Evaluation of Brain Lesions

Infections that primarily cause meningitis (eg, tuberculosis and cryptococcosis) may also cause focal parenchymal brain lesions, usually extending from the cisternal and sulcal CSF spaces. Using an algorithm (Figure), supplemented by serologic studies and PCR, the diagnosis is usually established[58]; however, brain biopsy may be needed. Due to the occurrence of coagulation disorders and poor immune response of HIV-positive patients, neurosurgical intervention is poorly tolerated and should be avoided if possible.
