A 60-year-old diabetic male presented with transient ischemic attacks. Initial neurological examination and head CT were normal. Dysarthria, ataxia, delirium, and lethargy developed. A diagnosis of cryptococcal meningitis was made after lumbar puncture and treatment with intravenous amphotericin B and 5-fluorcytosine was begun. A repeat head CT showed an anterior cerebral artery territory infarct. His condition worsened and he died of associated complications three weeks after admission. The case is used to discuss the association between cryptococcal meningitis and diabetes, transient ischemic attacks, and vasculitis with cerebral infarction.

Typical symptoms of hypothyroidism are lethargy, cold intolerance, slowing of intellectual and motor activity, declining appetite, increasing weight, and dry skin. A 43-year-old man with hypothyroidism presented with dysarthria as the leading symptom. Further symptoms were cramps in the legs after exercise, dizziness, and stunned feeling. He suffered from severe snoring for 4 years, and obstructive sleep apnea syndrome was diagnosed 2 years before. Creatine phosphokinase was elevated. Electromyography was myogenic. Echocardiography showed a thickened myocardium. An otolaryngologic investigation revealed macroglossia and hypertrophy of the uvula. After administration of L-thyroxine, the symptoms rapidly improved. Dysarthria may be the leading symptom of hypothyroidism and can be promptly resolved after hormone substitution.

A 64-year-old woman presented with sudden onset of disequilibrium and dysarthria. Two days later she became lethargic and tetraparetic. An emergency MRI disclosed multiple infarctions in the medulla oblongata and pons. An angiogram revealed severe stenosis of the rostral basilar artery. The patient underwent a rapidly progressive course with impaired consciousness and flaccid tetraplegia. MR images 7 days after the onset disclosed a symmetrical midbrain infarction that was localized mainly in the cerebral peduncles, suggesting a distal basilar artery occlusion as the cause of this pathology. Since 4 weeks after the onset the patient was in the persistent vegetative state, which was essentially unchanged during the 1-year follow-up period. Persistent vegetative state is known to be caused by diffuse supratentorial or bilateral thalamic lesions, but in our case the lesions were restricted to the infratentorial area. We speculate a mechanism to cause the persistent vegetative state by partial impairment of the connection to the thalamic ascending system or extrathalamic ascending system, which leads to the dissociation of arousal(preserved in this case) and awareness(impaired in this case) after the ventral midbrain infarction.

Central pontine myelinolysis (CPM) is a demyelinating disease of the pons often associated with the demyelination of extrapontine areas of the central nervous system. Although the etiology and pathogenesis are unclear, CPM is usually associated with hyponatremia or its rapid correction, and chronic alcoholism is also a common underlying condition. We observed a 43-year-old man with diabetes mellitus who developed central pontine and extrapontine myelinolysis with no apparent evidence of hyponatremia, serum hyperosmolality or associated rapid correction, or history of alcohol abuse. On admission, the patient was lethargic with dysarthria, dysphagia, and mild tetraparesis and his face and lower extremities were severely edematous. Laboratory examination showed normoglycemia and normonatremia, although hypokalemia, elevated HbA1c, and nephrotic syndrome were also present. Magnetic resonance imaging (MRI) revealed abnormal signal intensity in the pons, the deep layers of the cerebral cortex, and the adjacent white matter consistent with central pontine and extrapontine myelinolysis. Generalized edema was reduced by the use of diuretics and extracorporeal ultrafiltration without significant changes of serum sodium or osmolality. His consciousness level and paresis gradually improved within a few weeks. Our patient is a rare case of CPM associated with diabetes without apparent evidence of sodium or glucose imbalances.

The case of a 63-year-old woman who presented with status epilepticus, coma and hypoventilation is reported. A primary neurological cause was considered. Hypothermia led to further investigations and a diagnosis of severe hypothyroidism. The neurological complications of hyperthyriodism include alteration in mental status with slowness, decreased concentration and lethargy, headache, cranial nerve palsies, dysarthria, hoarseness, myopathy, neuropathy, reflex changes, ataxia, and psychotic episodes. Our patient suffered from a rare consequence of severe hypothyroidism presenting with status epilepticus and she died despite treatment. To our knowledge this is the second patient to be reported with myxoedema coma with this kind of presentation. Despite therapeutic options, there is a high mortality rate.

