Psychiatric symptoms caused by brain lesions are not uncommon nowadays, caused by several different pathologies such as Alzheimer's, dementia, vascular and oncological diseases, etc. and they are known as neuropsychiatric or neurobehavioral symptoms, overlapping as mental health disorders. The most common primary brain tumors are gliomas, and the most common neuropsychiatric symptoms caused by them are depression, anxiety disorder, schizophrenia-like psychosis, anorexia nervosa, or cognitive dysfunction. We present a case of a 46-year-old male with no psychiatric familial history who started with a schizophrenia-like psychosis with hallucinations and, in consequence, killed his mother, symptoms which, after almost eight years, were known to be caused by a brain tumor.
