“…Uhthoff and coworkers [1,2,3] indicated that the etiology of calcifying tendinitis differs from that of rotator cuff tear: calcification occurs within normal living tissue, whereas rupture seems to take place in a degenerated tendon. However, other authors have hypothesized a closer cause-effect relationship [4,5,6,7,8,9]. We report on a patient in whom progression from calcifying tendinitis to rotator cuff tear was serially observed.…”

“…Some authors have considered the pathogenesis of calcifying tendinitis to be a de- generative process of dystrophic changes in the tendon, in which necrosis of cells and tissue can lead to deposits of calcium and subsequently to rupture of the tendon [4,5]. This theory has been supported by autopsy investigations [6,7], which frequently show full-thickness tears of the rotator cuff together with microscopically visible calcifications of the tendon tissue.…”

“…Some authors have reported that intratendinous calcium deposition can cause tendon rupture [4,5,6,7,8,9]. In the rotator cuff, the tendon strength of the bursal-side layers is biomechanically weaker than that of the joint-side layer [13].…”

This report documents the clinical, radiographic and histologic findings in a 46-year-old man with calcifying tendinitis in his left shoulder which progressed to rotator cuff tear. The patient had a 1-year history of repeated calcifying tendinitis before being referred to our hospital. On the initial visit, radiographs and magnetic resonance imaging (MRI) revealed calcium deposition localized in the supraspinatus tendon without apparent tear. Three months after the first visit, MRI revealed a partial-thickness rotator cuff tear at the site of calcium deposition. Surgical and histologic findings demonstrated that calcium deposition was the cause of cuff rupture. To our knowledge, based on a review of the English literature, this is the first case report in which the progression from calcifying tendinitis to rotator cuff tear has been serially observed.

“…Using conventional radiography, Kemwein ( 1965) found cystic changes in 21% of subjects with intact rotator cuff and 50% of those with rotator cuff tears detectable by arthrography. The incidence of MR-evident cystic changes in shoulders without cuff tears was slightly lower in our study and also in the study by Needell and colleagues.…”

“…These osseous abnormalities, including cortical irregularities and cystic changes, were also visible on radiographs of the shoulder. When localized to the rotator cuff attachment site, they became established as important radiographic signs in the diagnosis of cuff disorders, which occurred in two-thirds of patients with tears but were present in only 13%-27% of normal shoulders (2)(3)(4)(5).…”
