Abstract
Aims: To describe the finding of edema-like intensity beneath the coracoacromial ligament (CAL) on shoulder magnetic resonance (MR) images of patients referred with shoulder pain and/or with the presumption of rotator cuff pathology. Methods: A total of seven patients were included in the study group having edema-like intensity beneath the CAL on fluid sensitive sequences. None of the patients had any other additional findings such as effusion in the subacromio-subdeltoid bursa, degeneration of the acromioclavicular joint or the rotator cuff rupture. The images of the patients were obtained using two different scanners of 1,5T (six patients) and 3T (one patient). The thickness of CAL at its midportion was also measured. Results: A total of seven patients were included. There were five women and two men with a mean age of 39,28 years. Four of the patients were referred to imaging with the suspicion of rotator cuff pathology only, one patient for having pain in the shoulder and two having both pain and suspicion for rotator cuff pathology. The best imaging plane for this finding of edema- like intensity beneath the CAL was the sagittal plane. The ligament thickness was measured with a mean value of 0.94 mm (between 0.66 mm-1.32 mm). Conclusions: The edema-like intensity restricted beneath the CAL without thickening of the ligament can go with symptomatology as seen in subacromial impingement syndrome. Hence, it is valuable to look for and concern this intensity even if it is the sole finding on shoulder MR images, as a possible indication for symptomatology.
