Thirty-four patients were submitted to the conventional cervical myelography by administration of metrizamide (Amipaque) through three routes (lumbar 23, suboccipital 6, C1-C2 lateral 5). After the injection of metrizamide (4-11 ml, 170-250 mgI/ml), all procedures of the cervical myelography were done as soon as possible within 9 minutes. The adverse reactions of Amipaque were observed in 29 cases (85%) out of 34 cases initially 1 hour after cervical myelography and disappeared completely in an average of 16 hours. The total number of the side effects was 140 incidences such as meningeal irritation (headache 18, nausea 17, vomiting 17), cerebellar signs (dizziness 11, dysarthria 8, tremor 5, bradylalia 2, dysmetria 2, tipsy feeling 2, dysdiadochokinesis 1), autonomic signs (flushing 7, pale face 4, fever 4, sweating 2, hiccup 2, fatigability 2, micturition disturbance 1), sensory signs (exacerbation of numbness 6, perioral numbness 3, back pain 1, chest pain 1), motor signs (focal muscle spasm 5, exacerbation of paresis 4, areflexia 1), psychiatric signs (dysphasia 3, disturbance of consciousness 2, euphoria 1, persecutory delusion 1) and muddiness 7. We observed that waxing and waning of side effects correlated tightly with transient cortical penetration of dye in CT and cortical dysfunction mainly slowing of the background activity and slow wave burst in EEG. According to high frequency of side effects in our study, we suggest that a greater incidence of side effects may result when high concentration of Amipaque comes in contact with the cerebral cortex by using an inadequate fluoroscopic table which has only fixed one plane image and rough positioning control. Slow absorption into blood stream may affect appearance and maintenance of side effects. In order to decrease side effects after Amipaque cervical myelography, we propose that we should introduce a mobile rotating chair coupled with high power image and chose C1-C2 lateral route using 1500-1700mgI of Amipaque.

Clinical features of cerebellar infarction in the territory of the superior cerebellar artery (SCA) were investigated in six male patients, ranging in age from 50 to 69 years. In all patients, there were MR images of infarction located in the area supplied by the SCA. The lesion was on the left-side in 2, right-side in 3 and bilateral (recurrent) in 1 patient. The onset of disease occurred with nausea, vomiting and floating sensation, with no overt brain stem signs other than symptoms of unilateral cerebellar ataxia and dysarthria. Five of the 6 patients had heart disease and cerebral angiography without definite evidence of SCA occlusion, strongly suggesting occlusion of the artery at its periphery due to cardiogenic embolism. A comparison of these 6 patients with those reported previously in Japan suggests that patients with SCA occlusion may be divided into two distinct subgroups: one manifesting diffuse brain stem signs in addition to cerebellar signs, and the other showing cerebellar signs as the only neurologic manifestation. In the former group, comprising the vast majority of patients, SCA occlusion occurred at the origin of the vessel due to a thrombus under a state of hypertension, diabetes mellitus or malignancy, producing signs of brain stem involvement, such as dissociating sensory disturbance and Horner's sign. While in the latter group, which included these 6 patients, paucity of brain stem signs, absence of definite cerebral angiographic evidence of SCA occlusion, and the presence of heart disease were distinguishing clinical features. Cardiogenic cerebral embolism was probably the underlying pathology in many of the cases and the functional prognosis was favorable.

This is a report of unruptured aneurysms with occlusion of the basilar artery. A 61-year-old female was admitted to our hospital because of dysarthria and numbness of her left face. Angiography revealed occlusion of the basilar artery and severe arteriosclerosis of the bilateral cerebral carotid arteries. Pcom was not visualized on bilateral carotid angiogram. These neurological signs were considered to be derived from vertebrobasilar insufficiency by occlusion of the basilar artery. Right STA-SCA anatomosis was performed to prevent brain stem infarction. Postoperative angiography showed a good filling of both PCA and SCA by collateral circulation via a right STA and an unruptured basilar top aneurysm. Seven months after the bypass surgery, angiography disclosed that the basilar top aneurysm was visualized clearly, and its size was unchanged. The fact that there was no thrombus formation in the aneurysm was considered to be due to ticlopidine, and the hemodynamic changes after the bypass surgery were suspected to have increased the intraaneurysmal pressure. Therefore we performed neck clipping of the basilar top aneurysm by using a right pterional approach. Two years after the second operation, the patient complained of severe headache and vomiting. CT scan showed subarachnoid hemorrhage, and angiography demonstrated a newly developed aneurysm which might have ruptured on left internal carotid anterior choroidal artery bifurcation. Emergency neck clipping of the second aneurysm was performed, and the patient showed a good postoperative course. The newly developed second aneurysm might have been caused by severe arteriosclerosis and hypertension in addition to hemodynamic stress.

