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.

The authors report on the results of clinical investigations, treatment and follow-up of a 9-year old boy with complex partial status epilepticus (CPSE) which occurred after the first onset of partial secondary generalized epileptic seizures. Electroencephalografic recordings during status epilepticus showed a diffuse, generalized, high-voltage delta dysfunction and bilateral epileptiform activity, with local maximum over the posterior right temporal parietal regions. Parenteral administration of diazepam, phenytoin and phenobarbitone as choice anticonvulsant drugs, failed to stop CPSE in the patient. Only by continuous intravenous infusion of chlormethiazole (Heminevrin) status epilepticus was successfully controlled. Paroxysmal discharges on electroencephalogram disappeared and attenuation of slow wave activity was evident. Memory deficits and the elements of nominal dysphasia and tactile dysgnosia were apparent soon after cessation of CPSE and may be related to the signs of maximal local electroencephalographic dysfunction. Later testings after complete seizure control by chlormethiazole and phenytoin given orally, showed almost normal results. No side effects were encountered. A more common chlormethiazole administration as a useful therapeutic agent in the management of CPSE especially in children with refractory and long-time status, would be mandatory. Since chlormethiazole is free from serious side effects, its earlier use in the control of epileptic status may help to preclude some severe cognitive effects and to evade the use of barbiturate anesthesia as the last therapeutic resort.

Thirty-seven consecutive adults and 2 children with tuberculosis of the nervous system were studied. Twenty-eight patients (72%) had intracranial or intraspinal tuberculomas and only 11 patients (28%) had tuberculous meningitis. Of the 14 patients (36%) with intracranial tuberculomas 6 presented with epilepsy of late onset including convulsive status epilepticus(2). The 6 patients with multiple tuberculomas some of which were situated in the infratentorial compartment were surprisingly free of major neurological disability of systemic disturbance. Thirteen patients (33%) presented with spinal cord compression due to tuberculoma. Eight of these had associated bony abnormalities such as collapsed vertebrae and loss of pedicles usually regarded as characteristic of malignant disease and 2 presented with clinical features of acute transverse myelitis. Eleven patients (28%) had tuberculous meningitis. One of these died, 1 had a protracted illness with gait ataxia and hydrocephalus and 1 other patient was disabled by hemiplegia, dysphasia and epilepsy but the remaining 8 recovered fully. Tuberculosis outside the nervous system was found in 13 patients (33%) in 12 (31%) of whom it was pulmonary. Acid fast bacilli were demonstrated by Ziehl-Neelsen stain in 16 patients (52%) out of 31 from whom specimens were available. Mycobacterium tuberculosis was eventually cultured from only 6 specimens. These data suggest that the clinical and radiological features of tuberculosis of the nervous system in Saudi Arabia may differ substantially from those reported from other countries. In our study there was low morbidity and low fatality rate. Two patients had infratentorial tuberculomas, and 8 patients had bony abnormalities in the vertebral column, typical of malignant disease.

Three patients are described who developed cerebral complications and an EEG abnormality for several days after metrizamide myelography. Clinically, the patients showed a fluctuating confusional state with dysphasia and retrograde amnesia, while their EEGs were dominated by runs of slow wave activity interspersed with frequent spikes. The runs appeared either continuously or in paroxysmal bursts. The clinical symptoms and the EEG are compatible with complex partial status epilepticus and are similar to the symptomatology of ten patients described in the literature. This rare clinical entity should be distinguished from a more common complication of metrizamide--non-specific slow wave abnormality of variable degree in the EEG with or without clinical signs. Clinical manifestations may include transient aphasia and weakness of the limbs with pyramidal signs.

