Brain Tumor Presenting Mania Symptoms: A Case Report

Brain tumors manifest with neurological symptoms as a result of mass effects. Occasionally, brain tumors may manifest with an initial psychiatric presentation in the absence of neurological deficits or symptoms. We present a case of a 54-year-old woman who showed increased energy, elevated mood, delusions, and headache. Symptoms of psychosis and mania began about two months ago and have worsened over the past month. Neurological examinations are normal. MRI of the brain confirmed the tumor on the left frontal lobe. A craniotomy and tumor resection were performed and the final diagnosis was meningioma (meningotheliomatous, WHO grade I). However, manic symptoms have been documented to occur more frequently in right frontal tumors. Early neuroimaging and a high index of suspicion are crucial to avoid misdiagnosis and ensure timely treatment of brain tumors with psychiatric symptoms
