Abstract

This report presents a rare case involving a patient with a giant leiomyoma originating from the mediastinal pleura. The patient underwent a medical examination, and chest radiography revealed a giant tumor. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a well demarcated, heterogeneous mass which seemed to originate from the posterior mediastinum. Positron emission tomography (PET) showed the uptake of this tumor with a standardized uptake value of 4.9. We suspected that this tumor was a solitary fibrous tumor, and the patient underwent a surgical resection. Intraoperative exploration revealed a well-encapsulated tumor measuring 15 × 11 cm that appeared to originate from the mediastinal pleura. Immunohistochemical findings revealed a benign leiomyoma. We finally diagnosed the patient with a mediastinal leiomyoma. The present report describes CT, MRI, and PET findings of leiomyoma, and presents a review of relevant literature.
