Subacromial impingement syndrome (SAIS) is one of the most frequent causes of shoulder discomfort. Osteochondroma-related subacromial impingement syndrome is rarely reported in the literature. In this case report, we describe the treatment of a 19-year-old female patient with a solitary osteochondroma who presented with pain and restricted movement in the shoulder region. Direct radiography indicated that a bone density mass had almost completely filled the subacromial region. The unique aspect of this report was the origin of the exostosis. Although osteochondromas originating from the posterior superior glenoid are uncommon, they can cause SAIS. Removal of the mechanical irritation with arthroscopic or open surgical techniques can reduce pain and facilitate recovery of shoulder function.
