Schizophreniform psychosis in a patient with right temporal-parietal meningioma

We report the case of a 64-year-old woman with a right temporal-parietal meningioma. She presented initially with depressive symptoms but later developed symptoms of acute schizophreniform psychosis. The psychotic symptoms dissapeared after treatment with neuroleptics. The resection of the meningioma led to a lasting remission of the psychotic symptomatology without continued administration of neuroleptics. The correlation between psychotic symptoms and the results of CT scan or MRI is controversial. In this case, the evidence points towards an organic cause of the psychosis rather than an endogenous psychosis.
