 Please note this examination is technically degraded, particularly the axial T2 fat-sat sequences. Coronal STIR images demonstrate grossly symmetric T2 hyperintensity involving the nerve roots of the brachial plexus proximally. There is suggestion of asymmetrically increased T2 hyperintensity involving the left C6 and C7 nerve roots and to a lesser degree C8 nerve roots more distally; findings seen on axial series 6 images 18 and 19; coronal STIR series 4 image 17. In retrospect, there appears to be subtle increased T2 signal involving the left C6 to left C8 nerve roots in the same region on prior brachial plexus MRI studies.No lymphadenopathy or extrinsic masses within the neck are appreciated. There is volume loss involving the left sternocleidomastoid muscle which was present on prior CT. Degenerative changes in the cervical spine are partially imaged.
Examination is suboptimal in quality and if clinically indicated repeat examination may be considered. There is however suggestion of subtle increased signal involving the distal aspects of the left C6 to C8 nerve roots which in retrospect also appears to be present on prior MRI from 1/13/2011 and 8/4/2009 studies. Findings may represent sequela of prior radiation. No obvious lymphadenopathy or masses to suggest extrinsic compression are appreciated. MRI with gadolinium may be helpful to identify the areas of scarring if surgery is contemplated.
