title: Computerised tomography of intracranial tuberculomata.
abstract: The CT appearances of 14 tuberculomata are described. In 10 of these there is a similarity of appearance which may permit a definitive or high probability diagnosis. The features are: a mass lesion approximately isodense with brain substance surrounded by an intense unbroken ring of contrast enhancement. Calcification may be present within the ring giving a 'target sign'. Two of the other cases were 'tuberculomata en plaque' which had features similar to each other.
