1/38. moyamoya disease of adult onset brain stem haemorrhage associated with bilateral occlusion of the vertebral arteries--case report.An unusual and first case of moyamoya disease of adult onset brain stem haemorrhage associated with occlusion of both vertebral arteries is reported. A 30-year-old man suddenly suffered from dyspnea, dysphagia, and left-sided hemisensory disturbance. Computed tomography and magnetic resonance imaging revealed a fresh haematoma in the left medulla oblongata and various-sized old infarcts in both parietal lobes. Cerebral angiograms disclosed occlusion of the bilateral internal carotid arteries on both sides at their intracranial portion, accompanied with the developed basal moyamoya vessels. The right vertebral artery occluded at its V2-V3 segment, in which the posterior inferior cerebellar artery was opacified via the posterior spinal artery, and the basilar artery was filled from the anterior spinal artery. The left vertebral artery was also occluded at the craniovertebral junction (V4) with collateral flow. Only one case of moyamoya disease associated with bilateral occlusion of the vertebral artery has been reported previously, and a haemorrhage into the medulla oblongata in moyamoya disease has never been described.- - - - - - - - - - ranking = 1keywords = haemorrhage (Clic here for more details about this article) |
2/38. radiation-induced aneurysm and moyamoya vessels presenting with subarachnoid haemorrhage.A rare case of a ruptured internal carotid artery (ICA) aneurysm, with ICA stenosis and moyamoya vessels, was diagnosed in a young female patient after radiotherapy for optic glioma. Retrospective analysis revealed that an extraordinarily high dose of radiation (110 Gy) had been delivered to the area around the ICA in two therapeutic sessions. Clipping and wrapping of the aneurysm were performed and the patient made a good recovery. A review of the literature suggested that rupture of radiation-induced aneurysms is a rare event, but may be fatal. Considerable care must therefore be taken when delivering high-dose radiation to cerebral arteries. We suggest that the incidence of radiation-induced moyamoya vessels is higher in younger patients.- - - - - - - - - - ranking = 6.5594438419049keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
3/38. Moyamoya-like vasculopathy from cocaine dependency.We herein describe two cases of moyamoya vasculopathy occurring in two men who used alkaloidal cocaine for years. One patient presented with aneurysmal subarachnoid hemorrhage and one with infarction in both lobes. Particularly impressive was a significant degree of collateral development with lenticulostriate networks.- - - - - - - - - - ranking = 0.23969094342683keywords = subarachnoid (Clic here for more details about this article) |
4/38. Terson syndrome caused by ventricular hemorrhage associated with moyamoya disease--case report.A 24-year-old female presented with Terson syndrome secondary to bilateral ventricular hemorrhage as a complication of moyamoya disease. ophthalmoscopy and magnetic resonance imaging clearly demonstrated vitreous hemorrhage in the left eye globe. Various visual symptoms are associated with moyamoya disease, almost all of which result from ischemic lesions in the visual cortex and optic pathways. In this case, the visual disturbance was caused by Terson syndrome secondary to ventricular hemorrhage. Close ophthalmological and radiological evaluation is mandatory even in patients with moyamoya disease and hemorrhagic manifestation located in the intracerebral, subarachnoid, or intraventricular space.- - - - - - - - - - ranking = 0.23969094342683keywords = subarachnoid (Clic here for more details about this article) |
5/38. Endovascular treatment of basilar tip aneurysm associated with moyamoya disease--case report.A 58-year-old female was admitted unconscious to a local hospital. Computed tomography demonstrated subarachnoid hemorrhage. cerebral angiography revealed evidence of moyamoya disease and a saccular aneurysm at the tip of the basilar artery. The patient was transferred to our hospital for embolization of the basilar tip aneurysm. Endovascular embolization was performed using Guglielmi detachable coils (GDCs), and the aneurysm was completely occluded with preservation of the parent artery. No change in the patient's neurological status was seen during and after the procedure. Endovascular treatment using GDCs appears to be particularly suitable for ruptured cerebral saccular aneurysms in patients with moyamoya disease.- - - - - - - - - - ranking = 0.23969094342683keywords = subarachnoid (Clic here for more details about this article) |
