CT demonstration of extrapleural pedunculated thymoma

ABSTRACT

A case of extrapleural pedunculated thymoma is presented and its CT features are described. A large ovoid extrapleural pedunculated thymoma in the right lower lung field clearly demonstrated a focal tapered pedicle at the level of inferior border of right main bronchus on CT scan, thus establishing the mediastinal origin of the mass in a 61-year-old man.
