A 40-year-old hypertensive black female, who suddenly developed aphasia, lethargy, and a right hemiparesis, and a 42-year-old non-hypertensive black male, who suddenly developed intractable headache, drowsiness, and vomiting, were found by angiography to have moyamoya disease. This condition is characterized by a decreased caliber of the internal carotid arteries and bilateral occlusion of the anterior and middle cerebral arteries with visualization of an extensive collateral network of tortuous blood vessels of the rete mirabile type at the base of the brain.

38 cases of Takayasu's arteritis were reported. The mean age of onset was 23.3 years with a female: male ratio of 1:1.7. The median delay between first symptom and time of diagnosis was 12.2 years. Headache was the most common symptom of neurologic manifestations (55%). Major neurologic events occurred in 52.7% patients in this group, including TIA, cerebral infarction, hypertensive encephalopathy, lacunar infarct, seizure, paraplegia, watershed infarct, cerebral hemorrhage, Moyamoya phenomenon, and confusion in the order of frequency. A variety of mechanisms that must be taken into account in explaining this neurologic events were proposed. The secondary hypertension and cardiac complications play an important role in causing neurologic symptoms. The formation of anastomotic networks has "Jekyll and Hyde" effect on brain both in preventing or limiting the ischemic injury and in producing some special symptoms and signs, that further widen the clinical spectrum of brain involvement.

A 17-year-old boy with known moyamoya disease developed an acute subdural hematoma after a mild head trauma. He had been confined to a wheelchair with contracture in the upper and lower extremities due to juvenile rheumatoid arthritis since age 1 year. He had undergone encephalo-duro-arterio-synangiosis (EDAS) on the right and encephalo-myo-synangiosis (EMS) on the left at 13 years of age. He was admitted with headache, nausea, and vomiting after a fall from his wheelchair at age 17. Computed tomography on admission showed a large acute subdural hematoma in the right fronto-temporal region but no bleeding at the EDAS or EMS sites. Cerebral angiography 12 weeks after the head trauma revealed a remarkable reduction in the spontaneous transdural external-internal carotid anastomoses in the right frontal region. The acute subdural hematoma was probably caused by rupture of the spontaneous transdural anastomoses.

This 42-year-old man experienced a sudden onset of occipital headache. Neurological examination revealed a moderately disturbed consciousness and a moderate left hemiparesis. CT scan disclosed a hugh hematoma in the right temporo parietal lobe without intraventricular hemorrhage. A cerebral angiography demonstrated typical findings of moyamoya disease and a small saccular aneurysm at the peripheral portion of the right anterior choroidal artery, which was dilated at the collateral circulation to the parietal lobe. The hematoma was removed at once by a craniotomy. He became alert but mild hemiparesis persisted. MRI disclosed a small signal-void lesion lateral to the trigone of the right lateral ventricle. The angiography repeated three weeks after the removal of the hematoma showed the unchanged size of the aneurysm. Direct surgery for the aneurysm was performed via the right parietal transcortical approach. The aneurysm was reached under the guidance of the intraoperative angiography. Trapping of the parent artery and the excision of the aneurysm were performed. On the basis of the presence of an internal elastic lamina at the neck of the aneurysm, the surgical specimen was histologically verified to be a true aneurysm. Since the collateral circulation was well preserved during surgery, no worsening of the neurological manifestation was observed. In view of the unfavorable prognosis for a moyamoya patient with this type of the aneurysm, which often results in a massive ventricular or intracerebral hemorrhage, surgery directed to the aneurysm itself should be considered.

A case of spontaneous middle cerebral artery occlusion with moyamoya-like vessels associated with contralateral middle cerebral artery aneurysm is reported. A 23-year-old male was admitted to our hospital with complaints of severe headache and vomiting. On admission CT scan demonstrated subarachnoid hemorrhage with high density in the left Sylvian fissure and suggested a ruptured left middle cerebral artery aneurysm. Carotid angiograms demonstrated a left middle cerebral artery aneurysm and an occlusion of the right middle cerebral artery at its origin with moyamoya-like vessels. There was no occlusion or stenosis in the bilateral intracranial internal carotid arteries. Furthermore, bilateral vertebral angiograms were also normal. The aneurysm was successfully clipped. The postoperative course was uneventful and the patient was discharged with no neurological deficit. So far as we could ascertain, there have been only 21 cases reported previously of spontaneous middle cerebral artery stenosis or occlusion with moyamoya-like vessels. According to angiographic studies and transcranial Doppler ultrasound findings, we are more inclined to believe that hemodynamic changes secondary to arterial occlusion lead to the formation and growth of aneurysms of the contralateral middle cerebral artery.

A 29-year-old, 39-week-pregnant female who had headache and nausea was admitted to our hospital. She bore a baby son by natural delivery after several hours. After labor, her headache was continuous. Brain CT scan demonstrated intracerebral and intraventricular hemorrhage. After conservative treatment for two weeks, her only neurological deficiency was visual field defect. Angiography demonstrated that her left internal carotid artery had partial stenosis at the C2 portion. Her right internal carotid artery had stenosis at the C2 portion. Her right middle cerebral artery was occluded at the M1 portion, and abnormal vascular networks had developed in the ganglionic region. Stenosis was also found in the basilar artery. We diagnosed her as being a case of adult-onset, unilateral, atypical Moyamoya disease with basilar artery stenosis. As our case was of adult-onset, and as she showed no ischemic signs, we did not think that reconstructive surgery was indicated. About the posterior circulation of Moyamoya or atypical Moyamoya disease, it was reported that in cases of juvenile onset the vertebral, basilar or posterior cerebral artery was sometimes stenosed or occluded, but, in adult-onset cases, stenosis or occlusion of the posterior cerebral artery would be an abnormality. Our case is a very rare example of unilateral atypical Moyamoya disease of adult onset with basilar artery stenosis.

