Fig. 13: Peripheral nerve/Brachial plexus injury in two neonates
From: Mechanical birth-related trauma to the neonate: An imaging perspective
Illustration (a) depicting normal brachial plexus. Image parts (b-f) High-resolution, steady state free precession (SSFP) MR images (b-d) in a 4-month-old boy with clinically suspected brachial plexus palsy shows a right-sided pseudomeningocele at C8-T1 level. The C8 nerve root was avulsed. Axial MR SSFP image of the cervical spine (e) in another 2-month-old female with left brachial plexus palsy demonstrated pseudomeningocele formation at the level of C8 (arrow) with disruption of the ventral nerve root (arrowhead). Sagittal MR SSFP image (f) shows disorganized soft tissue within the left C8 foramen with focal enlargement of the nerve at the exit of the neural foramen, consistent with neuroma formation (arrowhead). A smaller pseudomeningocele is also noted at C7 (arrow)
