Infraspinatus and Teres Minor Tendon Calcification with Severe Pain

Abstract

Calcific tendinitis is an extremely common shoulder disorder which affects 2.7 to 10.3% of the adult population. However, clear details regarding the formation of calcific tendinitis have only been found recently, and its pathology still under debate. In this report, we present a case of calcific tendinitis affect both the infraspinatus and the teres minor tendon with both X-ray and ultrasound findings. Calcific tendinitis at the infraspinatus is rare (around 8.4% in all rotator cuff calcific tendinitis), and no separate case report on calcific tendinitis has been reported in the teres minor region in the preceding several years, therefore, the rarity of reporting this case was considered.4 We assume that additional case reports can help to further improve our understanding regarding infraspinatus and teres minor tendon calcification.
