Relapse of herpes simplex virus (HSV) encephalitis rarely occurs after acyclovir treatment. We experienced a case of relapsing HSV encephalitis in the contralateral temporal lobe, resulting in Kluver-Bucy syndrome, after a full dose acyclovir treatment. Sudden behavioral and emotional changes after HSV encephalitis treatment suggest relapsing HSV encephalitis as well as temporal lobe epilepsy.

Kluver-Bucy syndrome is defined as a rare neurobehavioral disorder with hyperphagia, hyperorality, hypersexuality, and visual agnosia. This syndrome is usually resulting from bilateral lesions of the anterior temporal lobe including amygdala. Although it could occur after various diseases, stroke is uncommon etiology. We report a patient with Kluver-Bucy syndrome due to bilateral posterior cerebral artery territory infarction.

Bilateral anterior opercular syndrome and partial Kluver-Bucy syndrome are associated with bilateral middle cerebral artery lesions. The combination of these two syndromes has only been reported in a child with limbic encephalitis. In this case, a 44-year-old woman with bilateral middle cerebral artery infarction, which occurred 2 years prior, could walk independently. However, she showed automatic-voluntary dissociation and anarthria with preserved writing skills. She also presented hypersexuality, hypermetamorphosis, and memory disturbances. Here, we report a case of an adult stroke patient who suffered from bilateral anterior opercular syndrome accompanied by partial Kluver-Bucy syndrome.

Kluver-Bucy Syndrome (KBS) is consisting of hyperorality, emotional blunting, hypersexuality, altered dietary habits, visual and auditory agnosia. It has been reported in variable neurological diseases. However, only a few cases reported in epilepsy. We report a patient with unilateral temporal lobe epilepsy who presents transient hyperorality during seizure. A 46-year-old man has complex partial seizures which were abdominal aura followed by hyperorality and hand automatisms. Hyperorality was characterized by putting patient's hand or seizure button into his mouth. Brain MRI demonstrated right hippocampal sclerosis. The interictal and ictal SPECT suggested right temporal lobe dysfunction, and PET showed bitemporal hypometabolism. Rhythmic ictal activities were arising from right temporal region when patient presented hyperorality. We speculate that transient hyperorality in this patient could be a symptom of KBS. This case suggests that transient KBS can be occurred in a unilateral temporal lobe epilepsy when ictal discharges cause bitemporal dysfunction during temporal lobe seizure.

BACKGROUND AND SIGNIFICANCE: Frontotemporal dementia is a behavioral disorder arising from nonAlzheimer's disease atrophy of frontal and anterior temporal lobe. Clinical manifestations include frontal lobe dysfunction. Kluver-Bucy syndrome or progressive language impairments. Two types of histological change underline, the atrophy. The commoner pathology is nerve cell loss and spongiform change with astrocytic gliosis. The second one is typical Pick-type histology characterized by intraneuronal inclusion body and astrocytic gliosis. We report a case with biopsy proved Pick's disease presenting with progressive nonfluent speech. CASE: A 41-years, old right-handed woman developed progressive language impairment over a period of 6 months. Brain MRI revealed asymmetric frontotemporal cortical atrophy more severe on the left side and 18F-FDG-brain, PET showed hypometabolism in the same area. Neuropsychological test including Korean version-Western Aphasia Battery revealed non-fluent speech as well as frontal lobe, dysfunction. A biopsy from left frontal lobe, demonstrate neuronal loss and diffuse astrogliosis. In the cytoplasm of remaining neurons are eosinophilic inclusion bodies which are neurofilament-positive with immunostaining. Senile plaque, neurofibrillary tangle and cortical Lewy body were absent. COMMENT: We report a case presenting with progressive nonfluent speech whose imaging and pathological findings are compatible with Pick's disease, which may be the first biopsy proven case in Korea.
