Mania and psychosis associated with right parietal meningioma

Abstract

Objective

Meningioma is the most common type of primary central nervous system and intracranial tumor, and psychiatric changes attributed to meningioma include depression, apathy, psychosis, and personality changes. We present a case of a 59-year-old man with right parietal meningioma who developed mania with psychotic features throughout multiple hospitalizations.

Method

Single-case report.

Results

The patient originally presented with headache and bilateral lower extremity weakness. He was found to have a large medial sphenoidal wing meningioma and a small right parietal meningioma. The sphenoidal wing meningioma was removed via craniotomy, but the right parietal meningioma was not resected. In the following years, the patient developed symptoms of mania and psychosis which coincided with an increase in size of the right parietal meningioma.

Conclusions

Previous studies have linked right parietal meningioma to psychosis, but this case is one of the first to suggest that right parietal meningioma may be associated with the development of mania along with psychotic features.
