1/11. Symptomatic unruptured capillary telangiectasia of the brain stem: report of three cases and review of the literature.Three young patients with transient or intermittent focal neurological signs suggesting brain stem involvement are described, in whom high field MRI showed focal areas of hyperintensity in T2 weighted spin echo images, hypointensity in T2* weighted gradient echo images, and enhancement in postcontrast T1 weighted images consistent with unruptured capillary telangiectasia of the brain stem. The first patient was a 28 year old woman who complained of recurrent left ear tinnitus, exacerbated during the menstrual period; MRI demonstrated that the vascular anomaly involved the left acoustic pathway. The second patient was a 30 year old woman who had three episodes of paroxysmal left lip movement 4 weeks after child delivery; MRI showed capillary telangiectasia in the right corticonuclear pathway. The third patient, a 36 year old man, had a transient right Bell's palsy; MRI disclosed two circumscribed areas consistent with capillary telangiectasia in the left corticospinal tract and medial longitudinal fasciculus. Steroid receptors in the telangiectatic vessels walls might account for the recurrent and transient course seen in our two female patients. awareness of the MRI features of capillary telangiectasia may help in defining the real incidence, clinical correlation, and the risk of haemorrhagic complications of these vascular malformations.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/11. Extra cranial arteriovenous malformations presenting as pulsatile tinnitus.We present two cases of extra cranial arteriovenous malformations, which presented as pulsatile tinnitus. They were originally diagnosed by clinical examination and both lesions were subsequently confirmed by angiography and their feeding vessels defined. One case was managed by surgical excision, which produced relief of symptoms. The diagnosis and management of arteriovenous malformations is discussed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/11. Endovascular treatment of a transverse-sigmoid sinus aneurysm presenting as pulsatile tinnitus. Case report.The authors report on the case of a 38-year-old woman who had experienced incapacitating pulsatile tinnitus in the left ear for 6 months. Angiographic studies revealed a wide-necked venous aneurysm of the left transverse-sigmoid sinus. Solitary stent placement across the aneurysm neck resulted in a slight modification in the lesion's characteristics. A second session, in which embolization with Guglielmi Detachable Coils was performed, resulted in a 100% occlusion of the aneurysm, with patency of the parent vessel and resolution of the tinnitus.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/11. A new therapeutic procedure for treatment of objective venous pulsatile tinnitus.Pulsatile tinnitus usually means a turbulent flow within the vessels. We describe a 54-year-old man with a disabling objective pulsatile tinnitus due to a diverticulum of the sigmoid sinus toward the ipsilateral mastoid. We performed a surgical intervention via the endovascular route using coils to obliterate the diverticulum and a stent to avoid coil migration. The patient had a complete and immediate remission of the pulsatile tinnitus. This procedure has been described only in arterial circulation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/11. giant cell arteritis with CD8 instead of CD4 T lymphocytes as the predominant infiltrating cells in a young woman.giant cell arteritis is rarely reported in people aged less than 50 years. We report a case of giant cell arteritis in a woman who developed symptoms of dizziness, headache, bilateral sensorineural hearing impairment, and had 1 episode of transient left hemiparesis before the age of 30. Carotid angiography showed multiple segmental narrowing in cranial vessels. Subsequently, at the age of 31, she had weight loss and developed a fever. Chest radiograph revealed mediastinal widening, and chest computed tomography revealed dilated pulmonary arteries and veins. coronary angiography and aortography showed irregular narrowing of the descending aorta and multiple stenosis, with aneurysmal dilatation involving the proximal and distal coronary, pulmonary and mesenteric arteries. Multinucleated giant cells and predominant CD8 T lymphocyte infiltration were noted in a left temporal artery biopsy specimen. The patient's age and the finding of dilated pulmonary veins and prominent CD8 T lymphocytes in the biopsy specimen suggest that this case was a distinct form of systemic giant cell arteritis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/11. Tympanic paragangliomas: case reports.Glomus tumors, also called paragangliomas, originate from nonchromaffin cells. The tumor is typically vascular and grows from capillary and pre-capillary vessels in-between epithelial cells. It is worth mentioning that the most common symptoms are pulsating tinnitus and hearing loss. Imaging studies (CT and MRI) are necessary for diagnosis. This paper shows five patients seen at the Hospital between 1995 and 2001 presenting glomus tympanicum. women were most commonly affected, and the age ranged from 48 to 60 years (mean age of 50 years). The most common complaints were pulsating tinnitus and hearing loss. All patients were treated surgically.