The typical localization are the vertebral spine and the skull. There is no reported case of an intraarticular glenoidal hemangioma so far. The current paper presents a case of a 48-year-old female with joint pain that started 2 years before. The clinical manifestations included limited range of motion (ROM) and load dependent, non-load dependent and night pain. Roentgenogram and magnetic resonance imaging (MRI) of the left shoulder showed degenerative changes of the glenohumeral cartilage and a big (11.8mm x 10.3 mm) intraglenoidal mass affecting the joint line. The postoperative pathological diagnosis was that of a cavernous hemangioma. The aim of the present study was to present the imaging presentation of glenoidal hemangioma and to show therapeutic options in case of glenohumeral osteoarthritis (OA) with glenoidal bone loss due to hemangioma. In the present case no recurrence of the hemangioma and no complications of the implant in terms of loosening, infection or consisting were observed.Keywords: Hemangioma, tumor, glenoid, arthroplasty, shoulder
