CT features of cerebral tuberculoma and tuberculous abscess. a The right frontal tuberculoma typically shows an isodense centre to cortex, rim enhancement and surrounding oedema. This is the most common appearance of focal tuberculous lesions of the brain. b A variable pattern of enhancement of tuberculoma may be the result of different amounts of central necrosis. This patient who presumably has very little necrosis in the centre of a tuberculoma shows ‘discoid’ or ‘nodular’ enhancement with surrounding oedema. c The tuberculous abscess, which represents less than 5% of all focal cerebral tuberculous lesions, characteristically demonstrates a low-density centre with rim enhancement and surrounding oedema. d A TB abscess in this patient should be distinguished from a tuberculoma because it is larger than 2 cm in size and has a low-density centre. It is indistinguishable from a pyogenic abscess. Lack of a soft-tissue nodule/component differentiates this from most neoplasms
