In this retrospective case series and literature review, we demonstrate that temporal bone lesions that obstruct the endolymphatic sac or duct can cause symptoms of Ménière's disease. This finding is likely attributable to endolymphatic hydrops; initially, such cases typically masquerade as Ménière's disease. Between July 1995 and April 2002, a total of 379 patients were treated for an initial ...

The aim of this study is to present the five-year longitudinal magnetic resonance imaging (MRI) follow up of a patient with incidental finding of near-obstruction stenosis of the aqueduct of Sylvius due to a large pineal cyst. The patient was scanned 3 times on a 3T MR device using a set of standard structural sequences supplemented with high-resolution constructive interference of steady state...

in this case report, a 36 year old female at 40 weeks' gestation is presented in whom large bilateral vestibular bulb masses were found on pelvic examination. the size of the masses was such as to cause concern that they may pose an impediment to normal parturition. our pathological findings, management and results are presented.

Background: Cochlear implant is an electronic device that stimulates auditory spiral ganglion cells to give persons with hearing loss a sense of sound. 2 primary radiological research studies for cochlear implantation are high-resolution computed tomography (HRCT) & magnetic resonance imaging (MRI). Poor depiction aerated or mineralized structures, major disadvantage using MRI before implantati...

Enlargement of the cochlear aqueduct is a controversial topic, with experienced investigators doubting its existence because of a lack of published cases. We describe the CT appearance of an enlarged cochlear aqueduct in a patient with advanced congenital inner ear anomalies and congenital hearing loss. The intent of this article is to present the CT appearance of a presumably enlarged cochlear...

Background: Pseudo-Pendred syndrome (PPS) is a genetic disorder inherited as an autosomal recessive disorder. PPS characterized by the presence of hypothyroid goiter combined with mild to moderate form SNHL, not presentable at birth, no obvious inner ear malformation. This major difference from Pendred in which SNHL congenital, severe profound nature, and associated malformation, mostly enlarge...

OBJECTIVES/HYPOTHESIS Hearing loss and enlarged vestibular aqueduct (EVA) can be inherited as an autosomal recessive trait caused by mutant alleles of the SLC26A4 gene. In some other families, EVA does not segregate in a typical autosomal recessive pattern. The goal of this study was to characterize the SLC26A4 genotypes and phenotypes of extended families with atypical segregation of EVA. ST...

OBJECTIVES/HYPOTHESIS To determine the distribution of the number and types of mutant alleles of SLC26A4 and their correlations with hearing phenotypes in Korean bilateral enlargement of vestibular aqueduct (EVA) patients. STUDY DESIGN Prospective cohort study. METHODS To determine the number and type of mutant alleles, Sanger sequencing of coding region of SLC26A4 was performed for 56 pati...

OBJECTIVES To determine the prevalence of inner ear anomalies and the frequency of different anomaly types among cochlear implant recipients. METHODS This study included a retrospective chart review of all patients who received cochlear implants between January 2009 and January 2013 in King Abdulaziz University Hospital cochlear implant program in Riyadh, Saudi Arabia. All subjects underwent ...
