title: Lumbar nerve root avulsion following trauma: balanced fast field-echo MRI.
abstract: Lumbosacral nerve root avulsion uncommonly complicates major trauma. Most patients also have pelvic or lumbar fractures. We present a patient who had a high-velocity vehicle accident with traumatic hip dislocation without fractures of the spine or pelvis. MRI demonstrated lumbosacral traumatic pseudomeningoceles. We used balanced fast field echo and MR myelography to make the diagnosis and show the extent of the pseudomeningocele.
