Posttraumatic spinal pseudomeningocele: MR and clinical features.

Pseudomeningocele results from a tear of the dura leading to extravasation of CSF and formation of a CSF collection that may develop a fibrous capsule [1 -3) . The usual cause is an unintentional tear of the dura during surgery [4). Rarely, a pseudomeningocele may develop after trauma to the spine. We report a case of a posttraumatic pseudomeningocele, not only because of the unusual clinical manner in which it was manifested but also because of the MR features , which allowed the diagnosis of its extradural intraspinal location.
