A patient is reported whose ailment meets the criteria of CPM. The illness was complicated by pneumonitis, most likely of the aspiration type. Of particular interest was the reversibility of a clinical picture of marked deterioration when attention was paid to fluid and electrolyte balance and maintenance of respiration. This patient's illness appears to meet the criteria of CPM, namely impairment of the facial muscles and tongue with dysphagia and dysarthria, flaccid quadriparesis or quadriplegia, and frequently, lack of response to painful stimuli followed by respiratory paralysis. The presence of peripheral neuropathy has been previously noted in a patient with CPM, but it is not an integral part of the disease.

A 38-year-old man developed pain and peripheral-type weakness on the right side of his face and was discovered to have decreased hearing bilaterally, as well as optic nerve swelling on the right. The pain and optic nerve swelling subsided over a period of six weeks, but hearing loss and facial weakness persisted. Thirty months later, he developed dysphagia, ataxia, dysarthria, nystagmus, and progressive spastic quadriparesis. He died approximately four years after the onset of the illness. Although no evidence of disease was found other than in the central nervous system during life, two nodules in the right lower lung were found on autopsy. The examination of these nodules, as well as the brain stem, showed an angiocentric and angionecrotic process with lymphoreticular and plasmacytoid invasion.

Eight patients with a homogeneous syndrome of progressive symmetric spinobulbar spasticity were studied. Clinical features were limited to those associated with dysfunction of the descending motor tracts and included spastic quadriparesis, pseudobulbar affect, spastic dysarthria, hyper-reflexia and bilateral Babinski signs. Lower motor neuron findings were absent and higher cognitive function preserved. Median age of onset was 50.5 yrs and median disease duration was 19 yrs. Neuropathologic features (including morphometric analysis) in the single autopsied case confirmed the selective involvement of the motor cortex. There was complete absence of Betz cells from layer 5 of the precentral cortex and the remaining pyramidal cells were significantly smaller than those seen in normal controls. Magnetic resonance imaging (MRI) revealed atrophy of the precentral gyrus and positron emission tomography (PET) scans showed diminished glucose [18F]fluorodeoxyglucose uptake in the pericentral cortex. Magnetic motor cortex stimulation revealed markedly prolonged central motor conduction times. The literature is reviewed and diagnostic criteria for primary lateral sclerosis based on clinical, laboratory and imaging features are proposed.

A 28-year-old woman developed central pontine myelinolysis (CPM) following severe hyponatremia. Radiological examinations demonstrated a characteristic pontine lesion of CPM. Her neurological symptoms (drowsiness, emotional lability, dysarthria, dysphagia, and quadriparesis) were improved dramatically by treatment with thyrotropin-releasing hormone (TRH) and rehabilitation. However, results of repeat computed tomographic (CT) scans of the brain remained unchanged. This case therefore suggests that TRH may be beneficial for the treatment of CPM, and that CT findings appear to be a limited prognostic indicator for CPM.

A 64-year-old hypertensive woman with hyponatremia due to acute gastroenteritis and the use of diuretics developed dysarthria, dysphagia, and quadriparesis 4 days after rapid correction of hyponatremia. The clinical course, electrodiagnosis (blink reflex) and cranial computed tomographic findings are compatible with an antemortem diagnosis of central pontine myelinolysis (CPM). CPM can be prevented by cautious correction of hyponatremia. Spontaneous recovery in this case contrasts sharply to the poor outcome in previously reported cases of CPM.

A case of traumatic occlusion of the bilateral vertebral arteries associated with fracture of the cervical spine is reported. A 34-year-old man, having no previously noted medical problems, fell to the bottom of a bathtub with a depth of 80 cm, and hit the vertex fronto-parietal region of his head. He was transferred to our hospital 6 hours after his fall with a crush fracture of the cervical spine at the C6 level. On admission he was alert, but having pain in the vertex region, dysarthria, blurred vision and hemiparesis. Roentgenograms confirmed a crush fracture of the C6 vertebral body. Computed tomograms of the brain revealed a high density of basilar artery. Cervical traction with a Halo brace was then carried out. Twelve hours after the trauma, left oculomotor and right facial palsy appeared followed by bilateral oculomotor palsy and respiratory difficulty. At the 14th hour, he displayed bilateral Babinski's signs and tetraparesis. Tetraparesis became complete with right-side Horner's syndrome at 16 hours. Cerebral arteriograms performed 20 hours after the trauma showed a complete occlusion of the right vertebral artery and an incomplete occlusion of the left vertebral artery at the C6-7 intervertebral disk space. Conscious level deteriorated to a 200 level on the Japan coma scale 28 hours after the trauma and to a 300 level after 32 hours. Computed tomograms revealed a marked low density on the cerebellum and brain stem 38 hours after the accident. He expired on the 22nd day after the trauma.(ABSTRACT TRUNCATED AT 250 WORDS)

Two patients, aged 24 and 19 years, who had undifferentiated lymphoma, developed the acute onset of focal neurologic deficits 10 days after treatment with moderate-dose methotrexate (2.76 g/m2 by 42-hour intravenous infusion) and 12.5 mg of intrathecal methotrexate. Prior chemotherapy also included intravenous cyclophosphamide, doxorubicin, vincristine, oral prednisone, and intrathecal cytosine arabinoside. Dysarthria with left hemiparesis was noted in one patient and inability to speak and quadriparesis in the other. Cerebrospinal fluid and cranial computerized tomography results were normal; however, EEGs showed focal abnormalities in both patients. Full neurologic recovery occurred within 48 hours. These symptoms developed early in the course of treatment and have not recurred in one patient who continued to receive the same regimen. The mechanism for this neurologic dysfunction is unclear. A similar picture has been reported in patients receiving high-dose methotrexate (8-10 g/m2) for osteogenic sarcoma.

Central pontine myelinolysis was found histologically in a young man who died with Hodgkin's lymphoma. Clinically he had developed a progressive peripheral sensory deficit, ataxia, quadriparesis, dysarthria, incontinence and drowsiness. This is the fifth case reported in the British literature. The pathogenesis and aetiology of this primary demyelinating disease are considered.

A patient development deteriorating mental status, quadriparesis, and severe pseudobulbar palsy with the inability to speak or swallow following orthotopic liver transplantation (OLT). Subsequently, abnormalities were found in the pons on MRI that were consistent with central pontine myelinolysis (CPM). Marked recovery occurred following transfer to the rehabilitation medicine service. Seven months following development of CPM, a mild dysarthria has persisted, but full ambulation has returned. Although no significant fluctuations in serum sodium were seen perioperatively, multiple risk factors associated with the development of CPM were present, including end-stage liver disease, a history of alcohol abuse, malnutrition, hypoxia, and use of cyclosporin medication postoperatively. This case demonstrates that the development of CPM may occur following OLT despite meticulous attention to serum sodium concentrations. We conclude that CPM is multifactorial in nature. There can be a great variation in its clinical course.

A 44-year-old man developed a clinical syndrome characterized by nonprogressive spastic quadriparesis, dysarthria, and dysphagia following a severe cervical hyperextension injury. These clinical features, coupled with normal neuroimaging studies, are consistent with a stretch injury of the corticospinal and corticobulbar tracts at the pontomedullary junction.
