MRI of neurogenic thoracic outlet syndrome

Right brachial plexus magnetic resonance neurography. Coronal and axial T1-weighted images (A, B) and coronal fat-suppressed T2-weighted neurographic image (C) reveal a thick fibrous band (arrows in A and B) causing distortion and edema of the right brachial plexus (arrowheads in A and C). Oblique coronal fat-suppressed T2-weighted neurographic image (D) further illustrates a selective thickening of C8 root (arrowheads).
