Antecubital venous blood was sampled from stroke patients in the presence of disodium ethylenediamine tetraacetate. Plasma was analyzed for cyclic AMP applying a competitive protein binding method without any special pretreatment. In mild hemispheric infarction as manifested by moderate hemiparesis and/or dysarthria, plasma cyclic AMP remained in the normal range (8-18 picomoles/ml). In most of the cases with moderate infarction, the cyclic AMP level was distinctly below the normal range several days after the onset of symptoms. However, cyclic AMP remained in the normal range in severe infarction with signs of brain edema, and in two cases with moderately severe symptoms. One of the two cases suffered from later development of brain edema, and the other revealed a large lesion in brain scintigrams. The sizes of the lesion revealed in brain scintigrams were smaller in the moderate cases and larger in the severe cases, except in one of the cases mentioned above. It appeared that with plasma cyclic AMP levels we could predict the extent of the lesion, and perhaps the subsequent development of impending brain edema in a few days after the onset of cerebral infarction. In moderate cases of cerebral hemorrhage, judged from the consciousness, cyclic AMP decreased to a subnormal level 2-4 days after the onset. In severe cases it remained in the normal range. Subarachnoid hemorrhage showed significantly elevated cyclic AMP levels in the early stage.

The patient, a 37-year-old female, was hospitalized with a severe headache. Neurological examination on admission revealed no deficits except for neck stiffness and somnolence. Computed tomography showed a subarachnoid hemorrhage, which was especially prominent in the supracerebellar and quadrigeminal cisterns, but demonstrated no ventriculomegaly. Cerebral angiography on admission revealed no apparent abnormalities, but repeat angiography 8 days later disclosed a saccular aneurysm (2 X 3 mm) arising from the hemispheric branch of the left superior cerebellar artery (SCA). Three days after admission, the patient developed cerebellar dysarthria, which was assumed to be due to vasospasm. On the 24th day after admission, the aneurysm was successfully clipped through the infratentorial-supracerebellar approach. The postoperative course was uneventful and the patient was discharged with no neurological deficit. Nineteen other cases of peripheral SCA aneurysm have been reported in the literature. The presence of this type of aneurysm should be considered in patients who are fairly young and have focal neurological signs, such as third or fourth nerve palsy and/or cerebellar dysfunction. The prognosis for such patients is good, except in cases in which the neurological status is poor at the onset.

Linear fractures through the occipital bone are common, whereas depressed fractures in the posterior cranial fossa are rare because the occipital bone is protected by the surrounding thick muscles. The authors describe an unusual case of depressed fracture localized in the posterior cranial fossa associated with the syndrome of acute central cervical spinal cord injury. A 50-year-old female struck her face against the table and fell backward, while drunk, resulting in the bruise over the occipital region. Three days after injury she was transferred to our hospital because of progressive disturbance of consciousness, brain stem dysfunction and tetraplegia. Neurological examination on admission showed that she was drowsy, had tetraplegia and could not speak. However, she could obey commands only by moving her eyes and the ocular movements were normal in all directions except for horizontal nystagmus. Plain skull x-ray revealed a conspicuously depressed fracture in the posterior cranial fossa, but cervical spine x-ray showed neither fracture nor dislocation. Immediately suboccipital craniectomy was done and there were a thin subdural hematoma on the cerebellar surface, cerebellar contusion, and subarachnoid hemorrhage around the cisterna magna. Soon after operation impaired consciousness and paraplegia were improved, but recovery of both arms was delayed. Five months after injury, she still had left IX, X and XI nerve paresis, bilateral arm weakness, dysarthria, swallowing disturbance and bilateral sensory disturbance below C4 level. These findings indicated that she had sustained brain stem and cerebellar compression by the depressed fracture and also had suffered an acute central cervical spinal cord injury.

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.

Superficial hemosiderosis (SH) of the CNS is a rare disease caused by repeated subarachnoid hemorrhage, with progressive superficial siderosis of the CNS. We report a patient with SH whose clinical picture was marked by progressive gait ataxia, hearing loss, dysarthria, and recurrent episodes of hemifacial spasm. Iron and ferritin levels in the CSF were significantly higher than in a control group of patients. Six month's treatment with the iron-chelating agent trientine dihydrochloride led to clinical improvement, with a concomitant reduction of CSF iron level. We suggest that, in addition to magnetic resonance imaging findings, CSF levels of iron and ferritin should be used as diagnostic criteria for SH, as well as to estimate the efficacy of iron chelation treatment.

