Calcific tendinitis is a
tendinopathy characterized by the formation of calcium deposits within or
around the rotator cuff tendons in the shoulder, leading to severe pain. It
most commonly occurs in the supraspinatus and infraspinatus tendons due to the accumulation
of calcium hydroxyapatite crystals.1 Diagnostic tools such as radiography, MRI,
and ultrasound are useful for establishing the diagnosis.
Intraosseous penetration is a rare
condition. Cases of intraosseous penetration of calcific tendinitis have been
reported in the insertions of the pectoralis major and gluteus maximus in the
humerus and femur. The region most commonly affected by intraosseous
penetration is the greater tuberosity of the humerus.
In cases of intraosseous
penetration, differential diagnosis should consider malignancies and
osteomyelitis.
