Adventitious Bursitis Overlying an Osteochondroma of the Humerus Facing the Thoracic Wall

الملخص EN

One of the complications of osteochondromas is the development of a bursa over the cartilaginous cap.

We report a 15-year-old boy with a rapidly expanded adventitious bursitis overlying an osteochondroma of the humerus facing the thoracic wall, a location not previously reported for such bursa formation.

Magnetic resonance imaging readily showed adventitious bursitis overlying the osteochondroma, thereby dispelling concerns for malignant transformation.
