This case report describes a rare instance of a giant leiomyoma originating from the mediastinal pleura in a patient who presented with a large thoracic mass. Diagnostic imaging via computed tomography, magnetic resonance imaging, and positron emission tomography revealed a well-demarcated heterogeneous tumor, which was subsequently confirmed as benign through immunohistochemical analysis after surgical resection. The authors review relevant literature to highlight the unusual location and diagnostic characteristics of this specific type of smooth muscle tumor. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

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.