5 cases of ischemic strokes in young women who used oral contraceptives and smoked cigarettes are described in clinical and angiographic detail, the risk factors for moyamoya disease are discussed in a review or strokes in pill users, and the notion that oral contraceptive and smoking may cause a moyamoya pattern of stroke is proposed. The women were aged 20-32, used the pill from 2 weeks-8 years, had smoked approximately 10-20 pack-years. 2 women had headaches and 4 had transient ischemic attacks before their multifocal symptoms in visual, somatosensory and motor function, language, speech and cognition. 2 had seizures. Angiographic patterns of either supraclinoid stenosis (4) or proximal carotid artery stenosis (1) with the collateral circulation characteristic of moyamoya disease were evident in all, but there was no evidence of hemorrhagic infarction. There were no signs of atherosclerosis. Subtle signs of an immunologic process included antinuclear antibody titer of 1:160 in 1 woman, elevated sedimentation rate and elevated circulating immune complexes in another patient, and elevated cerebrospinal protein and IgG in a third woman. 4 of the patients remained stable after stopping oral contraceptives and stopping or reducing smoking. The 5th, who continued smoking, had progressive symptoms for 10 years. It was suggested that antibodies to ethinyl estradiol, a possible cause of this disorder, be further investigated.

One familial case of "moyamoya" disease affecting three patients is reported. The patient in Case 1 was a 28-year-old female. She had suffered from motor weakness of the right limbs in her infantile period. She visited our hospital because of sudden headache and left motor weakness associated with nausea and vomiting. On admission, CT scan revealed cerebral hemorrhage in the right caudate nucleus with intraventricular clots and infarction in the left parietal lobe. Angiography showed stenosis of the left ICA terminal portion and occlusion of the right side, with moyamoya vessels in the basal area. The patient in Case 2 was a 54-year-old female, who was the mother of Case 1. After an operation for acute upper intestinal bleeding, she suffered from cerebral infarction. CT scan revealed large low density areas in the territory of the bilateral MCA. Angiography showed stenosis of the bilateral ICA terminal portions, occlusion of the right MCA, stenosis of the left MCA, and moyamoya vessels in the basal area. The patient in Case 3 was a 40-year-old female, who was a younger sister of Case 2. She had a convulsive attack in her infantile period. She visited our hospital because of gradually worsening headache. CT scan revealed multiple infarctions in the left paraventricle, the right parieto-occipital and occipital lobe. Angiography showed occlusion of the bilateral ICA terminals with moyamoya vessels in the basal and the ethmoidal areas. The patient in Case 2 died immediately. Surgery for reconstruction of hemodynamics was performed in Case 1 and 3.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied five patients with cerebral hemorrhage limited to the head of the caudate nucleus. This rare localization represents 11% of central nuclei hemorrhages. This entity has various clinical expressions; some are similar to a subarachnoid hemorrhage, others show the same manifestations associated with hemiparesis and neuropsychological findings, while still in others, the neuropsychological syndrome with speech, behaviour or memory disturbances predominates. Recovery depends on the patient's previous clinical status and on the presence of associated lesions at the time of hemorrhage. Typical warning signs, like headache, are often absent in the elderly and debilitated. Meningismus is explained by the intraventricular extension of the hemorrhage. Motor deficit, usually moderate, is probably due to impairment of the anterior portion of the posterior arm of the internal capsule. Destruction of the head of the left caudate nucleus, which is part of the circuit causing "subcortical aphasias", is responsible for non specific speech disturbances, that are however remarkably rich in semantic paraphasias. These dysfunctions could be caused by a "cortical diaschisis" as suggested by SPECT analysis. Memory dysfunction as a result of caudate lesion is questioned. However confusion and behavioural disturbances, like preservations, transitory mutism and self neglect, seem characteristic. As shown by cerebral blood flow (CBF) studies, these disturbances might represent a frontal dysfunction caused by the interruption of the dorso-latero-prefrontal and orbito-frontal circuits. When the hemorrhage extends beyond the head of the caudate nucleus, behavioural changes occur due to the involvement of neighbouring structures such as the thalamus, internal capsule, temporal lobe and nucleus accumbens. Caudate hemorrhages occur mostly in the elderly, often with long-standing arterial hypertension causing lesions of the lenticulo-striate arteries. Severe stenosis or complete occlusion of the middle cerebral artery with a fragile anastomotic circuit or angiopathies in younger individuals (particularly Asiatics: moyamoya disease) are less frequent, but they should be considered and investigated by arteriography. Vascular malformations are a rare cause and a relationship with amyloid angiopathy can only be suspected.

A case of adult Moyamoya disease, with formation of a transcranial external carotid-internal carotid (EC-IC) anastomosis through burr holes which had been made previously. A 43-year-old male suffered sudden headache and vomiting. Neurological examination revealed mild consciousness disturbance and dysarthria. The computed tomography (CT) scans showed intraventricular hemorrhage, which was drained through burr holes bifrontally. The diagnosis of Moyamoya disease was subsequently made by cerebral angiography. A month later he was discharged with mild gait disturbance and mental retardation. Seven years later he suddenly complained of gait disturbance, dysarthria and sensory disturbance involving the right upper extremity. A CT scan revealed a small hemorrhage in the left putamen. Carotid angiograms disclosed transcranial EC-IC anastomosis through the burr holes which had been made previously. It is suggested that revascularization can be expected after opening burr holes and incising the dura matter for Moyamoya disease in adults as well as, possibly, in children.
