Primary Mediastinal Leiomyoma Mimicking a Giant Mediastinal Cyst: A Case Report

Abstract

Primary mediastinal leiomyoma is an extremely rare benign tumor of smooth muscle. Most common radiographic appearance is a well circumscribed heterogeneous solid mass. We reported a case of giant cyst-like lesion at the middle mediastinum, which was pathologically confirmed as a primary mediastinal leiomyoma.
