Brain abscess: an atypical CT appearance of CNS tuberculosis.

Brain abscess is an extremely rare manifestation of tuberculous involvement of the CNS; meningitis and tuberculoma are much more common [1-6]. The CT appearance of tuberculous abscess cannot be distinguished from many other entities that can present as a ring-enhancing lesion, such as pyogenic abscess, primary or metastatic neoplasm, or resolving hematoma. However, given the appropriate history one can suggest the correct diagnosis. We present an unusual case in which there was coexistence of supratentorial tuberculomas with an infratentorial tuberculous abscess.
