Neurosurgical management of the acquired immunodeficiency syndrome. An update.
A retrospective review of a 24-month experience on the neurosurgical service at a large metropolitan hospital identified 33 patients with the acquired immunodeficiency syndrome (AIDS) who underwent diagnostic or therapeutic procedures. Intracranial mass lesions unresponsive to empiric medical therapy for presumed Toxoplasma gondii encephalitis underwent diagnostic biopsy in 22 patients: primary lymphoma was identified in 10 (45%) of these patients, and biopsy led to a treatable diagnosis in 16 of the 22. Patients with lymphoma were significantly more likely to have a single mass lesion than those with other diagnoses. The remaining 11 patients had a wide variety of neurologic disorders, including multiple strokes and transverse myelitis, aspergillous fungal infection of the base of the skull, primary lymphoma of the spinal cord, cat-scratch fever of the spine causing painful radiculopathy, hydrocephalus associated with cryptococcal meningitis, and progressive inflammatory peripheral neuropathy. Two patients had lymphoma within the subarachnoid space. Three patients with well-controlled AIDS underwent elective neurosurgical therapy for intractable radiculopathies due to herniated lumbar discs in 2 and cervical spondylosis in 1. Current treatment strategies in AIDS appear to have limited the need for brain biopsy, but the spectrum of neurologic disorders has broadened, requiring continued participation by neurologists and neurosurgeons. With improved long-term survival, the elective treatment of non-AIDS-related neurologic disorders in selected patients may be appropriate.
