Right arm weakness, spasms/fasciculation, tingling and numbness. There is asymmetric increased T2 signal and thickening involving the right C5-T1 roots which also extends throughout the remainder of the right brachial plexus, at least to the level of the cords. This is not associated with abnormal contrast enhancement. It is also not associated with surrounding mass or abnormal soft tissue signal. This is a nonspecific finding that could represents plexopathy. Only part of the shoulder girdle is included and there is no significant asymmetry or abnormal signal. Susceptibility artifact in the midshaft of left clavicle is probably related to previous clavicular fracture repair. The study is not optimized to assess the cervical spine, but there is no significant cervical spinal canal or right sided foraminal stenosis.
1. Asymmetrically increased STIR signal and mild thickening involving the roots of the right brachial plexus with its extension into the remainder of the right brachial plexus segments suggests brachial plexitis. Otherwise, no evidence of mass lesions or pseudomeningoceles.2. Findings related to left clavicular fracture and surgical repair.
