Severe shoulder osteoarthritis incidentally identified on Chest radiograph, November/December 2010
74 yo male with a history of a thoracic dural AV fistula presented to the hospital with shortness of breath. The patient underwent an AP chest radiograph (Figure 1), which demonstrated a resolving right lower lung pneumonia. It also demonstrated an abnormal appearence to the glenohumeral joints, left more conspicuous than the right. Correlation with prior left shoulder radiographs (Figures 2 and 3) indicated significant progression of disease over a 2 year period. Given the radiographic findings, evaluation of a previously performed cervical spine MRI confirmed the cause of the patient's shoulder findings.
