Traumatic Nerve Root Avulsion and Pseudomeningocele Diagnosed by Three Dimensional MRI Technique (CISS Sequence). A Case Report.

This case report demonstrates the importance of the CISS sequence, a fast imaging technique in MRI, in case of suspected nerve root avulsion. We present a case of traumatic pseudomeningoceles at T1-T2 root levels with right T2 ventral root avulsion without associated skeletal fracture diagnosed by MRI using the three dimensional CISS technique. A 28-year-old man presented to the Emergency Department following a motorcycle accident. Clinical examination revealed paresis in intrinsic muscles of the right hand. Traumatic pseudomeningoceles at T1-T2 root levels bilaterally with right T2 ventral root avulsion without associated skeletal fracture were diagnosed by three dimensional cervicothoracic MRI with CISS technique.
