Imaging Procedures and Findings
T1 and T2 weighted coronal oblique and T1 weighted axial images (images 1, 2 and 3) demonstrate signal void area near the insertion of supraspinatous tendon. Additional T2 weighted fat-saturated sagittal oblique and coronal oblique images (images 4 and 5) reveal a signal void focus within the distal part of supraspinatous tendon. Shoulder radiograph confirms a large region of calcification in supraspinatous tendon consistent with calcific tedinitis.
Calcific tendinitis involves most frequently the supraspinatus, followed by infraspinatus, teres minor, and subscapularis tendons. Patients are typically in middle age. Three to 20% of shoulders with radiographically demonstrable calcification are asymptomatic, and clinical correlation is required to make the diagnosis. Plain films usually are sufficient for the diagnosis. If an MRJ study is obtained, a small calcium deposit may be difficult to detect but typically demonstrates low signal intensity on all sequences, with apparent enlargement of the signal void on T2 * -weighted sequences.
