Continued right forearm and hand numbness and weakness following right shoulder arthroscopy on 5/14/15 using a single shot interscalene block. There is mild diffuse high T2 signal and swelling centered in the right posterior triangle, but also extending into the right axilla and portions of the anterior neck along the fascial planes. The right brachial plexus appears to be grossly intact. There are partially-imaged right shoulder postoperative findings and effusions. The cervical spine appears to be unremarkable.
Mild diffuse high T2 signal and swelling centered in the right posterior triangle may be procedure-related and may consist of edema and/or hemorrhage. The right brachial plexus otherwise appears to be grossly intact. Please refer to the separate shoulder MRI report for additional details.
