Bankart lesion with grade V SLAP tear in shoulder MR-arthrogram

Case contributed by Dr Mohamed Hossam el Deen

Presentation

Recurrent attacks of shoulder dislocation.

Patient Data

Age: 30 years
Gender: Male

Pre-injection MRI

Modality: MRI

Pre-injection MRI shows a humeral head bone cyst and fluid signal inside the subacromial bursa with AC joint hypertrophy.

Athrography

Modality: Fluoroscopy

After fluoroscopic guided needle insertion into the right glenohumeral joint, contrast flow passed into the subcoracoid bursa and glenohumeral joint space. No contrast leakage into the sub-acromial or sub-deltoid bursae could be seen, also no leakage along the needle tract was seen after needle withdrawal.

NB: Before needle insertion arm position was adjusted, the humerus was overriding the glenoid cavity. We applied some axial traction to place it again into its anatomical position.

MR-ARTHROGRAM

Modality: MRI

A "non bony" Bankart lesion and a type V SLAP tear are clearly seen. Please see each sequence comment for further reading.

Case Discussion

Bankart lesions are a common cause of recurrent joint dislocation. They may be associated with different grades of SLAP tear or reversed Hill-Sachs lesions in some cases. MRI arthrography is a useful and simple method to study and classify the labral tears.
