A 31-year-old male patient was hospitalized in our hospital due to the compulsory treatment desicion of the related court because of the guilt of ?murder?. The patient had been treated in intensive care unit due to head trauma because of a traffic accident, in 2001. The patient had had no complaints or disease until this accident. After his treatment for head trauma, psychotic signs as persecution delusions had appeared. He had killed his aunt because of his persecution delusions as he believed his aunt had been hostile to and would harm him. In his cranial MRI, thinning-atrophy in all parts of corpus callosum was observed. He was diagnosed with ?psychotic disorder due to head trauma, with delusions?, according to DSM-IV TR. This case is found interesting because of the time relation between head trauma and psychosis and corpus callosum atrophy detected after the head trauma.
