BACKGROUND Neuropsychiatric sequelae are common in primary and secondary brain tumors, with symptoms varying as a function of tumor type, location, and size. OBJECTIVE The author presents a case of a 49-year-old woman with melanoma metastatic to the brain, in an effort to link lesions and complex olfactory and visual hallucinations. METHOD The patient's history and clinical diagnostic procedures are presented. RESULTS A computerized tomographic scan showed lesions in the right parietal lobe, bilateral ring enhancing lesions, an enhancing lesion in the frontal lobes, and another lesion in the left temporal lobe. DISCUSSION The author discusses possible causal connections among lesions found and various complex symptoms.
