Frontal meningioma may present solely withpsychological symptoms that resemble dementia. We present the case of a 42-year-old man who initially was thought to have dementia, but he was eventually diagnosed with dementia caused by a sphenoid wing meningioma. Diagnosis of this illness is often delayed due to the insidious nature of the symptoms, which may be mistaken as symptoms of dementia. As cognitive impairment is complex and easily overlooked, it is important to accurately assess neuropsychological function in patients with large brain tumors.
