title: [Extradural spinal hematoma without traumatic bone lesion. Apropos of 9 cases].
abstract: Extradural spinal hematomas observed in 9 cases over a period of 11 years developed in the absence of blood coagulation disorders in 3 cases, during anticoagulant therapy in 5 cases, and during the course of a megaloblastic anemia in one patient. The presence of marked associated myelomalacia was confirmed at postmortem in one case. Etiopathogenic factors remain obscure, particularly in spontaneously developing forms, and careful histologic examination of all clots is necessary to determine possible vascular malformations at the origin of the hematoma.
