title: [A case of calcified intracranial tuberculoma presenting unique MRI findings].
abstract: A 41-year-old male patient was admitted in our Ryukyu University Hospital complaining of parosmia. He had a history of miliary tuberculosis 21 years ago. Neurologically he showed left anosmia and hyperreflexia of the right upper extremity. Plain skull X-P and CT scan revealed a calcified mass, 25mm in diameter, at the left frontal base. In MRI, the mass showed isointensity using the T1 weighted inversion recovery sequence and heterogenously low intensity using the T2 weighted spin echo sequence. Surgery was performed by bifrontal craniotomy. Then the tumor was removed totally including two coexisting small tumors. Histologically, they consisted of calcified caseous tissue and thick collagen capsule, suggesting old calcified tuberculomas. Postoperative course was uneventful and did not result in meningitis. Antituberculous therapy of streptomycin, isoniazid and rifampin was given for 2 weeks, started on the operative day. MRI findings were presented in detail and the guideline of antituberculous therapy to the tuberculoma was discussed.
