Abstract OBJECTIVE AND IMPORTANCE: Arteriovenous malformations in the cranial nerves are very rare, and only one case has been reported in the literature. To our knowledge, this is the first case report of an arteriovenous malformation in the auditory nerve. CLINICAL PRESENTATION: A 30-year-old woman presented with a subarachnoid hemorrhage resulting from rupture of an arteriovenous malformation in the auditory nerve. INTERVENTION: During the operation, the auditory nerve bundle was found to be severely damaged and a nidus was identified inside the bundle. CONCLUSION: Although arteriovenous malformations are thought to arise in the 4th to 8th weeks of gestation, this case might indicate a more specific time of emergence based on embryogenesis of the cranial nerves.

Background and objective One of the treatment options for arteriovenous malformations consists of embolization, with a choice of various embolic agents, with or without subsequent surgical excision. If embolization is offered without subsequent surgery, the embolic material will stay in situ, in which case the consistency and color become important in superficial lesions. The purpose of this case report is to describe if the use of a novel liquid embolic agent (PHIL) is well suited for treatment of superficial AVMs without subsequent surgery. Case description A 30-year-old male presented with a painful reddish, pulsatile swelling of the left ear that had been present for more than 10 years. Angiography confirmed an arteriovenous malformation supplied by the superficial temporal artery and the posterior auricular artery. The lesion was successfully treated by embolization with PHIL, through the superficial temporal artery. A minute residual shunt, from the posterior auricular artery, was accepted. Immediate disappearance of pulsatile tinnitus was reported. Moreover, return of normal skin color was observed without discomfort from the embolic deposits. This result has been stable throughout one year of clinical follow-up. Conclusion To our knowledge, this is the first case report describing PHIL embolization as a treatment option for superficial arteriovenous malformations without the necessity for subsequent surgery. The white color and rubbery consistency are beneficial characteristics of PHIL in treatment of subcutaneous lesions, especially in cosmetically relevant locations.

First Case

AbstractCongenital arteriovenous malformations are rare causes of congestive cardiac failure in neonates. The most common sites are in the head and liver, but other sites include the thorax, the abdomen and the limbs. The onset of failure is usually not in the immediate neonatal period, but later on in life, albeit that lesions such as the arteriovenous malformation of the vein of Galen, and other arteriovenous malformations in different locations which produce high flow can present early. We describe here the first case, to the best of our knowledge, of prenatal detection of an intrathoracic arteriovenous malformation producing neonatal cardiac failure, which was successfully treated by surgery postnatally.

Intratumoral Bleeding

AbstractVestibular schwannomas (VSs) account for ∼ 70% of all tumors of the cerebellopontine angle (CPA). Their clinical presentation is often insidious, with progressive hearing loss and involvement of other cranial nerves. Spontaneous hemorrhage in those tumors is very unusual, and generally presents with acute clinical features such as nausea, vomiting, headache and altered consciousness, usually with marked dysfunction of the cranial nerve involved, and with new deficits of neighboring cranial nerves. Asymptomatic patients are extremely rare. We present a case report of an incidental VS with asymptomatic bleeding, which evolved to death after surgery.

Introduction. Familial arteriovenous malformations are exceedingly rare. They are often noted at birth. They can also present during childhood or adolescence. Sclerotherapy has proven to have a favorable outcome. Case Presentation. The present case report describes the treatment of arteriovenous malformations on the tongue, labial mucosa, and vermilion border in siblings treated with boiling saline injections. Conclusion. Sclerotherapy using boiling saline had shown to effectively treat arteriovenous malformations in the oral region without any significant morbidity.

Perimedullary spinal AVM is a rare type of spinal arteriovenous malformations. We present a case of 70 yrs female who presented with motor weakness in her bilateral limbs. Initial MRI was misinterpreted as ependymal myxoma; however, histopathology revealed spinal AVM. MRA or DSA should be conducted if AVM is suspected.

Disease Case

Abstract A 25-year-old man was hospitalized after suffering a subarachnoid hemorrhage. Arteriograms disclosed two arteriovenous malformations, one of which was asymptomatic. Rendu-Osler-Weber disease was suspected because of the concomitant existence of cutaneous telangiectases, Review of the literature shows that in 12 previously published cases involving multiple arteriovenous malformations, this diagnosis was established five times. The indications for surgical treatment are discussed.

ABSTRACT BACKGROUND AND IMPORTANCE The Coupler microanastomotic device (Medical Companies Alliance, Birmingham, Alabama) aims at facilitating safe and efficient end-to-end reconstruction of the native vessel ends following resection of intracranial aneurysms. CLINICAL PRESENTATION We report the first case of the Coupler device used to treat a ruptured posterior inferior cerebellar artery (PICA) aneurysm. Following aneurysmal trapping and excision, the native parent vessel ends were connected in an end-to-end fashion. CONCLUSION The microanastomotic Coupler device is an acceptable option for end-to-end anastomosis and was successfully applied in the management of a ruptured fusiform PICA aneurysm.

Abstract OBJECTIVE: The rostral ventrolateral medulla is thought to serve as a final common pathway for the integration of central cardiovascular information and to be important for the mediation of central pressor responses. An association between essential hypertension and neurovascular compression of the rostral ventrolateral medulla has been reported. This may be mediated by an increase in sympathetic tone. CLINICAL PRESENTATION: Schwannomas arising from the lower cranial nerves (Cranial Nerves IX-XI) are rare, constituting only 3% of all intracranial schwannomas unassociated with neurofibromatosis. The majority of these tumors present as jugular foramen lesions and, less commonly, they occur along the extracranial course of these nerves. An intracisternal location is extremely rare. Fewer than 15 cases of pathologically proven intracisternal vagal schwannomas in the absence of neurofibromatosis have been reported. INTERVENTION: We report a case of vagal schwannoma in the cerebellomedullary cistern causing distortion of the vagal root entry zone and presenting with refractory neurogenic hypertension. Total microsurgical excision of this tumor, arising from one of the rootlets of the vagus nerve, was achieved. Immediately postoperatively, blood pressure decreased markedly, and despite our effort to maintain the blood pressure with fluids, the patient developed a cerebral infarction in the watershed zone. CONCLUSION: We discuss the proposed mechanism of hypertension, and the perioperative management, stressing blood pressure control. A review of the literature regarding vagal schwannomas is also presented. To the best of our knowledge, this is the first case report of a cerebellomedullary cistern vagal schwannoma presenting with neurogenic hypertension.
