Changing appearance of intraosseous calcific tendinitis in the shoulder with time: A case report.

We report a case of a 66-year-old woman who presented with acute shoulder pain. Initial radiographs revealed a sclerotic intraosseous lesion in the greater tuberosity with associated cortical erosions and subacromial calcification. The diagnosis of intraosseous calcific tendinitis was confirmed with additional magnetic resonance imaging and nuclear medicine imaging.
