ABSTRACT
OBJECTIVE: The aim of this study was to identify the main neurological conditions associated with HIV/AIDS in Mexican patients treated at the National Institute of Neurology and Neurosurgery (NINN) in Mexico city, the main referral center for patients with disorders of the central and peripheral nervous system. METHODS: An observational, transversal and descriptive analysis was performed. We reviewed the databases from the Department of Epidemiology and the medical records of patients with AIDS seen during the period from January 1st, 1995 to December 31, 2009. RESULTS: 320 patients were detected, the main conditions related to HIV/AIDS were brain toxoplasmosis (42%), cerebral criptoccocosis (28%), tuberculous meningitis (8.7%), linfoma no Hodking (3.75%), acute HIV infection (3.4%) and AIDS dementia complex (3%). No specific trend on morbility and mortality were detected during the period of study. CONCLUSIONS: In Mexico the most common neurological complications of HIV/AIDS are opportunistic infections.

OBJECTIVE AND IMPORTANCE: We report an unusual case of basal ganglia granulomas caused by Candida albicans that surrounded the proximal segment of a nonfunctional cerebrospinal fluid shunt in a previously healthy patient. CLINICAL PRESENTATION: A 22-year-old woman had undergone ventriculoatrial cerebrospinal fluid shunt placement for posttraumatic hydrocephalus 3 years previously. One year later, a shunt revision was followed by wound dehiscence with local infection at the neck level. She received oral administration of antibiotics for 3 months until the wound closed. Twelve weeks before admission, the patient experienced pulmonary emboli. She received anticoagulants, and the distal segment of the shunt was removed. Five weeks after shunt removal, she presented with headache and left-sided hemiplegia caused by right basal ganglia inflammatory masses. INTERVENTION: A stereotactic brain biopsy was performed, and the shunt remnants were removed. Microscopically, the lesions were acutely and chronically inflamed. C. albicans grew in tissue and in shunt hardware cultures. The patient was treated with 1.1 g of intravenously administered amphotericin B and orally administered ketoconazole; she recovered completely. CONCLUSION: C. albicans brain granulomas occur rarely in immunocompetent patients. Despite the large size of the lesions and severe brain edema, the absence of an underlying disease contributed to complete resolution after shunt removal and antifungal therapy.
