An 82-year-old woman without previous medical problem noticed vague back pain on December 31, 1989, and was admitted to a hospital because she developed a fever, a rapidly progressive weakness followed by anesthesia of the lower extremities and sphincter disturbance. On myelography and myelo-CT, the spinal cord appeared to be displaced by an extramedullary mass which partially blocked the subdural space at the level of T-9 to L-1. When transferred to our hospital on January 8, 1990, she was febrile and complaining of headache with meningeal signs. Percussion tenderness was present at T-8 to L-1 spinal spinous process. Neurological examination revealed that the patient had mild consciousness clouding, total paraplegia in the legs, sensory disturbance of a partial degree at L-1 to L-3 and totally below L-3, brisk but equal tendon reflexes in the upper extremities, areflexia in the legs with positive bilateral Babinski signs and sphincter disturbance. Otherwise she was neurologically unremarkable. Acute inflammatory reactions were prominent among the laboratory findings on admission. A lumbar tap yielded purulent fluid with more than 170,000 cells/mm3, 5,000 mg/dl of protein, 44 mg/dl of glucose and culture of the fluid isolated Escherichia coli. T1-weighted sagittal MRI disclosed an ill defined mass which showed the same or locally higher with gadopentetate dimeglumine (Gd-DTPA) signal intensity as soft tissue, compressing the spinal cord anteriorly from T-7 to L-3. The lesion was noticed to have a more extensive rostral-caudal extent than was inferred from myelography and myelo-CT.
