Abstract

A study was conducted to characterize cephalic lesions found in patients with neurotoxoplasmosis associated to HIV/AIDS. The sample was composed of 53 patients who were referred to «Hermanos Ameijeiras» Hospital to undergo neuroimaging studies. Sociodemographic, clinical, anatomical and imaging variables were used to characterize, compare and group the lesions according to presentation patterns and to issue an imaging diagnostic impression. Neurotoxoplasmosis affected 30 cases (56 %), with multiple lesions in 21 patients (70 %). The most frequent anatomic locations were the basal nuclei, the thalamus and the parietal lobes. Presence of perilesional edema in the magnetic resonance imaging (MRI) was evidenced in the 100 % of the cases. The CT- scan was more sensible to identify cerebral calcifications. The 96.7 % of the cases presented contrast enhancement after IV contrast administration for the CT-scan. An imaging pattern of focal lesion with contrast enhancement is a key for the diagnosis of Neurotoxoplasmosis, generally confirmed with specific treatment response.
