    Abstract:
    A case of multiple intracranial tuberculomas diagnosed by enhanced brain CT scan and MRI, which developed during the course of miliary tuberculosis under anti-tuberculous chemotherapy was experienced. Chemotherapy with an increased dose of each agent and corticosteroid was administered, and eventually intracranial tuberculomas nearly disappeared. After 1970, there have been 29 reported cases of intracranial tuberculomas in Japan, which were diagnosed by brain CT and treated with anti-tuberculous agents. Among them, 27 evaluable cases were classified into 3 groups. Group A: Intracranial tuberculomas were proved by CT before chemotherapy in 7 cases. Four of them enlarged during chemotherapy. Group B: During chemotherapy of tuberculous meningitis, neurological symptoms worsened or prolonged, and finally intracranial tuberculomas were found by CT in 9 cases. In 5 of them, after meningitis was improved by chemotherapy, neurological symptoms worsened and intracranial tuberculomas were found. Group C: During chemotherapy of pulmonary tuberculosis or miliary tuberculosis, neurological symptoms appeared and intracranial tuberculomas were found by CT in 11 cases (including our own case). Getting 3 groups together, intracranial tuberculomas seem to have worsened during chemotherapy in 24 out of 27 evaluable cases. In view of response to chemotherapy, these 24 cases can be divided into 2 categories: 1) non-responders to chemotherapy; 2) cases finally cured by chemotherapy ("transient worsening").(ABSTRACT TRUNCATED AT 250 WORDS)
