1/46. An aneurysm of the petrous internal carotid artery.Internal carotid artery aneurysms are a rare cause of pulsatile tinnitus and conductive hearing loss but should be borne in mind when there is a suspected diagnosis of glomus jugulare or high-riding jugular bulb. Most cases are congenital. We present a case of otorrhagia which was initially thought to be a glomus jugulare, the diagnosis of internal carotid artery aneurysm was made at angiography and treated by balloon embolization.- - - - - - - - - - ranking = 1keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
2/46. Reversible sensorineural hearing impairment induced by a carotid body tumor.A case of a 62-year-old Austrian man having a 25-year history of a right-sided carotid body tumor (CBT) is presented. Three months before being transferred to the University of Vienna for tumor resection the patient developed symptoms of tinnitus, progressive ipsilateral hearing loss and dysphagia. Pure-tone audiometry demonstrated a 50 dB right sensorineural hearing loss. A 6 x 6 x 4 cm firm, pulsatile mass was found in the right carotid triangle and extending towards the base of the skull. One week after radical tumor resection all preoperative symptoms disappeared and hearing of the right ear recovered. review of the available literature showed that hearing loss and tinnitus are unusual symptoms of a CBT. Our findings suggest that routine audiometric evaluations in such cases of CBT patients should be obtained in order to determine the real incidence of audiological disorders.- - - - - - - - - - ranking = 0.47129863636072keywords = carotid (Clic here for more details about this article) |
3/46. Aberrant internal carotid artery in the middle-ear space.The incidence of an aberrant internal carotid artery in the middle ear is approximately one per cent and most patients are asymptomatic. We present two patients with an aberrant internal carotid artery who presented with pulsatile tinnitus and an intra-tympanic mass. Here we discuss the clinical presentation, relevant radiographic investigations and further management of these patients.- - - - - - - - - - ranking = 1keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
4/46. Indirect carotid cavernous fistula presenting as pulsatile tinnitus.This paper reports a case of spontaneous indirect carotid cavernous fistula that presented with pulsatile tinnitus, left-sided temporal headache and left-sided ptosis. The pulsatile tinnitus, its aetiology and investigation are discussed. The importance of pulsatile tinnitus is highlighted, with a discussion of carotid-cavernous fistulas. This case illustrates that clinically silent cavernous sinus thrombosis can give rise to spontaneous indirect carotid cavernous fistula. magnetic resonance imaging angiography was used in diagnosis. Treatment ranges from observation, as in our case, to transvenous endovascular techniques.- - - - - - - - - - ranking = 0.54984840908751keywords = carotid (Clic here for more details about this article) |
5/46. Unique case of pulsatile tinnitus.tinnitus is a common symptom encountered by otolaryngologists. Pulsatile tinnitus is rare and can present a diagnostic challenge. Establishing a diagnosis is important, because pulsatile tinnitus may indicate serious intracranial or extracranial disease. A unique case of pulsatile tinnitus caused by cervical artery dissection is presented, along with the differential diagnosis and treatment.- - - - - - - - - - ranking = 0.0027331160290857keywords = artery (Clic here for more details about this article) |
6/46. Lateralized carotid artery: an unusual cause of pulsatile tinnitus.We describe the case of a patient who had a pulsatile tinnitus that was caused by a laterally displaced internal carotid artery. Her condition was treated with the use of a hearing did, which suppressed the tinnitus. We also review the literature on laterally displaced internal carotid arteries, and discuss their differentiation from a congenitally aberrant artery.- - - - - - - - - - ranking = 0.91461622208921keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
7/46. tinnitus caused by traumatic posterior auricular artery--internal jugular vein fistula.A patient with an arteriovenous fistula that developed after a traffic accident was recently treated. The patient noticed pulsatile tinnitus in the right orbital region two months after the accident. On the first visit, the preliminary clinical impression of this case was a carotid-cavernous fistula, but angiography showed a fistula between the posterior auricular artery and the internal jugular vein. Although rare, this arteriovenous fistula should be included in the differential diagnosis of pusatile tinnitus in the orbit region. The fistula was controlled by embolization with a platinum coil. This is the first report of an arteriovenous fistula between the posterior auricular artery and internal jugular vein.- - - - - - - - - - ranking = 0.094948468901301keywords = carotid, artery (Clic here for more details about this article) |
