CT evaluation of unilateral pulsatile tinnitus with jugular bulb wall dehiscence

ConclusionsThe correlating factors of PT with JBWD and PT with SSWD are significantly different. These findings can further facilitate early and efficient PT treatment.Key Points•The incidence of jugular bulb dehiscence (JBWD) accounted for approximately 12.1% in pulsatile tinnitus (PT) patients, and JBWD was established as a causative diagnosis in 5.0% of PT patients.•PT required large blood flows and abnormal flow patterns, whether in JBWD or sigmoid sinus wall dehiscence groups.•JBWD causing PT has some unique characteristic findings on CT.
