Cerebrotendinous Xanthomatosis (CTX) is a rare familial disease characterized by tendon-xanthomas, cataracts, progressive cerebellar ataxia, dementia and an elevation of serum cholestanol with normal levels of cholesterol. Although the pathogenesis of CTX is not fully understood, increment of cholestanol is suggested one of the major metabolic derangements of the disease. Recently, the LDL-apheresis has been developed as a new therapeutical equipment in the field of hyperlipidemia and been widely used to reduce the levels of LDL-cholesterol by selective LDL adsorption. From the point of view that cholestanol is involved mainly in LDL-cholesterol (1.019 less than d less than 1.063), we used this LDL-apheresis in the aim of reducing the cholestanol in 58 years old woman with typical sign and symptoms of CTX. The levels of serum cholestanol and cholesterol before the treatment with LDL-apheresis, were 10.7 micrograms/ml and 175 mg/dl respectively. Also the ratio of cholestanol/cholesterol indicated 0.63. By the first procedure of apheresis, the level of cholestanol was markedly decreased to 5.2 micrograms/ml (50%). Several LDL-apheresis treatments were carried out once a month. During 5 months treatments, neurological deterioration was arrested, dementia which included disorientation and recent-memory loss, cleaned a little. Although the xanthomas did not decrease in size, this patients was better oriented to person, place, time and was able to speak rationally, 2nd her cerebellar dysfunction revealed improvement. From our new experiments-we believe that the LDL-apheresis offers the strong hope of preventing the progress on cerebrotendinous xanthomatosis.

Sixteen patients with infarction in the region supplied by the anterior inferior cerebellar artery (AICA) were studied to assess the mechanism and its clinical features. Risk factors involved hypertension, diabetes mellitus, a history of cerebrovascular disease and hyperlipidemia in seven patients (44%), while smoking was found in six (38%). The pathogenesis of these patients was thought to be thrombotic in all 16 patients, and lesions of the vertebrobasilar system were noted in 7 out of 13 patients (54%) who underwent cerebral angiography. Gasperini syndrome (AICA syndrome+abducens paralysis) occurred in two patients (13%), and five patients (31%) showed only cerebellar ataxia (3 had infarction confined to the middle cerebellar penduncle and 2 had infarction confined to the cerebellar hemisphere). As a result of analysis of clinical symptoms in nine patients with the incomplete AICA syndrome, loss of hearing in six patients (67%) and cerebellar ataxia in all nine patients were noted. We postulated that large-artery occlusive disease or branch atheromatous disease resulted in an infarction in the region of the AICA. It is necessary to consider infarction of the AICA region in patients who present a unilateral hearing loss and cerebellar ataxia.

Clinical features of the anterior inferior cerebellar artery (AICA) territory infarcts were investigated in ten patients, ranging in age from 38 to 76 years. In all patients, there were MR images of infarction located in the area supplied by the AICA. The lesion was on the left side in 6 patients and right side in 4. The lesion of brain stem including the middle cerebellar peduncle was found in 7 patients and that extended to the cerebellum was in 3 patients. The main ipsilateral neurological signs were the VII and VIII cranial nerves palsy and cerebellar ataxia. The V and VI cranial nerves palsy. Horner's syndrome, and dysphagia were also present. The main contralateral sign was superficial sensory disturbance, but no hemiplegia. The underlying pathology included chiefly hyperlipidemia, hypertension, and diabetes mellitus. Cerebral angiography was performed in 8 patients, most of which was observed severe arteriosclerosis suggesting poor hemodynamics in the vertebral and basilar arteries. The prognosis was relatively good, but the VII, VIII, and V cranial nerves palsy and contralateral superficial sensory disturbance remained as the sequelae. As mentioned above, there were various neurological findings and MR images in AICA territory infarcts. Especially there were some patients whose lesion extended to the upper medulla and neurological findings were similar to the Wallenberg syndrome. It is important that one investigates not only axial slices but also coronal slices of MR image to estimate the extension of AICA territory infarct.

We report clinicopathological features of a Japanese family with hereditary motor and sensory neuropathy associated with cerebellar atrophy (HMSNCA). Four affected members from a single generation were examined. They shared common clinical features, including insidious onset in teenage, slowly progressive cerebellar ataxia, amyotrophy, sensory disturbance, and dementia. In addition, all the patients showed hypoalbuminemia and hyperlipidemia and a marked atrophy of the cerebellum on magnetic resonance images. Autopsy of the proband revealed a severe loss of Purkinje cells, degeneration of posterior columns and spinocerebellar tracts of the spinal cord, and a marked loss of myelinated and unmyelinated fibers in the peripheral nerves. We consider that HMSNCA is a distinct form of hereditary multisystem neuronal degeneration.

We report a 58-year-old man with slowly progressive muscle atrophy and weakness in the four extremities, accompanying cerebellar ataxia and sensory impairment of all modalities. He was a product of consanguineous marriage. His neurological manifestations began in childhood. He was admitted to our hospital because of marked abdominal distension and pretibial edema with hypoalbuminemia and hyperlipidemia. Neuroimaging studies showed marked atrophy of the cerebellum and spinal cord. Nerve conduction studies presented with slowing and sural nerve biopsy revealed demyelination with onion-bulbs. Abdominal distension was interpreted to be caused by chronic idiopathic intestinal pseudo-obstruction (CIIP), leading to protein-losing gastroenteropathy and hypalbuminemia caused by the CIIP. He died of DIC by myelodysplasic syndrome and DIC, two years later. Postmortem study demonstrated with severe loss of anterior horn cells and gliosis in the spinal cord. The Clarke's column was also affected. There was symmetrical degeneration in the dorsal column and corticospinal tracts. The cerebellum showed atrophy of molecular layer, prominent loss of Purkinje's cells and sparse granular cell layer, but no obvious change in the dentate nucleus. Neuronal loss in the dorsal root ganglia was remarkable. There were no alternations in the cerebral cortex, striatum, thalamus, subthalamic nucleus, and pontine nucleus, except for mild changes in substantia nigra and inferior olivary nucleus. This case was clinically suspected either of variant of Friedreich's ataxia or an early onset ataxia associated with hypoalbuminemia (EOAHA), although marked autonomic dysfunction was atypical. But the postmortem study, demonstrated with marked neuronal loss in anterior horn cells and cerebellan cortex and rather suggested an independent category of this case.

We experienced a case of 62-year-old woman who was admitted for the evaluation of her trembling hands. She was diagnosed as Williams syndrome (WS) by fluorescent in situ hybridization (FISH) analysis. She was short in stature, had a characteristic face and moderate mental retardation, whereas she was talkative and gregarious. She also presented impaired visuospatial cognition, cerebellar ataxia and tremor like involuntary movement of the hands. No remarkable abnormality is noted in MRI of the brain. MRA study of the brain revealed the arteriosclerotic vascular change, such as elongation of basilar artery and dilatation of bilateral carotid arteries. Heterozygous microdeletion of chromosome 7q11.23 of this patient is typical for WS, the delction including elastin (ELN) and LIMK 1 gene. Although she was complicated by diabetes mellitus and hyperlipidemia, she had no cardiovascular abnormalities like supravalvular aortic stenosis (SVAS), and survived to her age in good condition. The tremor-like involuntary movement disappeared after her discharge and its mechanism remains to be elucidated.
