Background:
Mental disorders are a common finding among patients with unruptured intracranial aneurysms.
Case:
The current case concerns a young man with an anterior communicating artery aneurysm who was misdiagnosed with schizophrenia and bipolar disorder due to his significant psychosis and mood episodes. Having undergone surgery on the unruptured intracranial aneurysm, the patient's psychiatric symptoms disappeared, and he maintained a stable mood during the 3-year postoperative period.
Discussion:
The case is indicative of the need to consider the possibility of organic brain lesions in patients with first episodes of psychiatric presentations.
