Case 2: Clinical photograph (A) showing chronic ulcer in the left thenar eminence (C7 dermatome). Pretreatment magnetic resonance imaging (MRI) images: (B) T2-weighted sagittal image of the cervical spine showing linear hyperintensity in the cervical cord at the C6 and C7 levels; (C) T2-weighted axial image of the cervical spine at the C7 level showing hyperintensity located predominantly in the left hemicord with extension across the midline slightly to the right side (inset); (D) coronal short inversion time inversion recovery (STIR) image showing thickening of the left brachial plexus. Posttreatment MRI images: (E) Post-contrast T1-weighted sagittal image of the cervical spine does not show any enhancement; (F) coronal 3D STIR imaging of the brachial plexus shows persistent thickening of the brachial plexus on the left side; (G) maximum intensity projection images of the coronal 3D STIR showing normal right and thickened left brachial plexus; (H) post-contrast coronal Dixon fat saturated image shows enhancement of the left brachial plexus.
