Posterior semicircular canal dehiscence syndrome (PSCD) is the presence of vestibuloauditory symptoms secondary to absence of the bony covering of the posterior semicircular canal (PSC).
It is thought to be rare: in a case series of 112 patients with a high riding jugular bulb it was found in only four patients (~4%).
Vertigo has been found in a number of cases of posterior semicircular canal dehiscence although a causal link remains contentious 1.
Treatment and prognosis
Optimal management remains to be determined. Prognosis is unknown.