8/46. Bilateral sudden deafness as a prodrome of anterior inferior cerebellar artery infarction.BACKGROUND: Acute ischemic stroke in the distribution of the anterior inferior cerebellar artery is known to be associated with hearing loss, facial weakness, ataxia, nystagmus, and hypalgesia. There have been few reports on bilateral deafness and vertebrobasilar occlusive disease. Furthermore, previous reports have not emphasized the inner ear as a localization of bilateral deafness. OBJECTIVE: To describe the presentation of acute ischemic stroke in the distribution of the anterior inferior cerebellar artery as sudden bilateral hearing loss with minimal associated signs. DESIGN AND SETTING: Case report and tertiary care hospital. PATIENT: A 66-year-old man with diabetes mellitus developed sudden bilateral deafness, unilateral tinnitus, and vertigo 7 days before the onset of dysarthria, facial weakness, and ataxia. T2-weighted magnetic resonance imaging scans showed hyperintensities in the right lateral pons and right middle cerebral peduncle and a possible abnormality of the left middle cerebellar peduncle. A magnetic resonance angiogram showed moderately severe stenosis of the distal vertebral artery and middle third of the basilar artery. The patient's right limb coordination and gait improved steadily over several weeks, but there was no improvement in hearing in his right ear. CONCLUSIONS: The relatively isolated onset of deafness as well as the severity and persistence of the hearing loss led us to conclude that the hearing loss in this case was likely due to prominent hypoperfusion of the internal auditory artery, with labyrinthine infarction as the earliest event. Vertebrobasilar occlusive disease should be considered in the differential diagnosis of sudden bilateral deafness.- - - - - - - - - - ranking = 0.024598044261771keywords = artery (Clic here for more details about this article) |
9/46. Therapeutic embolization of the dural arteriovenous malformation involving the jugular bulb.Pulsatile tinnitus is a rarely occurring symptom of vascular origin. Most frequently, the symptoms are due to an arteriovenous malformation, to a tumor of the jugular glomus or to a local arterial stenosis. A 39-yr-old Korean male suffering from pulsatile tinnitus of the left ear was diagnosed to have dural arteriovenous malformation of the jugular bulb. magnetic resonance imaging and angiography revealed a high-velocity vascular lesion encroaching the internal jugular vein and sigmoid sinuses. Digital subtraction angiography demonstrated a dural arteriovenous malformation involving the jugular bulb. The arterial supply was from the neuromeningeal branch of the left ascending pharyngeal artery and inferior tympanic artery. Stenosis of the left jugular vein caused retrograde venous drainage through the contralateral transverse sinus. Superselective embolization of these feeding arteries was successfully performed using 25% mixture of N-butylcyanoacrylate and lipiodol. In postembolization period, his complaints of pulsatile tinnitus and buzzing noise behind his left ear disappeared.- - - - - - - - - - ranking = 0.0054662320581714keywords = artery (Clic here for more details about this article) |
10/46. cerebellopontine angle epidermoid tumor presenting with 'tic convulsif' and tinnitus--case report.A 22-year-old female presented with a cerebellopontine angle epidermoid tumor manifesting as a rare combination of hemifacial spasm, trigeminal neuralgia, and tinnitus. magnetic resonance imaging demonstrated the tumor distorting the brainstem and the fourth ventricle. The tumor was almost completely resected and the seventh-eighth cranial nerve complex was decompressed by mobilizing the anterior inferior cerebellar artery loop. No arterial loop was related to the trigeminal nerve. The patient was completely relieved of the "tic convulsif" and tinnitus after the surgery. The inflammatory nature of epidermoid tumor may be involved in the etiology of the syndrome. Microvascular decompression may be needed in addition to tumor removal in such cases.- - - - - - - - - - ranking = 0.0027331160290857keywords = artery (Clic here for more details about this article) |
