title: Posttraumatic lumbar intraspinal extradural-intradural ossification.
abstract: A case of intraspinal calcification having mainly the configuration of an intradural cast is presented. The traumatic etiology is obvious, and we consider, that the dural sac and nerve root lacerations were associated with intradural as well as extradural hematomas, which later became calcified.
