A, Brachial neuritis with long thoracic nerve neuritis. A, Brachial neuritis with long thoracic nerve neuritis. A 54-year-old man with right shoulder pain and right scapular winging for a few months. Coronal 3D STIR SPACE image shows the asymmetrically hyperintense and enlarged C7 nerve (large arrows). The abnormality extended into the middle trunk and its divisions (not shown). Notice normal left C7 nerve root (small arrows). Sagittal STIR (B) image shows the abnormally enlarged and hyperintense long thoracic nerve along its course (arrow). Axial STIR (C) image through the chest shows atrophy and edema like signal of the right serratus anterior muscle (small arrows). Notice the normal left serratus anterior muscle (large arrow). A.
