title: [A case report of miliary tuberculosis with tubercular meningitis diagnosed and followed by polymerase chain reaction method].
abstract: We report here a case of miliary tuberculosis with tubercular meningitis in which the polymerase chain reaction (PCR) amplification method was useful for its rapid diagnosis and follow up. A 70 year old male was hospitalized for further examination and treatment of diffuse small nodular shadows on the chest X-ray. After receiving antimicrobial therapy shadows still remained and he gradually lost visual acuity. He had no meningeal signs, and no remarkable finding on cranial CT. Cerebrospinal fluid examination showed increased cell number with predominantly lymphocytes. Cranial MRI (Gd DTPA) showed lateral ventricular ependymitis. Pulmonary tuberculosis and secondary tubercular meningitis were suspected, but we failed to detect microorganisms from the cerebrospinal fluid, gastric juice, sputum, and urine by the conventional method. However, by the polymerase chain reaction amplification method specific DNA fragments of Mycobacterium tuberculosis complex was detected from the cerebrospinal fluid, gastric juice, bronchoalveolar lavage fluid and serum. The final diagnosis of miliary tuberculosis with tubercular meningitis was established. We administered antitubercular drugs and observed the clinical course. He recovered and the polymerase chain reaction showed negative consequences in all samples. The judgement of PCR and the clinical course were compatible and parallel with the clinical course.
