The role of MR Myelogram in the diagnosis of traumatic pseudomeningocele

Traumatic pseudomeningocele is a valuable indicator of nerve root injury. Secondary to trauma, the traction forces firstly tear meninges and later if the traction forces are great enough, nerve root avulsions occur. In this article, we aimed to show pseudomeningoceles localized at the level of brachial and lumbar plexus secondary to nerve root injury. We retrospectively reviewed the patients who admitted to our hospital between 2009 and 2011 due to various accidents. After clinical and radiological examinations, spinal root injuries were detected in six patients at different levels. Brachial plexopathy was detected in four patients and lumbosacral plexopathy was detected in two patients. Pseudomeningocele is a valuable indicator of nerve root injury. It occurs after dural torn like pouch. MR and MR myelography is the best imaging modality to indicate its’ pouch and cerebrospinal fluid (CSF) within it. MR and MR myelography are best effective imaging modalities to indicate the pseudomeningoceles due to nerve root injury.
