title: Giant cerebellar tuberculoma mimicking a malignant tumour.
abstract: We present a patient with a giant cerebellar tuberculoma which MRI led us to believe was a vascular, malignant tumour. Angiography revealed the mass to be relatively avascular, but also showed marked narrowing of the posterior circulation vessels, suggesting arteritis. Biopsy of the lesion was reported as consistent with tuberculoma. We highlight the need to integrate different imaging modalities in arriving at a diagnosis of an intracranial mass and discuss atypical features of intracranial tuberculomas.
