title: [Spinal subdural abscess--report of a case and a review of the literature of 43 cases].
abstract: Spinal subdural abscess is rare, compared with spinal epidural abscess. The first case was reported by Sittig in 1927. Only 43 cases have been reported throughout the literature. We experienced an atypical fulminant case of spinal subdural abscess, following the operation for intracranial aneurysms. The patient was a 48-year-old male, admitted to our hospital on April 9, 1987 with complaining of sudden headache and vomiting. A lumbar puncture proved subarachnoid hemorrhage (S.A.H.), CT scan revealed saccular aneurysms in left middle cerebral artery and left internal carotid-ophthalmic artery. Radical surgical treatment for those aneurysms was undergone successfully. Neither cerebral ventricular nor cisternal drainage was established. His postoperative course was uneventful until the 9th postoperative day. He suddenly complained of pain in his legs and back, followed by paraplegia, respiratory, and cardiac arrests with clinical course of several hours. Antibiotics had been used for eight days after surgery, and there was no clinical evidence of inflammation sign. For his abrupt aggravation, a spinal infarction was suspected. However, the autopsy demonstrated that the dorsal side of the entire spinal cord was covered with masses of pus, and central necrosis and hemorrhage of the spinal cord mainly occupied the central gray matter; so-called Pencilsharped softening. In this case, the cause of spinal subdural abscess was unclear. But the lumbar puncture performed on the day of admission, was most responsible. Also, the reasons why the clinical course of our case was rapid and fulminant were discussed with preference of spinal abscess to primary spinal circular disorder. 44 cases in the literature, including the presented report, was reviewed. Those symptomatology, predisposing factors, pathogenesis, the extent of spinal subdural abscess, clinical diagnosis, treatment, and prognosis were discussed. Among previous cases, this case was one of the most extensive subdural abscess and fulminant clinical course.
