Lädermann A, Genevay M, Abrassart S, Schwitzguébel AJ - Case Rep Orthop (2015)

Bottom Line: We describe a patient with voluminous calcified mass entrapped in supraspinatus muscle associated with corresponding tendon tear.Discussion and Conclusion.This association has never been described.

ABSTRACT
Introduction. Rotator cuff intramuscular calcification is a rare condition usually caused by heterotopic ossification and myositis ossificans. Case Presentation. We describe a patient with voluminous calcified mass entrapped in supraspinatus muscle associated with corresponding tendon tear. Histological examination corresponded to a calcified hematoma or necrosis. Patient was surgically managed with open excision of the calcified hematoma and rotator cuff arthroscopic repair. At 6 months, supraspinatus muscle was healed, and functional outcome was good. Discussion and Conclusion. We hypothesized that supraspinatus intramuscular calcified hematoma was responsible for mechanical stress on the tendon. This association has never been described.

Radiological evaluation of supraspinatus muscle and tendon. MRA showed a calcified mass, as well as a supraspinatus tendon thinning (a). Preoperative CT was performed for a better definition of the volume of the well-delimited calcified mass into supraspinatus muscle (b). Five years ago, a supraspinatus muscle MRI excluded intramuscular mass on this time (c).

Preoperative CT was performed for a better definition of the volume of the well-delimited calcified mass into supraspinatus muscle (b). Five years ago, a supraspinatus muscle MRI excluded intramuscular mass on this time (c).

Mentions: MRI showed a thinned supraspinatus tendon (Figure 1(a)). A complementary CT scan showed a well-delimited voluminous supraspinatus muscle calcification (Figure 1(b)), as well as an infra-acromial spur. Five years ago, a prior MRI excluded any supraspinatus muscle mass (Figure 1(c)). At this point and with described elements, we suspected the diagnosis of supraspinatus intramuscular calcification.
