Abstract
Actinomycosis of the central nervous system is very rare. A man aged 48 was admitted to the Ekisaikai Hospital with tetraparesis and urinary obstruction. Myodil myelography showed a complete block at Th4. Laminectomy was carried out from C6 through Th5. Epidural granuloma was found and removed subtotally. The vertebra was not eroded. Pathological diagnosis was actinomycotic granuloma. No cervicofacial, thoracic, or abdominal focus was found. Two years after the operation, he has now completely recovered. This case is probably the first report of spinal epidural actinomycotic granuloma.
