Large intracranial supratentorial tuberculoma imitating as a malignant lesion: a case report

Abstract

Abstract Background CNS TB roughly correlates to 1–10% of all intracranial tumors. The spectrum of CNS-TB is wide and can present as tuberculous meningitis, tubercular abscess, tuberculoma, or hypertrophic pachymeningitis. Tuberculomas are usually located at the corticomedullary junction and periventricular region, as expected for hematogenous dissemination. They are mostly infratentorial in children and supratentorial in adults. They may present months to years after infection. Observations Here we have a 55-year-old female who presented with a history of headaches, sudden loss of consciousness, and seizures. Initial imaging showed a right parietal mass lesion appearing to be malignant on initial imaging which had a significant mass effect and midline shift. The patient was operated on for the same and histopathology showed chronic granulomatous lesion and tissue staining s/o tuberculosis. Lessons So a diagnostic option for infective etiology should be kept even for an intracranial supratentorial mass lesion.
