Abstract

Osteochondrosis is a developmental condition affecting the endochondral ossification. It is commonly idiopathic however can be due to vascular anomalies, dietary conditions, hormonal irregularity, or overuse trauma. Osteochondrosis occurring in the inferior pole of the scapula is an extremely rare condition and is referred to as roca disease. A higher degree of suspicion is required especially in a young patient with atraumatic shoulder pain and additional unconventional MRI sequences focusing on the inferior pole of scapula can be taken to rule out such conditions. We report a case of Roca disease in a 16-year male who presented with right shoulder pain. This is the third case report of roca disease in the English literature according to our knowledge and the first case report to demonstrate extensive MRI imaging features with a normal radiograph. Imaging, particularly MRI, plays a pivotal role in the diagnosis of this extremely rare entity. Also, the inferior pole of the scapula is usually not included in routine shoulder MRI imaging thus close scrutiny with additional MRI sequences should be done to diagnose such a rare entity.