This study included 125 cases of cerebellar infarction followed during an average period of 4.3 years. The diagnosis was made by CT or MRI. Infarctions localized to the territory of the superior cerebellar artery (SCA) and the territory of the posterior inferior cerebellar artery (PICA) occurred with the same frequency. Transient ischemic attacks preceded infarction in 26% of cases. Symptoms and signs were usual with sudden association of headache, dizziness, unsteadiness and vomiting. Vestibular signs were more important in infarctions of the PICA territory; cerebellar signs and dysarthria were more frequent in infarction of the SCA territory. A decreased level of consciousness developed in only 21% of cases. Surgical operation was required in 9 cases. Investigations have showed the large responsibility of cardiac embolisms and atherosclerosis. Short term outcome was more often favourable: 116 patients were alive at the end of the first month; 80% of survivors were independent one year later. At 5 years, 73% of patients were alive. After the acute period, mortality was mainly due to cerebro-vascular and cardiac events.

We report a 78-year old woman with 30 years history of rheumatoid arthritis and nephrotic syndrome, who developed right hemiparesis and renal failure recently. The patient was diagnosed as having rheumatoid arthritis in 1965, and had been treated with gold -sol, steroid hormone, and non-steroidal anti-inflammatory drugs intermittently. Later on her clinical course was complicated by nephrotic syndrome, however, her renal function was well compensated. Otherwise, she was apparently doing well until October of 1988 when she had an onset of anomic aphasia; she was 73-year-old at that time. She was admitted to our hospital; a cranial CT scan at that time revealed a low density area in the left temporal region, and she was diagnosed as suffered from an atherothrombotic infarction involving the left middle cerebral artery territory. She recovered soon and was discharged for out patient follow up with ticlopidine 100 mg/day. She was doing well until December 15, 1990, when she had an acute onset of nausea, vomiting, and speech disturbance; she was admitted to our hospital for the second time. On admission, she was alert, but she had motor aphasia, right hemiparesis, and dysarthria. A cranial CT scan revealed a low density area in the left temporal region extending into adjacent frontal and parietal areas including the angular gyrus; in addition, leukoaraiosis, cortical atrophy, and ventricular dilatation were noted (Fig. 1A, B). She was treated supportively, and she showed improvement in her aphasia, however, moderate weakness remained in her right upper and lower extremities. She was discharged for out patient follow up. She was doing well until May 21, 1993, when she developed difficulty in swallowing and speech. She became unable to take foods orally and she was admitted again on May 31. On admission, she was afebrile and BP was 120/80 mmHg. General physical examination was unremarkable except for pitting edema and multiple contracture of her joints. On neurologic examination, she was alert but appeared to have aphasia and dementia; she could utter only a few simple words, and was able to understand only simple questions.(ABSTRACT TRUNCATED AT 400 WORDS)

A 25-year-old woman suffered from hyperemesis gravidarum when she was seven weeks pregnant. Since her vomiting continued, she received intravenous dextrose and electrolytes without thiamine in a hospital. One month later, she developed gait disturbance, followed by confusion and dysarthria. On admission to our department, she was confusional and had ataxic dysarthria. Spontaneous and gaze evoked nystagmus was present. Limb coordination was bilaterally ataxic. Based on her clinical course and symptoms, she was diagnosed as having Wernicke's encephalopathy. From the admission day, intravenous infusion of vitamin B1 (600 mg/day) was started. A few days later, her consciousness and limb ataxia began to improve. However, truncal ataxia and polyneuropathy became evident. Eight weeks after onset, she developed Korsakoff's psychosis such as anterograde and retrograde amnesia, disorientation and confabulation. We administered large amounts of corticosteroid (methylprednisolone 500 mg/day) in order to reduce brain edema or stabilize the impaired blood-brain barrier. Soon after, her psychosis began to improve gradually. She recovered remarkably from the psychosis, but she was left with persistent nystagmus, mild ataxic gait and polyneuropathy. The present case suggests that corticosteroid may have the beneficial effect on Wernicke-Korsakoff syndrome.

