Meningiomas are the most common type of primary tumor of the central nervous system. The signs and symptoms of meningioma are dependent on the location of the tumor. Psychiatric symptoms can range from mood symptoms, anxiety, psychosis features, memory problems, and personality changes, and are usually related to the location of the meningioma tumor. Here we report a middle-aged lady with psychotic symptoms after resection of left petrous meningioma which lead to significant socio-personal dysfunction. She started treatment with antipsychotics. At 3 months of follow-up, the patient had no ideas of persecution or reference, had occasional hallucinations, and had a fair insight.