6/38. Spontaneous middle cerebral artery occlusion leading to moyamoya phenomenon and aneurysm formation on collateral arteries.BACKGROUND: Spontaneous middle cerebral artery occlusion associated with moyamoya phenomenon is distinct from moyamoya disease. The hemodynamic stress on the collateral channel occasionally leads to aneurysm formation, which may manifest as hemorrhage. The etiology of this disease has not been fully understood. CASE DESCRIPTION: A 63-year-old woman presented with left putaminal hemorrhage. The cerebral angiogram revealed a significant stenosis in the proximal segment of the left middle cerebral artery. Collateral arteries originating from the horizontal segment of the ipsilateral anterior cerebral artery and the ambient segment of the ipsilateral posterior cerebral artery supplied the middle cerebral artery distal to the stenosis. Both of the collateral channels had associated aneurysms that were surgically obliterated. The aneurysm on the collateral artery from the posterior cerebral artery was responsible for the putaminal hemorrhage. CONCLUSIONS: Spontaneous middle cerebral artery occlusion may lead to focal moyamoya phenomenon and aneurysmal intracerebral, intraventricular, or subarachnoid hemorrhage. The presence of a co-existing anomalous collateral artery in the present case suggests a congenital etiology of the focal middle cerebral artery occlusion.- - - - - - - - - - ranking = 0.23969094342683keywords = subarachnoid (Clic here for more details about this article) |
7/38. Secretory meningioma associated with numerous meningothelial rosettes.A case of secretory meningioma with numerous meningothelial rosettes is reported. A 66-year-old man with moyamoya disease gradually developed skull deformity, and underwent surgery for the skull tumor overlying the hemisphere. Histological examination disclosed numerous meningothelial rosettes quite similar to those induced by subarachnoid injection of epinephrine and pseudopsammoma bodies described by Kepes. This may be the first case of meningioma associated with numerous rosette formations.- - - - - - - - - - ranking = 0.23969094342683keywords = subarachnoid (Clic here for more details about this article) |
8/38. Endovascular treatment of posterior cerebral aneurysm associated with moyamoya disease.PURPOSE: A patient with moyamoya disease associated with a ruptured posterior cerebral artery aneurysm treated by endovascular embolization is presented. CASE REPORT: A 47-year-old woman was admitted with severe headache to our hospital. Computed tomography demonstrated subarachnoid haemorrhage. cerebral angiography revealed evidence of moyamoya disease and a saccular aneurysm at the P1 segment of the left posterior cerebral artery. CONCLUSION: Endovascular embolization was performed using Guglielmi detachable coil (GDC), and the aneurysm was completely occluded with preservation of the parent artery. Endovascular treatment using GDC seems comparatively safe and effective for the treatment of cerebral saccular aneurysms in patients with moyamoya disease.- - - - - - - - - - ranking = 1.6398609604762keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
9/38. moyamoya disease complicated by life-threatening epistaxis: first report of a case.OBJECTIVE: Subacute haemorrhage is a common emergency in otorhinolaryngology. Rapid evaluation of the aetiology and localization is a precondition for suitable treatment. We demonstrate a rare case of primarily intractable epistaxis associated with occlusion of the circle of willis (moyamoya disease). PATIENT: A 38-year-old man presented with a 24-h history of recurrent epistaxis. Anamnesis revealed long-term anticoagulation after heart valve transplantation and arterial hypertension. RESULTS: As a result of several re-bleedings after anterior nasal packing, a re-packing was followed by surgical treatment under general anaesthesia. Four days after discharge the patient presented to the intensive care unit with severe re-bleeding. After removal of a temporary Bellocq packing, interdisciplinary treatment was necessary. Emergency angiography revealed advanced moyamoya disease, with occlusion of both internal carotid arteries. The cerebral blood supply was sustained by an excessive collateral network originating from external carotid anastomoses. This complicated the endovascular treatment, which consisted of embolization of the infraorbital and maxillar arteries with liquid material and coils flanked by Bellocq packing. The patient was doing well at follow-up after 12 months. CONCLUSION: epistaxis complicating moyamoya disease is rare, and endovascular treatment is difficult due to the high risk of cerebral embolism. Malformations of the cerebral arteries should be considered in the differential diagnosis of intractable epistaxis.- - - - - - - - - - ranking = 0.16666666666667keywords = haemorrhage (Clic here for more details about this article) |
10/38. Hemorrhage from moyamoya-like vessels associated with a cerebral arteriovenous malformation. Case report.The authors describe a case of subarachnoid hemorrhage from moyamoya-like vessels associated with an arteriovenous malformation (AVM) in a 44-year-old Hispanic man who presented with severe headache. The AVM was located in the left parietal lobe and the ipsilateral middle cerebral artery was occluded. Although the patient was initially neurologically intact, he began to experience neurological deficits from mild vasospasm, illustrating the sensitivity of the underperfused portion of brain surrounding an AVM. His neurological deficits improved with aggressive hydration and elevated blood pressure. After a 3-week period, the AVM was resected without complication and all of the patient's neurological deficits resolved. The authors review radiographic findings of this unique case.- - - - - - - - - - ranking = 0.23969094342683keywords = subarachnoid (Clic here for more details about this article) |
