[Syphilitic spinal cord gumma].

Syphilitic spinal cord gumma Syphilitic gummas of the central nervous system are exceptional and are in general described in the brain. We report the case of a Brown-Sequard syndrome in a 25-year-old patient. The cervical myelography and the brain CT as well as the vertebro-occipital junction were normal. The diagnosis of multiple sclerosis was evoked and corticosteroid therapy was initiated. The patient experienced clinical improvement. Two years later, the patient was readmitted. Immunological reactions for syphilis were positive, in serum and CSF. Tests for HIV were negative. The MRI showed a cervical spinal cord process at the C3 level with adhesive spinal associated arachnoiditis. Penicillin therapy was started prior to surgery for the spinal process. The syphilitic nature was confirmed by pathology. To our knowledge, the MR appearance of a syphilitic gumma of the spinal cord has not been described previously in the scientific literature.
