Cytologic evaluation of the CSF is often difficult when trying to distinguish between truly neoplastic and reactive cells. Several non-neoplastic conditions may be associated with atypical cells in the CSF, a fact the clinician has to consider to avoid inadequate aggressive theraphies. We report here three patients with infectious meningitis (due to Herpes zoster virus in two, and neuroborreliosis in one) and cytologically atypical cerebrospinal fluid lymphocytes. Further characterization showed that the pleocyrosis in these patients was of reactive origin. Cytomorphology is frequently insufficient and histochemical, immuncytochemical and cellular genome analysis techniques may help differentiate atypical reactive cells from neoplastic cells.
RESUMEN
This is a report of a patient who developed thoracic cystic myelopathy immediately following an otherwise successful decompression operation for spondylotic stenosis secondary to osteophyte formation of the thoracic spinal canal. As this case shows, thoracic laminectomy is not without risks, and cystic myelopathy is a potential complication that should be borne in mind when surgery for spondylosis is being planned. Cavitation of the spinal cord may be associated with trauma secondary to extramedullary cord compression.

The objective of this study was to characterize the cognitive status of a population of asymptomatic HIV-positive drug addicts (patient group) to document the relationship between neuropsychological results and cerebral blood flow defects as measured by single photon emission computed tomography. As a control group we employed an age-matched population of HIV-seronegative drug addicts. Some neuropsychological differences were found between patients and controls and between drug addicts and normal population. We could not detect any difference in cerebral blood flow rates among HIV-1-positive and -negative drug addicts.
