Scapulothoracic Bursitis in a Amateur Baseball Pitcher / 대한스포츠의학회지

ABSTRACT

Scapulothoracic bursitis refers to inflammation of the bursae secondary to trauma or overuse owing to sports activities or work. It usually causes persistent pain and scapulothoracic crepitus by irritation of bursa but can be presented as painless mass around chest wall. We report a case of scapulothoracic bursitis in a baseball pitcher presenting as rapidly growing chest wall mass confused with a soft tissue tumor. Computed tomography and magnetic resonance imaging revealed as a well-demarcated cystic mass situated between the scapula and chest wall. Incisional drainage resulted in complete resolution of the mass within a couple of weeks. Scapulothoracic bursitis may be presented as painless huge mass in overhead sports athlete and one of the differential diagnoses of soft tissue tumor of the chest wall.
