Benign Teratoma in the Left Pleural Space with Amylase in the Pleural Fluid

Abstract

The case of a 28-year-old man who experienced repeated episodes of pleuritic chest pain is reported. Eventual discovery of amylase in the pleural fluid and a supradiaphragmatic mass on computed tomography led to exploratory thoracotomy. A benign cystic teratoma was discovered in the pleural space overlying the left hemidiaphragm and connected by a peduncle to the thymus.
