Posterior semicircular canal cupulolithiasis during acute pontomedullary demyelination

Practical Neurology, 2023
Positional vertigo poses a diagnostic challenge in people with multiple sclerosis (MS). The characteristics of positional nystagmus and its response to repositioning manoeuvres are usually sufficient to diagnose benign paroxysmal positional vertigo (BPPV).

Dehiscence of the posterior semicircular canal

American Journal of Otolaryngology, 2015
Semicircular canal dehiscence (SCD) is a condition of the inner ear wherein the temporal bone adjacent to the vestibular apparatus thins or erodes completely. It has no clear epidemiological predisposing factors that have been identified to date. Its diagnosis is made difficult by a clinical presentation that often overlaps with other pathologies of ...

Congenital Dehiscence in the Posterior Semicircular Canal

Otology & Neurotology, 2013
Posterior semicircular canal dehiscence (PSCD) may be of congenital origin.PSCD is characterized by the lack of bone coverage, which results in its lumen being exposed to the meninges of the posterior cranial fossa or to the gulf of the jugular vein. It has an incidence of 0.2%.

Radiological patterns of the posterior semicircular canal

Surgical and Radiologic Anatomy, 2013
The identification and definition of the radiological patterns of the posterior semicircular canal (PSC), with a view to obtain readily applicable conclusions.The parietal morphology of the PSC has been studied by multi-slice helical computed tomography (Philips Brilliance 6).

Posterior semicircular canal dehiscence in asymptomatic ears

Acta Oto-Laryngologica, 2010
This study revealed that, in the adult population, the final diagnosis of this entity can only be made by combining imaging with clinical tests.We developed the largest temporal bone multislice computed tomography (CT) scan study so far by including 410 cases to investigate the prevalence of posterior semicircular canal dehiscence in patients with ...

Particulate Matter in the Posterior Semicircular Canal

The Laryngoscope, 1997
AbstractThe pathoetiology of benign paroxysmal positional vertigo (BPPV) is controversial. Particulate matter within the posterior semicircular canal has been identified intraoperatively in patients with BPPV but has also been reported in non‐BPPV patients at the time of translabyrinthine surgery (Parnes LS, McClure JA.

Canalith repositioning procedure improves gait and static balance in people with posterior semicircular canal benign paroxysmal positional vertigo

Journal of Vestibular Research-Equilibrium & Orientation, 2020
BACKGROUND: Investigations measuring gait tests have rarely been studied in the benign paroxysmal positional vertigo (BPPV) population. OBJECTIVE: Examine instrumented mobility metrics in people with posterior semicircular canal BPPV.

Posterior semicircular canal dehiscence: a morphologic cause of vertigo similar to superior semicircular canal dehiscence

European Radiology, 2003
The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear.
