Primary and secondary brain tumors can be neurologically silent for a period of time and may present with psychiatric disorders symptoms. Patients can present with depression, mania, psychosis, anxiety, apathy/abulia, cognitive or personality changes, and even anorexia. Several studies were done to classify symptoms of psychiatric disorder according to the site of the brain tumor. Despite the fact that organic brain lesions including brain tumors are frequently seen in patients with psychiatric disorder, it is unlikely to diagnose these brain lesions without the use of brain imaging techniques routinely by the psychiatrists. A thorough neurological evaluation is important to assist the diagnosis, the atypical presentation, previous history of body organ’s tumors, poor response to treatment, or waxing and waning of symptoms should lead to suspicions of organic etiology as the cause of psychiatric presentation. We present 42-year lady, a known case of operated left breast carcinoma diagnosed in 2004, presented with 6-weeks history of depressive symptoms to the psychiatric clinic and was diagnosed with Major Depressive Disorder. Four weeks later, she presented to the clinic with worsening of her depressive symptoms with change in personality, numbness in her left side and occasional headache. Neurosurgery consultation obtained and head CT and MRI showed right parieto-occipital lesion. She underwent right temporo-occipital craniotomy and resection of lesion. Her post-operative course was unremarkable.
