Abstract

Injury to the limbic system can result in amnesia, language difficulties, behavioral abnormalities, and psychological disorders. We present a patient who suffered psychosis related to disconnection of the limbic system after intraventricular and orbitofrontal hemorrhages following removal of a sellar meningioma. Diffusion tensor tractography was valuable for evaluating the structural integrity of the injured limbic tracts and determining the regeneration of tracts corresponding to neuropsychiatric recovery after cognitive rehabilitation.

Keywords: Diffusion tensor imaging; Intracranial hemorrhage; Limbic system; Psychosis.
