“…12). 48 This type of insertion has been reported to be associated with instability but is often seen in normal patients without instability. An avulsion of the IGHL at the glenoid attachment is called a GAGL lesion, and it has a "J" configuration on coronal images in the opposite direction of a HAGL lesion.…”

The glenohumeral joint is an inherently unstable articulation and consequently the most frequently subluxed and frankly dislocated joint in the body. Shoulder instability can be uni- or multidirectional related to acute or repetitive stress and is occasionally secondary to congenital or developmental abnormalities such as a lax joint capsule or glenoid dysplasia. The clinical diagnosis of instability can be difficult, and knowledge of the imaging findings of anterior, posterior, multidirectional, and microinstability is essential to guide the correct treatment of these patients. This requires the appropriate use of many different imaging modalities as well as specific positioning and directed protocols. This review article explains the clinical scenarios associated with shoulder instability and how they relate to the choice of imaging techniques. The imaging findings of the most common soft tissue and osseous pathology are reviewed and explained with specific attention to anterior and posterior instability.

“…The glenoid cavity may be concave inferiorly or concave superiorly. An area of thickened subchondral bone near the center of the glenoid fossa has been termed the tubercle of Ossaki (Fitzpatrick and Walz 2010). Full-thickness cartilage defects can also been seen of the glenoid fossa on imaging (Fitzpatrick and Walz 2010).…”

“…The tendon attachment to the superior labrum also changes according to contributions from both its anterior and posterior aspects, described as follows ( 2 ) : 1) posterior labrum only; 2) predominantly from the posterior labrum with small site of attachment to the anterior labrum; 3) identical origins from the anterior and posterior labrum; 4) predominantly from the anterior labrum with small site of attachment to the posterior labrum. Rarely, portions of the biceps tendon may also attach to the capsule itself; to the rotator cuff; or directly to the supraglenoid tubercle ( 3 - 5 ) .…”

Magnetic resonance imaging has revolutionized the diagnosis of shoulder lesions, in many cases becoming the method of choice. However, anatomical variations, artifacts and the particularity of the method may be a source of pitfalls, especially for less experienced radiologists. In order to avoid false-positive and false-negative results, the authors carried out a compilation of imaging findings that may simulate injury. It is the authors’ intention to provide a useful, consistent and comprehensive reference for both beginner residents and skilled radiologists who work with musculoskeletal magnetic resonance imaging, allowing for them to develop more precise reports and helping them to avoid making mistakes.
