[Spontaneous extradural XXXX localized in the ventral side of the thoracic spinal cord--a case report].

@entity1 @entity4282 @entity548 @entity439 @entity1410 @entity158 @entity912
A case of spontaneous spinal extradural @entity1410 was reported. The @entity1 , a 25-year-old housewife, was hospitalized with back @entity158 , followed by @entity912 of both legs and urinary disturbance during next 2 hours. A myelogram demonstrated that contrast medium was incompletely blocked at the level from the 3rd to the 4th thoracic spine by extradural mass. Unfortunately X-ray CT scan was not examined, however, a NMR-CT scan excluded disc protrusion and dissecting @entity439 of the aorta. Eight hours after onset, wide laminectomy was performed as emergency operation and an @entity4282 located in the ventral side with compression of the thoracic cord was removed as completely as possible. She was discharged with excellent recovery after operation. The spontaneous @entity4282 is rare emergency. The exact etiology is unknown, and no explanation is offered as to why the @entity1410 is usually dorsal in location. To our knowledge, only three cases of @entity4282 which located in the ventral side were reported. Considering from our experience and other reports, it seems to be the most important point to avoid the unnecessary pressure on the spinal cord and to search the exact @entity548 point in the operative procedure of @entity4282 .
