OBJECTIVE To determine whether congenital cytomegalovirus (CMV) infection is an etiologic factor in the pathogenesis of enlarged vestibular aqueducts (EVA). DESIGN Two different cohort studies. Subjects The study population comprised 19 subjects with a history of congenital CMV infection and sensorineural hearing loss (cohort 1); 39 subjects with nonsyndromic EVA and their unaffected mothers ...

Intracranial pressure is normally transmitted to the perilymph of the cochlea via the cochlear aqueduct. The relationship between perilymphatic pressure, indirectly measured by tympanic membrane displacement, and mean intracranial pressure defined either clinically or by direct measurement has been examined in 58 patients (aged 5-77 years), with hydrocephalus, benign intracranial hypertension, ...

Large Vestibular Aqueduct Syndrome (LVAS) is the most common radiographic malformation in children with early onset of hearing loss. Usually its occurrence is non-familial, however intriguingly a portion of patients with LVAS is found to have evidence of genetic predisposition. We described cases of LVAS in two siblings of a Chinese family. The elder sister first presented with reduced hearing ...

BACKGROUND A large vestibular aqueduct (LVA) is the most common inner ear anomaly found on the imaging evaluation of children with sensorineural hearing loss (SNHL). It is frequently associated with syndromic and nonsyndromic forms of SNHL or as an isolated finding. Large vestibular aqueduct syndrome can be characterized by delayed-onset, fluctuating, asymmetric, unilateral or bilateral SNHL or...

Vascular compression as the cause of aqueductal stenosis is rare. In a 16-year-old girl with hydrocephalus, MR imaging provided evidence of aqueductal stenosis caused by a venous angioma in the tectum and midbrain. This indicates the usefulness of MR imaging for the evaluation of obstructive hydrocephalus.

Wernicke encephalopathy is a disease usually related to chronic alcoholism. The clinical diagnosis is often difficult to establish, and CT is unable to provide specific findings. MR follow-up studies in five patients affected by Wernicke encephalopathy were performed with the aim of establishing the sensitivity of MR in depicting the typical diencephalic/mesencephalic lesions. All subjects had ...

The fourth- and fifth-century aqueduct system of Constantinople is, at 426 km, the longest water supply line ancient world. Carbonate deposits i659ide an archive both archaeological developments palaeo-environmental conditions during depositional period. 246-km-long from fourth century used springs a small aquifer, whereas 180-km-long extension to west tapped larger aquifer. Although historical...

Abstract Background The most common radiologically detectable congenital inner ear anomaly is an enlarged vestibular aqueduct (EVA), which associated with varying degrees of hearing loss and disorders. purpose this study was to ascertain the incidence in hearing-impaired children sent a tertiary care referral center, as well describe audiologic pattern EVA those individuals. Results In retrospe...
