Other encephalitis and encephalomyelitis [G04.81], Reason for Study: ^Reason: evaluate for worsening vs improvement of autoimmune encephalitis; patient is on a tapering dose of steroids History: Headaches Redemonstration of right hippocampal head and amygdala volume loss, unchanged since prior scan.There is no evidence of abnormal enhancement on the scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
