[A case of intracranial tuberculoma]

The patient was a 20-year-old male who was admitted with epileptic seizure in March 5, 1981. For 3 months prior to admission, he had been affected by 3 seizure attacks. At admission, he was completely free neurologically. Laboratory examination showed no abnormality except for markedly positive result of tuberculin reaction test. Chest X-P was normal. Episode of pulmonary tuberculosis was denied. CT revealed irregular shaped low density area in the left postero-parietal region, in which two small high density spots were visualized by contrast enhancement. Craniotomy was made over the left postero-parietal region. The surface of the parietal lobe was slightly hyperemic and edematous. In some parts, the arachnoid membrane was thickened and turbid and cortical vessels involved in it were occluded. Subcortical tissue was softened and appeared necrotic. Two finger's tip sized nodules were touched in it and removed. Histology verified tuberculoma. Post-operative course was uneventful. The anti-tuberculous therapy was started immediately after the operation. CT, 2 months later, showed the low density area reduced markedly in size.
