A 51-year-old woman was admitted to our hospital complaining of fever and general fatigue. Physical examination revealed butterfly like erythema in face, facial edema and diffuse purpura all over her body. Laboratory data showed renal dysfunction, nephrotic syndrome and active phase of SLE. She was administered first methylprednisolone (1g/day/3 days by intravenous drip) then prednisolone (60mg/day/month, orally) and had immune adsorption therapy for eight times. However, 14 days after the last session of immune adsorption, she developed fever of 39°C and mild headache, and then 3 days later, she gradually became unconscious. Brain CT showed hydrocephalus. We diagnosed her as having tuberculous meningitis based on the detection of acid-fast bacillus in cerebrospinal fluid, and began treatment with antituberculous agents. We suspected that tuberculous meningitis had caused hydrocephalus. We tried percutaneous drainage of the left ventricle for hydrocephalus. Brain MRI showed a tuberculoma depicted as a mass of low intensity in the right cerebellum on the T 1 weighted image, and of high intensity on the T 2-weighted image, and the meninx in the basal cistern was enhanced. After treatment with antituberculous agents, we performed serial brain MRI and examined cerebrospinal adenosine deaminase activity (ADA). Despite treatment with antituberculous agents, new intracerebral tuberculomas had developed in some areas, whereas they had disappeared in other areas. After treatment for 4 months, the level of cerebrospinal ADA became normal, and the patient recovered consciousness despite the presence of multiple tuberculomas.<BR>Both the cell counts and the level of ADA in cerebrospinal fluid are the good indicators of the activity of tuberculous meningitis and reflected its clinical course. Furthermore, the level of ADA in cerebrospinal fluid changed with brain MRI image. Serial brain MRI and examination of ADA in cerebrospinal fluid were useful to know the activity of tuberculous meningitis and to evaluate the response to treatment.