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/11. diagnosis and cure of venous hum tinnitus.Sounds arising from abnormalities of or abnormal communications between blood vessels in the neck or cranial cavity may result in objective tinnitus. It is audible to patient and examiner alike. Contrary to the usual subjective tinnitus of non-vascular origin, it is low pitched and pulsatile in character. That tinnitus which arises from and within the internal jugular vein is particularly important, as it may be loud enough to interfere with sleep, and result in some loss of hearing. diagnosis is important as it can be cured by simple ligation of the internal jugular vein. Such a case is reported.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/11. A cochlear vascular anomaly in a patient with hearing loss and tinnitus.An unusual blood vessel in the cochlea of a patient is reported. The blood vessel derives from the osseous lamina spiralis and crosses straight through the scala tympani toward the lateral wall of the perilymphatic duct. In its course a branch derives from this vessel toward the other spiral vessel. In the region of this abberrant vessel a complete hair-cell loss is present. A high tone perceptive loss with a relative dip and tinnitus was found in the same ear during life. The possible cause and effects of this abberrant vessel are discussed.- - - - - - - - - - ranking = 6keywords = vessel (Clic here for more details about this article) |
9/11. Macrovascular causes underlying otoneurological disturbances.In the diagnostic procedure for patients with symptoms and signs indicating VIIIth nerve or brain stem disturbances, the possible presence of tumors, infarcts, bleedings or microvascular loops are taken into account. Ten patients with vertigo, balance disorders, tinnitus or unilateral hearing loss proved to have a similar cause underlying the disturbances. They ranged in age from 51 to 80 years and had a duration of their symptoms of 1-10 years. In the test battery audiology, electronystagmography, broad-frequency rotatory testing and dynamic posturography were used. No uniform pattern was present. The results showed VIIIth nerve as well as CNS signs. trigeminal neuralgia and hemifacial spasm were observed. CT, NMR or angiography were performed. The common finding for these patients were ectatic vertebral and/or basilar arteries. The size and position of the vessels indicated that compression of the VIIIth nerve or brainstem was the cause underlying their disturbances. To exclude that macrovessels appear in patients without neurotological symptoms and signs 300 consecutive NMR investigations in patients referred for other than neurotogic indications were scrutinized. In these patients no macrovessels were found. The findings indicate that ectatic vessels may cause disturbances mimicking a pontine angle tumor, Meniere's disease and other peripheral or central conditions with inner ear symptoms, vertigo and balance disorders. Arterial loops in the pontine angle may give indications for microvascular surgery, but the big ectatic vertebral and basilar arteries may offer surgical decompression possibilities, though with large risks.- - - - - - - - - - ranking = 4keywords = vessel (Clic here for more details about this article) |
10/11. Microangiopathy of brain, retina, and inner ear.Microangiopathy of brain, retina, and inner ear is a rare syndrome manifesting as arteriolar occlusions of the brain, retina, and inner ear, with resultant encephalopathy, visual, and hearing loss. Despite exhaustive laboratory examinations in these patients, no evidence of a systemic disease can be found. We treated and followed an adolescent with this disorder who initially presented with a branch retinal artery occlusion. A unique finding in this case was retinal vessel wall hyperfluorescence noted five days prior to retinal infarction. The patient developed recurrent branch artery occlusions, sensorineural hearing loss, and central nervous system infarctions despite anticoagulation and immunosuppressive treatment.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
