mainly included chest X-ray, computed tomography (CT), and magnetic resonance imaging (MRI). All patients underwent surgical resection, recovered well, and had no recurrence during follow-up.