Two cases of cerebral vasculitis of the central nervous system are reported. In our cases, systemic investigation found no underlying cause for vasculitis. Case 1: A 59-year-old female presented severe headache due to subarachnoid hemorrhage. CT scan obtained one month later demonstrated a low density area with ring-like enhancement in the right frontal lobe. A surgical specimen revealed inflammation of the leptomenigeal vessels with many lymphocytes. Case 2: A 64-year-old female came to us with dysarthria and slight left hemiparesis. CT scan and MRI obtained after admission demonstrated an abnormal mass lesion with enhancement in the right frontal lobe. The histological examination revealed vasculitis. After systemic disease and central nervous system infection were excluded, we diagnosed this case as cerebral vasculitis of unknown origin. In this paper, the clinical and pathological features of cerebral vasculitis and differential diagnosis were discussed.

A 28-year-old woman was hospitalized with dysarthria and oro-mandibular and upper limb dystonia. Approximately 8 years prior to the current admission, the woman became severely hyponatremic due to traumatic subarachnoid hemorrhage-related SIADH. Brain MRIs showed a signal increase in the central pons, thalamus and striatum on T2 weighted images compatible with central pontine and extrapontine myelinolysis. From a few months after that event, dystonia progressed slowly over the subsequent 8 years. We speculate that the particular damage chiefly to the myelin structures by myelinolytic process may have caused an extremely slow plastic reorganization of the neural structures, giving rise to progressive dystonia.

A 71-year-old female was admitted with the complaints of dysarthria and right hemiparesis. CT scan revealed subarachnoid hemorrhage in the left cerebral sulcus. The first angiography was performed 3 days after the onset and left carotid angiography revealed a small aneurysm arising from the left middle cerebral artery. After 3 weeks of antibiotic therapy, the second angiography showed the aneurysm to be clearly enlarged, so it was resected. The patient complained of marked dysarthria a day after the operation and CT scan revealed a new infarction in the right frontal lobe. The third angiography showed an aneurysm arising from the right middle cerebral artery and the fact that two peripheral arteries of the aneurysm had disappeared 3 weeks after the first operation. The second operation was performed and a bacterial aneurysm was resected. The patient left the hospital without any neurological deficits. Septic embolism is the most important complication of infective endocarditis and it is usually presented with subarachnoid hemorrhage and intracerebral hemorrhage caused by ruptured bacterial aneurysms. In this case the septic embolism occurred two times. At each time cerebral ischemic attacks were presented. The reason why this case presented with ischemic symptoms was suspected to be that embolisms occurred at the trifurcation of the distal middle cerebral arteries. We were able to detect a bacterial aneurysm angiographically 3 days after the ischemic attack and we suspected that a bacterial aneurysm had been able to develop within 3 days after the septic embolism.

Because of its large spectrum of clinical manifestations, diagnosis of cerebral venous thrombosis may be very difficult. Since appropriate treatment influences prognosis, early recognition of this condition is extremely important. We report a subarachnoid hemorrhage as a rare initial manifestation of cerebral venous thrombosis. A 58-year-old woman was admitted with severe headache of sudden onset, neck stiffness, dysarthria, and ataxia. Computed tomography scan showed a subarachnoid hemorrhage in the right posterior fossa. Magnetic resonance imaging coupled with magnetic resonance angiography revealed right transverse/sigmoid sinus thrombosis with hemorrhagic infarction of the right cerebellar hemisphere leading to a pseudotumoral appearance and displacing the fourth ventricle. Anticoagulant treatment resulted in rapid clinical recovery and in resolution of the radiological signs of infarction and of the subarachnoid and subdural hemorrhages.

A 58-year-old male presented with a dissecting aneurysm of the basilar artery manifesting as dysarthria, left hemiparesis, and numbness of the left side. Angiography revealed a double lumen at the midportion of the basilar artery which was consistent with a diagnosis of dissecting basilar artery aneurysm. The patient was treated conservatively, and remained neurologically stable for a 5-year period following initial presentation, but serial magnetic resonance imaging revealed growth of the aneurysm compressing the brain stem. His condition then worsened. Computed tomography revealed obstructive hydrocephalus. Ventriculoperitoneal shunting was performed and the patient's symptoms improved. However, he died of subarachnoid hemorrhage. Autopsy showed the patient had had a type 3 "dolichoectatic dissecting aneurysm." Surgical treatment should be seriously considered for treating the patients with dissecting basilar artery aneurysm causing brain stem ischemia, especially if the aneurysm is growing. High-flow bypass and proximal occlusion may be the choice in patients with poor collateral circulations.
