Neuro-cysticercosis presenting with single delusion: A rare psychiatric manifestation

We report a case of multiple parenchymal neurocysticercosis in an elderly lady without raised intracranial tension which caused diagnostic confusion. The initial manifestation was only psychological as delusional disorder without any neurological symptoms or focal neurological deficit. Plain computed tomography scan showed mild bilateral periventricular and subcortical hypodensities. The development of hemiplegia during the course of psychiatric treatment prompted us to go for magnetic resonance imaging brain which clinched the diagnosis.
