Findings:

1.5 Tesla MRI of cervical spine with isotropic three-dimensional T2
 weighted echo train spin echo with parallel imaging, extended echo
 train acquisition, and half-Fourier acquisition (3D-FSE-Cube) with
 multiplanar reconstruction, T2 weighted echo train spin echo with
 iterative decomposition of water and fat with echo asymmetry and
 least-squares estimation (IDEAL), and with intravenous
 gadolinium-enhanced images:

1. A 0.5cm small long T2 cystic lesion in right lateral spinal canal
   with direct extension of right C7-T1 neural foramen, compatible
   with pseudomeningocele from brachial plexus injury with
   right C8 nerve root injury (Fig 1-3).
2. Soft tissue long T2 swelling with mild contrast enhancement
   along right lateral neck, compatible with trauma history
   (Fig 4,5).

Diagnosis: brachial plexus injury with pseudomeningocele
