A case of an syphilitic intraspinal gumma is reported. A 48 years-old woman developed severe spastic crural paraparesis of two months duration, associated with sensory and sphincteric disturbances. Myelography revealed an intraspinal tumor at T3 level. Surgical exploration by dorsal laminectomy showed a syphilitic gumma attached to the spinal cord. Clinical observations and laboratory studies are discussed. Revision and comments on previous reports are presented.
