title: [Synovial chondromatosis as an unusual cause for subacromial impingement in a tennisplayer].
abstract: On the one hand synovial chondromatosis is a rare disorder and usually involves the knee and hip but rarely the shoulder joint. On the other hand bursal causes of impingement are rare too. We report a case of synovial osteochondromatosis presenting as chronic impingement syndrome in a 44 year old hobby tennis player. In the course of four years impingement problems and a "tumorous" growth on the outer surface attacked attraction to the patient. An MRI presented several nodular structures with sclerosis in the anteriomedial region of the shoulder joint. The mass was completely removed by operative treatment. The histological result showed a synovial chondromatosis with chronical synovitis. After the operative exstirpation of the calcified bodies the patient had no discomfort for 15 months and is now able to play tennis again.
