[CT findings of six cases with intracranial tuberculosis in National Higashi-Saitama Hospital].
We have experienced 6 cases of intracranial tuberculosis since 1985. 2 cases were diagnosed as intracranial tuberculoma without tuberculous meningitis, and 4 cases were diagnosed as tuberculous meningitis. Brain CT showed intracranial tuberculomas in three of them, and showed cerebral infarcts in two cases, and showed hydrocephalus in two cases. Brain CT on intracranial tuberculosis showed various findings. In two cases with tuberculous meningitis, brain CT showed many tuberculomas with ringed or nodular enhancement appeared after adequate chemotherapy had been started. About 1 year later, a few tuberculomas were found with homogeneous enhancement and were enlarged while the chemotherapy was continued. But later they were reduced in size. The above facts may suggest that intracranial tuberculoma could appear and be enlarged on cranial CT in spite of adequate anti-tuberculous chemotherapy during a course of tuberculous meningitis. They also suggest that the continuation of adequate chemotherapy might be necessary to the treatment of intracranial tuberculomas.
