A 51-year-old housewife developed symptoms of a cold followed by high fever, delirium, coma, rigidity of extremity muscles, positive Babinski sign and generalized convulsions, while complement-fixing antibody titre to herpes simplex virus in the sera raised over 128 X and declined to 8 X in the course. She finally expired of bronchopneumonia following status epilepticus after 94 days of illness. Severe necrosis with extensive hemorrhage in the white matter was predominant in the temporal, insular and orbitofrontal cortex, thalamus and globus pallidus. Focal rarefaction of the cerebral cortex with a very few eosinophilic intranuclear inclusions in the oligodendroglia and nerve cells, nerve cell destruction in the substantia nigra with glial nodules and perivascular inflammatory cell cuffs were observed. Abundant cytomegalic inclusion cells, originating from hypertrophic astrocytes, were present in the necrotic areas of cerebrum as well as in the rarefied tissue in the subependymal layers of the brainstem and cerebellum. Electron-microscopic study of the cytomegalic cells demonstrated the presence of numerous virions in both nucleus and cytoplasm. Fortuitour infection of the brain by cytomegalovirus with necrotizing encephalitis by herpes simplex virus is unique. The cause of double viral infections and severe lesions by less virulent strains is discussed.

A 62-year-old woman developed neurologic deficits 7 months after pulmonary lobectomy for alveolar cell carcinoma of the lung. CT scan of the head demonstrated two metastases with marked peritumoral edema. Administration of Decadron, chemotherapy and 3,000 rad cranial radiation resulted in dramatic improvement of dysphasia and right hand paresis. Almost 2 months later, rhythmic, involuntary movements of the left hand developed. There was progression to multifocal seizures, grand mal seizures, postictal depression, status epilepticus, and coma, with death 9 days after onset of the movement disorder. Bronchoalveolar carcinoma was widely disseminated in lungs and bones, and as three metastases in brain. Bland "ischemic" necrosis in a pseudolaminar pattern was present in the neocortex. Innumerable Cowdry type A intranuclear inclusion bodies were seen in neurons, astrocytes, and oligodenodroglia. Immunofluorescence demonstrated Herpes simplex virus type 2 antigen and electron microscopy revealed virions with the morphology of the Herpes group. The case is significant for (1) the concurrence of intracranial metastases and Herpes simplex encephalitis, and (2) the causal agent, Herpes simplex virus type 2. The implication for the clinical neurocientist is the potential in a patient with systemic cancer, for the causation of neurologic complications by more than one factor or mechanism.

A 70 year-old-man with recurrent herpetic keratitis had a meningo-encephalitis with transient left hemiplegia and disorders of consciousness. EEG disclosed periodic slow waves on the right temporal region. Isotope and CT scans showed focal abnormalities in the same region. Antibodies to herpes simplex virus were demonstrated by complement fixation in serum and specific antiherpes IgG and IgM by immunofluorescence assay in serum and CSF. A year later the patient had a status epilepticus. CT scan showed a large right temporal hypodense area. CSF was abnormal with pleiocytosis, increased protein and IgG levels. High titers of antiherpes IgG persisted in serum and CSF. Neuropsychological tests did not demonstrate any memory impairment. The occurrence of persistent inflammation after herpes simplex encephalitis is discussed. The unusual benign course without antiviral therapy, may be related to the reactivation of a latent infection with an efficient immunological response. The unilateral temporal necrosis may explain the absence of amnestic sequelae.

A case of viral encephalitis is described. A 55-year-old female developed hyperthermia and status epilepticus. Herpes simplex virus was regarded as a factor since viral complex titres were elevated and decreased. In addition to acyclovir and anticonvulsive agents, dantrolene (150 mg/day) was administered orally through a nasogastric tube for heat stroke. Convulsions and hyperthermia gradually decreased and intravenous agents were replaced by oral agents. Dantrolene may be a useful adjuvant in hyperthermia and convulsions associated with encephalitis.

Reversible bilateral lesions of the claustrum and external capsule in a 12-year-old girl suffering from a severe, transitory encephalopathy are reported. After a prodromal stage of feeling uncomfortable a sudden onset of status epilepticus occurred, followed by recurrent complex partial and myoclonic seizures for 3 weeks, with psychotic symptoms and temporary loss of vision, speech and hearing. After treatment with phenytoin the patient became free of seizures and recovered completely without neurological deficit. The initial cranial CT was normal; however, cranial MRI 7 days later showed bilateral selective lesions of the claustrum and external capsule, which disappeared completely 5 weeks later. The aetiology of these lesions remains obscure; repeated cerebrospinal fluid and blood tests were negative for herpes simplex virus and other infectious agents. The clinical and radiological improvement were concomitant. This may indicate a functional disturbance of the claustrum grey matter, rather than lesions of the white matter of the external and extreme capsules.

