The patient is a 34-year-old male who complained of poorly defined thoracic pain, with no dysphagia, reflux or vegetative symptoms. Chest radiograph demonstrated a mediastinal mass. CT was ordered, which detected findings of a well-defined homogenous mediastinal mass that caused narrowing of the esophagus, measuring 10.9cm×3.3cm, reaching from the thoracic opening until several centimeters below the carina (Fig. 1). The esophagus-gastro-duodenal study showed an extrinsic lesion measuring 11cm×4cm that affected the left esophageal anterolateral region (Fig. 2). Endoscopic ultrasound confirmed the presence of a subepithelial mass within the esophageal wall. FNA results were compatible with leiomyoma. Esophagectomy was performed, and the pathology results confirmed the mass as a multinodular esophageal leiomyomatosis.
Diagnosis: Multinodular esophageal leiomyomatosis.
