[A case of early syphilis presenting general paresis-like symptoms and bilateral tonic pupils].

ABSTRACT

A 40-year-old man was admitted after 8 months of speech disturbance and locomotive ataxia. He had no seizures, lightning pains, paresthesia, visual loss, bladder disturbance or rectal incontinence. He had never been neurologically or psychiatrically ill and had no history of syphilis. When the patient was admitted, his general physical examination including blood pressure and dermatologic examination was normal. His consciousness was alert. He was found to have a deterioration of mental status such as inability to concentrate, failing memory, amnesia and circumstantiality. His pupils were anisocoric and Achilles jerks were absent. No rigidity of the neck muscles, paralysis and sensory disturbance were recognized. Romberg's sign was absent. The right pupil was 7.0 mm and the left was 6.0 mm in room illumination. The pupils were nonreactive to bright light and both did not constricted to near stimuli. 0.125% pilocarpine eyedrops produced bilateral pupillary constriction. The results indicated bilateral tonic pupils. Laboratory data revealed white cell count of 12,600/mm3 and normal erythrocyte sedimentation rate of 8 mm/hr. Cerebrospinal fluid (CSF) examination revealed the following opening pressure, 140 mm of water; cell counts, 76/mm2 (mononuclear cells); total protein, 116 mg/dl; glucose, 57 mg/dl. A serum venereal disease research laboratories (VDRL) test was positive in a 132 titer confirmed by positive treponema pallidum hemagglutination (TPHA) test in a 140,960 titer and positive fluorescent treponemal antibody-absorption (FTA-ABS) test. Serum TPHA-IgM was positive in a 1320 titer but TPHA-IgG was negative. CSF examination revealed positive TPHA test (titer of 12,560) and positive FTA-ABS test.(ABSTRACT TRUNCATED AT 250 WORDS)
