In the frontal lobes, meningioma
Presses on, slowly grows in its stroma.
Meningioma is a not-uncommon slowly growing benign tumor within the cranium. Pressure on adjacent portions of normal brain induce neurological symptoms. When the tumor is located in the frontal cortex, neuropsychiatric manifestations may include bizarre thoughts, frequently paranoid, and unrepressed behavior. Fortunately, the tumors, when suspected, are readily diagnosed on neuro-imaging studies, and surgical therapy is often curative.
Brain tumours account for only a small portion of patients suffering such neuropsychiatric symptoms; however, medical practitioners frequently hope that such a correctable cause may be discovered.
