胸椎部硬膜外膿瘍の1例

抄録

A 64-year-old man was admitted to Nagasaki Rosai Hospital on December 29th, 1989. His complaints were paralysis of bilateral lower extremities and urinary disorder. He felt spinal ache on Dec. 10th with no cause and paresthesia of bilateral lower extremities on Dec. 26th. In physical examination we found anesthesia under Th7 neurological level and diminishing of reflexes under the level. Laboratory data showed inflammation and with spinal puncture we suspected existence of obstructive lesion in Th level. With MR imaging we found space occupying lesion just behind of the spinal cord at Th4.5 level. The lesion showed low intensity in T1, high intensity in T2, and the margin of the lesion showed high in T1, low in T2.
We suspected the lesion as spinal epidural abscess and did emergent operation on December 29th, 1989. At operation the lesion was proved to be spinal epidural abscess and we did Th345 laminectomy and rejection of the abscess.
