Reduplicative paramnesia (RP) is a well recognized neurological phenomenon, characterized by a false belief that a familiar person or place has been duplicated. In the development of RP, right‐dominant frontal lesions are commonly observed. We report a 73‐year‐old woman who developed reduplication of people and places 3 months after the surgical removal of a large right frontotemporal meningioma. About 1 year after the surgery, her RP diminished after a small dose of risperidone. Neuropsychological evaluation was performed before surgery, after surgery when RP was present and again after recovery of RP. In accordance with the literature, the present case study suggests that a right hemispheric lesion is the essential neuroanatomical substrate in the development of RP. However, no single neuropsychological factor can fully explain the development and resolution of RP. Multiple factors, including neuroanatomical, cognitive and environmental factors seem to be dynamically involved.
