Extra-articular contrast material leaks into locations unrelated to the injection path in shoulder MR arthrography

Abstract

• Contrast material extravasation may reduce the diagnostic value of shoulder MR arthrography. • The extravasations may occur into locations unrelated to the injection path. • The extravasations adjacent to axillary recess can be misleading for HAGL lesion. • Massive subscapular extravasations were frequently associated with adhesive capsulitis and SLAP lesions.

Diagnostic Performance of MR Arthrography with Anterior Trans-Subscapularis versus Posterior Injection Approach for Subscapularis Tendon Tears at 3.0T

“…Fourthly, the readers were unable to be completely blind to the injection approach used because the location of subcutaneous oedema or extra leakage might be a clue to predict the injection side. However, these biases were not significant because only T1-weighted images were analysed and the side with extra-articular leakage does not always correspond to the injection side as shown in the recent studies [35,36]. Fifthly, interpretation bias might be introduced to the arthroscopic results.…”

Shoulder MR Arthrography Complication – Direct Injection of the Biceps Tendon: A Case Report

“…Intraosseous and epiphyseal injection has also been reported as a complication [8]. Contrast can be seen in the superior subscapular recess as these as communicate with the joint in 47.5% of cases [9]. Contrast is most commonly seen in the subacromial/subdeltoid space following a full thickness rotator cuff tear [10].…”

Comparison of Ultrasound Guided Deep and Superficial Joint Injections

“…Bu nedenle kıkırdağa temas sonrası iğne minimal geri çekilerek kapsül içindeki negatif basınç içerisinde kalması sağlanır. İğnenin kıkırdağa teması sonrası geri çekilmesi nedeniyle, eklem kıkırdağı ile kapsül arasındaki mesafe enjeksiyonun başarısında önemli rol oynamaktadır (8,9,19). Biz glenohumeral ekleme enjeksiyonda posterior yaklaşımı kullandık.…”
