A case of hydrocephalus secondary to tuberculous meningitis is reported. A 6-month-old baby was admitted to our hospital with a 10-day history of high fever. Neurological examination revealed no abnormal findings other than neck stiffness. Cerebrospinal fluid findings suggested tuberculous meningitis, because of pleocytosis (608/mm3, 100% lymphocytes) and reduced sugar content (19 mg/dl). Mycobacterium tuberculosis was found in cerebrospinal fluid culture. Although anti-tuberculous therapy was administered for 2 weeks, deterioration of consciousness and papilledema appeared. CT scan demonstrated enlargement of the entire ventricular system, indicating communicating hydrocephalus. After a ventricular drainage was performed, consciousness disturbance improved, but the high fever persisted. Judging by cerebrospinal fluid findings, the meningitis seemed to be in the active stage. Therefore an Ommaya reservoir was installed instead of a cerebrospinal fluid shunt for fear of disseminating the tuberculous infection through the shunt tube. However, the hydrocephalus was not well controlled. Consequently, a ventriculoperitoneal shunt was placed, despite the fact that the disease was still active. The fever then gradually subsided, and cerebrospinal fluid findings normalized. The patient was discharged without any neurological deficits one month after emplacement of the ventriculoperitoneal shunt. The antituberculous therapy has been continued, and there is no sign of infection propagated through the shunt 13 months following discharge from the hospital. The result suggests that a cerebrospinal fluid shunt can be placed for hydrocephalus even in the active stage of tuberculous meningitis under antituberculous therapy.

We report a case of refractory tuberculous meningitis which was markedly improved by intrathecal administration of isoniazid (INH). The patient was a 35-year-old woman diagnosed with systemic lupus erythematosus (SLE) at age 25, who was being managed with steroid therapy. She was admitted to another hospital due to miliary tuberculosis at age 34, and after discharge continued with a regimen of 2 anti-tuberculosis drugs (INH. Rifampicin (RFP)). She was admitted to our hospital with severe headache and fever on June 18, 2001. She showed severe meningeal irritation, and cerebrospinal fluid (CSF) examination revealed cell counts of 207/microliter (72% polynuclear cells), protein level of 300 mg/dl, glucose level of 13 mg/dl, chloride (Cl) level of 104 mEq/l, adenosine deaminase (ADA) level of 10.0 IU/l. The CSF culture was negative for Mycobacterium tuberculosis (M. tuberculosis) and direct polymerase chain reaction (PCR) for M. tuberculosis DNA was negative, but nested PCR was positive in preserved CSF samples. Marked leptomeningeal enhancement at the basilar meninges was noted by cranial MRI on gadolinium (Gd)-DTPA enhanced T1-weighted images. We diagnosed her condition as tuberculous meningitis and administered a total of 5 anti-tuberculosis drugs over about 2 months. However, during this period, both her clinical and CSF findings worsened, and she developed severe consciousness disturbance showing marked hydrocephalus on cranial MRI in August 2001. Therefore, we initiated intrathecal administration of INH 100 mg 3 times a week for progressive tuberculous meningitis. After the initiation of intrathecal therapy, both her consciousness disturbance and CSF findings were improved almost immediately. Ventriculo-peritoneal shunt operation was performed for hydrocephalus on September 26, 2001, and her clinical symptoms were further improved. To our knowledge, this is the first reported case of refractory tuberculous meningitis markedly improved by intrathecal administration of INH. Our findings suggested that intrathecal administration of INH was useful for refractory tuberculous meningitis.

Mycobacterium kansasii infection has been reported to be about 20 percent of non-tuberculous mycobacteriosis, and its disseminated type is uncommon and the prognosis is reported to be generally poor. We experienced one case of disseminated Mycobacterium kansasii infection. A 81 year-old man who had been short-bowel syndrome due to the operation for superior mesenteric artery occlusion since 1998 was admitted on April 24th, 2001 to our hospital because of slowly progressive consciousness disturbance and anorexia. He had shown progressive productive cough and respiratory failure and laboratory findings were C-reactive protein elevation and pancytopenia. Human immunodeficiency virus (HIV) antibody was negative. Chest X-ray and computed tomography showed diffuse miliary nodules and infiltrative shadow. Sputum examination was positive for mycobacteria. The cultured isolate was identified as Mycobacterium kansasii. Bone marrow aspirations revealed inflammatory granuloma with necrosis. He was diagnosed as disseminated Mycobacterium kansasii infection and heart failure, and was treated by anti-tuberculosis drugs and diuretics. Treatment was very effective and Chest X-ray findings and respiratory failure had been completely improved. In this case we speculated that the malnutrition due to short-bowel syndrome could be one of the most suspected reasons of Mycobacterium kansasii dissemination. Disseminated Mycobacterium kansasii infection has been rarely reported comparing with the other mycobacterial infections in Japan. However, due to the increasing numbers of immunocompromised hosts with aging, HIV infection, cancer, and steroid therapy, this type of infection will become more common and its earlier diagnosis and adequate treatment will be important to improve the prognosis.
