1/76. 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) |
2/76. Cochlear and vestibular dysfunction resulting from physical exertion or environmental pressure changes.Inner ear damage due to physical exertion or environmental pressure changes has been described only recently. According to Goodhill there are two possible mechanisms of injury: the explosive and the implosive. The former is triggered by increased C.S.F. pressure transmitted to the perilymph space; the latter by increased pressure in the middle ear transmitted to the perilymph space through the two windows. Sudden hearing loss or dizziness, or both, are the main symptoms. The diagnosis will be established by the history, the audiogram, and the electronystagmogram (ENG). The treatment is still controversial. As the formation of a fistula is a real possibility, an exploratory tympanotomy is suggestive on suspected cases. Due to the variety of symptoms every case has to be assessed individually. A detailed history is of utmost importance.- - - - - - - - - - ranking = 4.641940895965E-5keywords = injury (Clic here for more details about this article) |
3/76. 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 = 0.3339632544941keywords = carotid (Clic here for more details about this article) |
4/76. 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) |
5/76. 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 = 0.38962379690978keywords = carotid (Clic here for more details about this article) |
6/76. 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 = 0.0034437326724keywords = artery (Clic here for more details about this article) |
7/76. 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 = 0.89243760842142keywords = carotid artery, carotid, artery (Clic here for more details about this article) |
8/76. 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 = 0.07662308224292keywords = carotid, artery, trauma (Clic here for more details about this article) |
9/76. Sigmoid and transverse sinus thrombosis after closed head injury presenting with unilateral hearing loss.Sinus thrombosis has rarely been associated with closed head injury; more often, thrombosis of the sigmoid or transverse sinus is caused by otogenic inflammations or tumours, or occurs during pregnancy. Symptoms are frequently vague, while untreated thrombus progression may be fatal due to venous congestion and infarction. We report a 32-year-old man presenting with right hearing loss, tinnitus and headache 2 days after a closed head injury. Neurological examination showed no additional abnormality. The EEG showed focal bifrontal slowing. CT revealed a fracture of the occipital bone. MRI and MRA demonstrated complete thrombosis of the right sigmoid and transverse sinuses. After 2 weeks of intravenous heparin therapy followed by warfarin, the patient's hearing improved and MRI and MRA showed complete recanalisation of the sigmoid and transverse sinuses. Venous sinus thrombosis can be an undetected sequel to head injury. Appropriate imaging studies should be carried out to enable therapy to be started as soon as possible.- - - - - - - - - - ranking = 0.00032493586271755keywords = injury (Clic here for more details about this article) |
10/76. 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 = 0.0309935940516keywords = artery (Clic here for more details about this article) |
