Hemodynamic Changes in the Sigmoid Sinus of Patients With Pulsatile Tinnitus Induced by Sigmoid Sinus Wall Anomalies

Conclusion: APV, PNV, and RF changes take place in SSWA patients, which may be associated with the occurrence of PT and have the potential value to improve accurate etiological diagnosis and predict treatment success.

Publication date: Available online 15 January 2020Source: Brazilian Journal of OtorhinolaryngologyAuthor(s): Zheng-Cai LouAbstractIntroductionSigmoid sinus diverticulum has been considered the most common cause of pulsatile tinnitus; the mechanism underlying sigmoid sinus diverticulum formation is unclear. To the best of our knowledge, no previous studies have assessed whether the formation of sigmoid sinus diverticulum is related to compression of the internal jugular vein by the styloid process.ObjectiveTo discuss the relationship between the styloid process and the formation of sigmoid sinus diverticulum.MethodsThe medi...

In conclusion, for the radiological assessment of TB fractures, the entire VA should be regarded as a part of the otic capsule, and delayed inner ear sequelae should be anticipated for retrolabyrinthine fracture lines that course into or through the VA. When considering treatment options in cases similar to the present, our findings suggest that surgical interventions targeting the eES (ES shunting/decompression procedures (31–33), which are used in MD with the intention to drain the hydropic endolymphatic fluid space, or to improve the fluid resorptive functions of the eES, respectively, most likely cannot work as p...

In this study, we aimed to elucidate the clinical features, neuroimaging characteristics and pathogenesis of IJVS, and explore their possible correlations, in attempt to provide useful clues for clinical diagnosis and treatment. Forty-three eligible patients with unilateral or bilateral IJVS confirmed by contrast-enhanced magnetic resonance venography of the brain and neck were enrolled in this study. Magnetic resonance imaging along with magnetic resonance angiography or computed tomography angiography was applied to identify the radiological pattern of parenchymal or arterial lesions. Cerebral perfusion and metabolism we...

CONCLUSION: Dural arteriovenous fistula is an uncommon intracranial vascular malformation rarely seen by otolaryngologists, with pulsatile tinnitus being the usual presentation. To our knowledge, this is the first reported case of dural arteriovenous fistula presenting with conductive hearing loss and otalgia. PMID: 30322412 [PubMed - as supplied by publisher]

ConclusionComprehensive neurotological workup results in diagnoses that would go unrecognized otherwise, allowing patients to receive prompt treatment for medically important conditions, some of which may be causally related to their neurotologic complaints. However, the value of each study for routine testing of patients with neurotologic complaints remains controversial; and the evidence presented herein should help practitioners determine what studies should be included in his/her patient assessment.

We describe a 77-year-old man with spontaneous concurrent spinal and cranial SDHs, in whom the spinal SDH was identified 30 days before the intracranial chronic SDH. Diagnosis: Magnetic resonance imaging showed a spinal SDH at L4/L5. There was no paralysis, and the patient was managed conservatively. About 30 days after the onset of back pain, he experienced tinnitus and visual hallucination. Brain computed tomography showed a chronic SDH and midline shift. Interventions: Burr-hole evacuation was performed, and the patient's condition improved. Outcomes: At 5 months of follow-up, there was no recurrence of the spi...

Authors: Li C, Yu J, Li K, Hou K, Yu J Abstract The lateral foramen magnum region is defined as the bilateral occipital area that runs laterally up to the jugular foramen. The critical vasculatures of this region are not completely understood. Dural arteriovenous fistulas that occur in this region are rare and difficult to treat. Therefore, we searched PubMed to identify all relevant previously published English language articles about lateral foramen magnum dural arteriovenous fistulas, and we performed a review of this literature to increase understanding about these fistulas. Four types of dural arteriovenous fi...

The jugular bulb is a venous structure linking the sigmoid sinus with the internal jugular vein. Jugular diverticulum is a rare condition characterized by extraluminal outpouching from the jugular bulb. As the patients may be totally asymptomatic, but sensorineural symptoms such as sensorineural hearing loss, tinnitus and vertigo can also occur. Diagnosis of these patients can be made by some radiologic methods such as high-resolution computerized tomography, magnetic resonance imaging, or a novel radiologic technique flat panel computed tomography. In this paper we report a 22-year-old female patient with jugular divertic...
