Spinal subdural abscess

Abstract

Only 44 cases of spinal subdural abscess have been reported to date. The authors present another case and review the relevant literature. The findings of intraspinal gassification on computerized tomography scans and Escherichia coli as the causative organism have not previously been described in relation to spinal subdural abscess. Most frequently, Staphylococcus aureus is the responsible organism. Hematogenous spread of infection from a distant source often takes place. In a surprising number of incidences, iatrogenic causes are the primary foci of spinal subdural abscess. Spinal subdural abscess is an unpredictable disease, with an unfavorable outcome if left untreated. If there is suspicion of a spinal subdural abscess, urgent radiological examination followed by immediate surgical drainage and appropriate antibiotic therapy is warranted.
