We reported a case of non-herpetic acute encephalitis with unilateral temporal cortex lesion revealed by MR imaging and SPECT study. The patient was an eighteen years old woman who developed tonic-clonic seizure after common cold symptom. She was healthy before this episode. ⋯ The encephalitis presenting unilateral temporal cortex lesion without the infection of herpes simplex virus is thought to be very rare. Our case was distinguished from non-herpetic acute limbic encephalitis by an extent of the lesion and clinical manifestations. MR FLAIR image was useful for the detection of the lesion in this case.
