An intracranial aneurysm would be low on the differential diagnosis of a patient presenting with behavioral or emotional changes. Nonetheless, complex partial seizures (CPS) may cause such symptoms and result from an unruptured intracranial aneurysm. Failure to diagnose and treat this condition in a timely manner increases the patient's risk of catastrophic aneurysmal rupture. This report describes a 55-year-old woman who presented following two CPS which began with the perception of a strange smell and culminated in a brief loss of consciousness. She had no history of seizure disorder or recent trauma. Magnetic resonance imaging (MRI) revealed a space-occupying lesion over the right temporal lobe near the amygdala. Magnetic resonance angiography (MRA) confirmed a 1.5-cm right middle cerebral artery aneurysm, with a dome projecting toward the amygdalohippocampal region. Following surgical ablation, the patient's CPS were well controlled. A review of the literature is performed on this unusual etiology and management strategies are discussed.
