[A case of pulmonary tuberculosis complicated with intracranial tuberculous abscess]

A 75-year-old male was admitted to our hospital with complaints of fever and cough. Chest X-ray showed infiltrative shadows with cavity, and sputum smears were positive for acid-fast bacilli. About 2 months after the initiation of anti-tuberculous chemotherapy, suddenly generalized convulsion occurred. CT of the brain showed the solitary mass with the ring enhancement in the left subcortical area. About 4 weeks later, brain aspiration drainage was performed and pus was aspirated. He was diagnosed as intracranial tuberculous abscess. After the drainage, neurological symptoms disappeared completely and there were no recurrence of abscess. Attention should be called to the complication of intracranial tuberculosis, especially in cases worsened during anti-tuberculous chemotherapy.
