We describe the case of a Nicaraguan patient suffering from Active Parenchymatous Neurocysticercosis, showing as major symptom a loss of visual acuity. Imaging studies, such as Computed Axial Tomography scans and Nuclear Magnetic Resonance, show lesions that suggest toxoplasmosis or cysticercosis. The diagnosis was confirmed by ELISA, demonstrating the presence of anticysticercus antibodies in cerebrospinal fluid. Results from other lab tests, such as cytochemical analysis of cerebrospinal fluid, hemogram, and blood biochemistry, were within normal range. Albenzadole (500 mg) was prescribed twice a day for a period of 30 days, together with anti-inflammatories and anticonvulsant drugs. Visual acuity did not improve after treatment