We describe an autopsy case of MM1-type sporadic Creutzfeldt-Jakob disease (CJD), the duration of which was 93 days. The patient was a 59-year-old Japanese man with no family history of prion disease or known iatrogenic exposure to CJD. His first symptom was dysesthesia in the left arm, suggestive of cervical cord involvement, and he showed rapidly progressive neurologic signs, such as dysarthria, dysphagia, lethargy, sleep apnea and respiratory failure, suggestive of brainstem involvement. Progressive mental deterioration combined with episodes of myoclonic seizure and periodic synchronous discharges on the electroencephalogram were observed in the later disease stage. Autopsy showed typical spongiform change to be wide-spread in the cerebral and cerebellar cortices, thalamus and basal ganglia. Synaptic-type PrP deposition was marked in the cerebral cortex, thalamus and basal ganglia. In the cerebellum, although the granular, molecular and Purkinje cell layers were well preserved from neuronal loss and gliosis, PrP deposition was marked in the molecular and granular cell layers. Spongiform degeneration and neuronal loss were not seen in the brainstem and spinal cord, but relatively marked PrP deposition was observed in the quadrigeminal body, substantia nigra, pontine nucleus, inferior olivary nucleus and posterior horn. Immunohistochemical staining for HLA-DR showed proliferation of activated microglia in the cerebral and cerebellar cortices, pontine nucleus, inferior olivary nucleus and posterior horn. The mechanisms underlying the neurologic symptoms and signs were unclear, but we speculate that, in addition to widespread involvement of the cerebral cortex, PrP deposition and microglial activation in the brainstem and spinal cord were responsible.

Acute movement disorder associated with reversible bilateral basal ganglia lesions is an increasingly recognized syndrome in patients with end-stage renal disease, especially in the setting of concurrent diabetes mellitus. We report an elderly man with end-stage diabetic nephropathy treated by daily automated peritoneal dialysis who developed subacute symptoms of gait disturbance, dysarthria, dysphagia and lethargy. Computed tomography and magnetic resonance imaging of the head revealed bilateral symmetrical basal ganglia lesions. Repeat imaging 3 weeks later showed that these lesions had regressed spontaneously. However, his neurological symptoms improved slowly. These findings were similar to 23 other cases in the literature. Review of these cases shows that clinical features were predominantly bradykinesia, gait disturbance and concurrent metabolic acidosis (observed in 90% of cases). The pathogenesis of this condition has not been clearly defined, but uraemia may be an aggravating factor in predisposed patients, particularly in the presence of diabetic microvascular disease. There is no specific treatment for this condition; supportive measures are the mainstay of management. In the majority of patients, neurological improvement lags behind regression of basal ganglia lesions seen with neuroimaging, and the long-term outcome is variable.

Central pontine myelinolysis and extrapontine myelinolysis are rare demyelinating diseases of the central nervous system. These diseases are related frequently to rapid correction of hyponatremia. They have also been described in association with other underlying conditions such as alcoholism and malnutrition. In the present study, we report a case of central pontine and extrapontine myelinolysis with acute hepatic dysfunction. The patient had no apparent evidence of hyponatremia and no history of alcohol abuse. On admission, the patient was lethargic; dysphagia, dysarthria, and quadriplegia were noted. Laboratory examination showed significantly increased transaminase without hyponatremia. Magnetic resonance imaging revealed abnormal signal intensities in the pons and thalamus. Consciousness level and clinical symptoms improved gradually within a week. We suggest that acute hepatic dysfunction may play an important role in the development of central pontine myelinolysis and extrapontine myelinolysis.

Burkitt lymphoma is a type of B-cell lymphoma that occurs mostly in children, and rarely in adults. The sporadic type is known to occur mostly at the ileum and cecum. Cytarabine, which is used for central nervous system prophylaxis during chemotherapy for Burkitt lymphoma, has known neurotoxicity, and its side effects include motor ataxia due to cerebellar injury, ataxic dysarthria, dysfunction of ocular movement, confusion, somnolence and lethargy. This case report is about a patient diagnosed with Burkitt lymphoma who manifested motor ataxia after chemotherapy that included cytarabine.

A 25-years-old man experienced fever and diarrhea. Ten days later he noticed difficulty walking (day 1). On admission neurological examination revealed lethargy, dysarthria and weakness of limbs. Oculocephalic response was not be elicited and extensor toe signs were positive. In spite of treatment with aciclovir and methylprednisolone, he continued to show progressive deterioration developing to coma with decorticate posture. Autonomic symptoms (hyperhidrosis, hypersalivation and fever) and groaning were observed. Brain magnetic resonance image and brainstem evoked potential presented no abnormality, but electroencephalographic study showed a spindle pattern indicating spindle coma. Laboratory tests including cerebrospinal fluids showed no specific results. High-dose immunoglobulin was administered from day 6, and his consciousness level improved. External ophthalomoplegia and ataxic gait were observed after he became more alert. Because he had IgG type anti-GQ1b antibodies in the serum, a diagnosis was made of Bickerstaff's brainstem encephalitis (BBE). Six months after discharge he had complete resolution of his symptoms. This is the first report of spindle coma observed in a case of serologically confirmed BBE.
