A 47-year-old female patient with intense left shoulder pain resistant to oral anti-inflammatory drugs and no history of trauma. Oblique coronal fat saturated proton density-weighted MR image (A) performed 1 week after pain onset shows a focal area of hyperintensity within the supraspinatus tendon without fiber retraction, that was described as partial thickness bursal side tear (arrows). Anteroposterior CR of the left shoulder (B) performed 3 days later reveals a large calcification over the humeral head (arrows). The patient underwent shoulder US (C) three weeks later, with long-axis US image of supraspinatus tendon showing fragmented hyperechoic calcification with faint acoustic backs shadow (arrows). Notably, US also showed no evidence of supraspinatus tear