This report concerns two patients with fulminant meningoencephalitis presenting in status epilepticus with periodic lateralised epileptiform discharges (PLEDs) observed on electroencephalogram. The titer of herpes simplex virus type 1 antibody was not elevated in either serum or cerebrospinal fluid, and acyclovir was not effective for either patient. Corticosteroid therapy was dramatically effective, however, suggesting that autoimmune inflammatory diseases were the underlying systemic disorders. PLEDs can thus be associated with steroid-responsive inflammatory meningoencephalitis.

A 18-year-old man was diagnosed as having measles on the basis of cutaneous and mucosal eruption and high grade fever on May 10, 2001. Six days after the skin eruption, the patient developed general convulsion (day1). He was admitted to our hospital because of status epilepticus. We made a diagnosis of acute measles encephalitis, based on the clinical features and pleocytosis with an increase in protein in the cerebrospinal fluid. Under artificial ventilation and sedation, he received intravenous immunoglobulin and dexamethasone. Electroencephalography (EEG) on day 4 revealed periodic synchronous discharge (PSD). Significant elevation of antibody titer for measles virus was found in the serum, but not in the cerebrospinal fluid. Polymerase chain reaction method did not show viral genes of measles virus, herpes simplex virus and herpes zoster virus. Serial EEG studies demonstrated a decrease in PSD, followed by irregular spike-wave complexes within 20 days. He recovered completely one month after the onset. It should be kept in mind that PSD can emerge on EEG in the early stage of acute measles encephalitis.

This case is reported to raise awareness of herpes simplex encephalitis as a persisting brain disorder. A 66 year old immunocompetent man developed status epilepticus and died of pneumonia in the course of progressive hemiparesis, cognitive decline, and atrophy of the brain over a five year period after herpes simplex encephalitis. In addition to a completely destroyed left temporal lobe, necropsy revealed active encephalitis consisting of necrosis and lymphocyte infiltration with a large number of intranuclear inclusions in the neurones and glial cells in the markedly oedematous parenchyma of the right frontal and parietal lobes. Herpes simplex virus type 1 (HSV-1) antigen was detected by immunohistochemistry, HSV-1 DNA by in situ hybridisation, and herpes simplex virus nucleocapsids by electronmicroscopy. These clinical and pathological findings suggest that direct viral reactivation might result in a relapse of herpes simplex encephalitis, causing progressive clinical deterioration associated with the persistence of HSV-1 in the brain. This is the first case report demonstrating HSV-1 antigen, HSV-1 DNA, and herpes simplex virus nucleocapsids in a case of relapsing herpes simplex encephalitis.

The characteristic features of Kluver-Bucy syndrome include hypersexuality, hyperorality, placidity, hypermetamorphosis, visual agnosia, changes in dietary habits, and memory impairment. Human cases have been reported with herpes simplex encephalitis, head injury, Pick's disease, transtentorial herniation, adrenoleukodystrophy, and Reye's syndrome, all involving bilateral temporal lobe pathology. We present the case of a patient with no evidence of a structural lesion in the temporal lobes and behavioral changes consistent with Kluver-Bucy syndrome following complex partial status epilepticus.

The goal of this study was to clarify the clinical characteristics and prognostic factors of childhood postencephalitic epilepsy. Forty-four patients (20 boys and 24 girls; age range 21 months to 17 years, mean age 8.1 +/- 4.6 years) with postencephalitic epilepsy were selected from the 798 epileptic children treated and followed up at our hospital between 1993 and 2003. The clinical data included clinical features, electroencephalograms (EEGs), and neuroimages, all reviewed and analyzed retrospectively. Based on their post-treatment seizure outcomes, the children were divided into favorable (n = 20) and poor outcome groups (n = 24). Between the two groups, the age at encephalitis, cerebrospinal fluid findings, and seizure type were comparable. Factors indicating a poor prognosis for these patients during the acute phase of encephalitis were (1) status epilepticus occurring as the first seizure (P < .005), (2) slow background activity (P < .001) and multifocal spike discharges on EEGs (P < .01), and (3) herpes simplex viral encephalitis (P < .01). Our findings indicated that patients with status epilepticus and multifocal spikes on EEG during acute encephalitis have an increased risk of developing intractable epilepsy. To improve the outcome of postencephalitic epilepsy, intervention must occur earlier in the encephalitis stage.
