AIDS-related primary central nervous system lymphoma: prolonged remission associated with highly active antiretroviral therapy.

ABSTRACT

A 36-year-old HIV-seropositive man developed progressive confusion and unilateral tremor of the hand. His medical history included cryptococcal meningitis and CMV colitis. CT scan revealed a single hyperdense mass with minimal peripheral enhancement at the region of the cerebral peduncle and pons, causing obstructive hydrocephalus. He was treated with ventriculo-peritoneal shunt and cranial radiotherapy. He also received treatment with highly active antiretroviral therapy (HAART). A CD4+ cell count was increased from 2 to 345 cells/mm3. He returned to normal function for about 32 months after treatment.