Cerebellar infarcts have been neglected for a long time and are now shown well by CT and especially MRI. Some infarcts involve the full territory supplied by a cerebellar artery. They are frequently complicated by edema with brain stem compression and supratentorial hydrocephalus, requiring at times emergency surgery, and are often accompanied by other medullary, medial pontine, mesencephalic, thalamic and occipital infarcts. On the other hand, partial territory infarcts are usually confined to the cerebellum and have a benign outcome with total recovery or minimal disability. They are more common than full territory infarcts. However, clinical presentations are similar to those full territory infarcts, differing mainly by the lack of drowsiness or unconsciousness. The main symptoms are vertigo, headache, vomiting, unsteadiness of gait and dysarthria. Signs include ipsilateral limb dysmetria, ipsilateral axial lateropulsion, ataxia and dysarthria. Vertigo is more severe and rotary in posterior inferior cerebellar artery territory infarcts, whereas dysarthria and ataxia are prominent in superior cerebellar artery territory infarcts. A few brain stem signs are sometimes added. In these territorial cerebellar infarcts, cardioembolism is the most common cause. Atherosclerotic occlusion comes next, involving the intracranial part of the vertebral artery and, less frequently, the lower basilar artery, both locations inaccessible to surgery. Other causes are artery to artery embolism from a vertebral artery origin stenosis, or the aortic arch, in situ intracranial branch atherosclerotic occlusion, and vertebral artery dissection. Border zone cerebellar infarcts occur in one third of the cases. They are small cortical or deep infarcts. They have the same symptoms and signs as territorial infarcts except for more frequent postural symptoms occurring over days, weeks or months after the ischemic event. The infarcts mainly have a thromboembolic mechanism, and sometimes have a hemodynamic mechanism: 1) focal cerebellar hypoperfusion due to large artery occlusive disease in more than half the cases, 2) small or end (pial) artery disease due to hypercoagulable state (thrombocythemia, polycythemia, hypereosinophilia, disseminated intravascular coagulation), arteritis or intracranial atheroma, and 3) rarely systemic hypotension due to cardiac arrest.

The frequency of cerebellar infarctions over two and a half years was 2.7% of the 1300 hospitalized patients over that period. Sixteen patients with cerebellar infarctions were studied by using clinical manifestations and magnetic resonance imaging (MRI). Ages ranged from 41-87 (mean 63.5) years; 13 were men and 3, women. Risk factors included: hypertension (50%), diabetes (44%), prior stroke (44%), cardiac disease (38%), and hyperlipidemia (19%). Common symptoms and signs were dizziness/vertigo (75%), unsteadiness (69%), dysarthria (69%), and nausea/vomiting (50%). Infarcts mainly involved the posterior inferior cerebellar artery (PICA) territory and tended to be associated with brainstem infarcts in 14 of the 16 patients. Most cerebellar infarctions had a benign course, especially the small ones. No mortality was noted in this series. The short-term outcome of the cerebellar infarctions seemed to depend on the size of the infarcts and the sites of the artery occlusion. It was concluded that diagnosis of cerebellar infarctions requires a high index of clinical suspicion, especially when patients present with a sudden onset of ataxia, dizziness/vertigo, nausea/vomiting and dysarthria; and that MRI is a useful tool for the detailed study of cerebellar infarctions and can elucidate associated brainstem infarcts.

We report the case of a 34-year-old man, treated by chiropractic manipulation for tension-type headache. The patient complained of a sharp occipital pain during the first session, followed by vomiting and loss of consciousness, and remained comatose for five days. Neurological examination detected persistence of dysarthria, ataxia, with delayed responses. Neuroradiological findings reveal an ischemic lesion in left PICA region, confirmed by angiography. Clinical and radiological findings suggested complete remission about two months later.

Listeria monocytogenes rhombencephalitis has never been studied in a significant group of patients. We describe 14 adult cases who were seen over a 10-year period. A biphasic illness was characteristic: (1) prodromes (5-15 days) with malaise, fatigue, headache, nausea or vomiting, and fever; (2) cranial nerve palsy with facial palsy, diplopia, dysphagia, dysarthria, usually multiple. Meningism and hemi- or tetraparesis were present in 11 patients and cerebellar dysfunction in 9 patients. In 4 cases, CT showed widening of the brain stem with disappearance of the surrounding cisterns. The cerebrospinal fluid was abnormal in all patients in whom this investigation was done (pleocytosis, elevation in protein content). The patients received antibiotic therapy for 2-6 weeks. In the 9 patients who recovered, the neurological dysfunction improved within 2 days to 1 week of the initiation of therapy. There were 5 deaths. At autopsy in 2 cases, there was severe purulent meningitis and rhombencephalitis with predominantly polymorphonuclear cellular infiltration in 1 case, while numerous microabscesses in the midbrain, pons and medulla were observed in the other. We conclude that L. monocytogenes infection should be considered in patients who develop fever and focal neurological signs particularly localized to the brain stem.
