Epileptic Capgras-Like Delusions in a Patient with Right Frontal Meningioma: Case Report

Capgras syndrome is a condition characterized by the belief that a relative has been replaced by an almost identical imposter. The disorder has been reported in several neurological diseases. We describe the uncommon case of a transient Capgras syndrome manifesting as focal temporal seizures in a woman with a right frontal meningioma. Our patient represents an exceptional case of Capgras syndrome for several reasons, namely, the association with meningioma, very rarely reported before, the transient manifestation of symptoms, and, most importantly, the epileptic etiology of reduplicative paramnesias. Lastly, our report also confirms the importance of frontal and right hemisphere dysfunction in generating Capgras syndrome-like delusions.
