Not So Smooth Swallowing-Posterior Mediastinal Smooth Muscle Tumor Presenting as Dysphagia

Abstract

Among etiologies for posterior mediastinal masses, esophageal smooth muscle tumors are uncommon; especially in the upper third of the esophagus as highlighted by our patient’s case. Endoscopic ultrasonography (EUS) has become an effective mode of evaluation for mediastinal masses. Allowing for a minimally invasive approach to achieving tissue diagnosis.
