Cysticercosis mimicking brain tumor: the role of albendazole as a diagnostic tool.

We report a patient with seizures and a single ringlike enhancing lesion on MRI that resembled a low-grade glioma. The patient received a diagnostic trial with albendazole on the assumption that this lesion could be a cysticercus. Follow-up showed resolution of the brain lesion in 4 weeks. Albendazole administration to patients with single ringlike enhancing lesions may obviate unnecessary surgical procedures in selected cases.