A right-handed 32-year-old woman had recurrent combined partial temporal and secondary generalized epileptic states almost constantly related to menstruations. During such more or less prolonged episodes sometimes the patient presented right adversive attacks with short postictal dysphasia. The catamenial status epilepticus observed in this cas was manifested in two clear-cut behavioral phases. The first phase was characterized by frequently recurrent left temporal epileptiform discharges without tendency to diffusion, progressively more prolonged and pseudorhythmic associated with a signalized feeling of intense fear without apparent impairment of consciousness or speech disturbances. The electroclinical features of the first phase suggest a depth origin of the paroxysms, probably due to a primary epileptogenic focus in the left amygdaloid-hippocampal complex. In the second phase the left temporal focal semirhythmic discharges associated with fear bouts became more frequent and prolonged and began to be followed by long-lasting generalized discharges resulting in a trance-like state with severe impairment of consciousness. The diffuse paroxysmal activity regularly preceded by the left temporal focal discharges was interpreted as a form of secondary bilateral synchrony constantly triggered from a focal pacemaker represented by the primary epileptogenic focus. During the very short transient periods of sudden cessation of the epileptiform activity the patient returned immediately to an apparent normal mental state. Good correlation could be established between different seizure patterns and predominant clinical signs. Intravenous diazepam rapidly decreased and then completely stopped the catamenial status epilepticus. Some problems related to the classification of these rare epileptic events are discussed.

Status epilepticus is usually a straightforward diagnosis when a patient has two or more seizures without regaining consciousness. However, when status is non-convulsive and, in particular, has a temporal lobe flavour the clinical presentation may be misleading. Presentation with automatic or psychic behaviour is well recorded. We report a patient with nonconvulsive status who presented with progressive dysphasia with widespread CT and MRI changes. The dysphasia and imaging changes led to a diagnosis of a probable neoplastic brain process but reversed with anticonvulsant treatment.

We describe a 77-year-old woman who developed a confusional state, cognitive impairment, behavioural abnormalities and dysphasia after treatment of hypercalcaemia. Repeated EEG recording revealed rhythmic sharp-wave activity over the right parietal-occipital lobe. Magnetic resonance imaging (MRI) showed marked hyperintense signal changes bilaterally. The diagnosis of a non-convulsive status epilepticus (NCSE) was made. With antiepileptic treatment the patient improved and MRI as well as EEG changes were almost all reversible. NCSE is an important differential diagnosis of patients with neuropsychiatric symptoms and can develop after rapid lowering of serum calcium levels in hypercalcaemia.

We report the long-term follow-up of an elderly patient who developed a permanent sensorimotor dysphasia after status epilepticus. Magnetic resonance imaging of the brain and magnetic resonance angiography failed to demonstrate structural cerebral damage; however, a fluorodeoxyglucose positron emission tomography scan revealed marked hypometabolism involving a large area in the left hemisphere and contralateral cerebellar cortex. Our case illustrates that permanent language dysfunction may occur after recurrent complex partial and secondarily generalized seizures.

Seizures and focal neurologic deficits may be the complications of neurosyphilis, but status epilepticus as a presenting picture of neurosyphilis is rare. We describe a 41-year-old man with an acute onset of expressive dysphasia, followed by persistent seizure state and severe complications of systemic medical problems. An extensive laboratory evaluation confirmed the diagnosis of neurosyphilis and diabetes mellitus. Brain magnetic resonance imaging showed edematous change in the left cingulate gyrus, left temporal lobe, and peri-Rolandic area, which suggested an inflammatory process. Due to varied clinical manifestations of neurosyphilis, we underscore the importance of considering neurosyphilis among the possible causes of status epilepticus and any central nervous system diseases.

The goal of this report is to review periodic lateralized epileptiform discharges (PLEDs), particularly their associated symptoms, the possibility that the pattern represents a focal status epilepticus, and finally the usefulness of antiepileptic drugs (AEDs). The associated symptoms often include an "altered state of consciousness" or "confusional state," but also more specific symptoms have been noted, such as nystagmus retractorius, cortical blindness, depression, apraxia, amnesia, hemianopsia, hemiparesis, gaze preference or deviation, dysphasia, and speech impediment. PLEDs have often been referred to as an ictal pattern, and many investigators have viewed the condition an example of subclinical status epilepticus. The intense hypermetabolism and increased blood flow revealed by PET and SPECT scans have been considered to support the ictal nature of this waveform. Although the pattern is difficult to treat, the AEDs that have been reported as successful include carbamazepine, midazolam, pentobarbital, sodium valproate, and felbamate. As only subtle symptoms are, at times, present and therefore may be missed and the pattern is known to be difficult to treat, epileptologists who view the PLED pattern as only an EEG curiosity and decide against treatment may wish to reevaluate the electroclinical evidence related to this interesting and significant pattern.
