Purpose Vertigo is a common presentation to the emergency department (ED) and is often evaluated with high-resolution non-contrast enhanced CT head (HR-NECTH). Superior semicircular canal (SSC) abnormalities, such as thinning (SST) and dehiscence (SSD), are associated with vertigo. Recent work has shown that HR-NECTH that SST/SSD can be detected with similar sensitivity, specificity, and positive/negative predictive values as traditional temporal bone CT exams (TBCT). This study investigates the prevalence of SST/SSD in ED patients presenting with vertigo on HR-NECTH in comparison...
Read more Methods and materials This IRB approved, retrospective study examined ED patients with and without vertigo who received HR-NECTH. Each patient’s SSC was examined using coronal and oblique coronal reformations (Pöschl reformation) to assess the SSC for SST/SSD. Patients were separated into three groups: ED patients without vertigo, ED patients with vertigo but with alternate possible medical/imaging etiologies for their symptoms (explained vertigo), and ED patients with vertigo without alternate etiologies (unexplained vertigo). Patients enrolled in the explained vertigo group demonstrated vertigo in the...
Read more Results One-hundred consecutive ED patients without vertigo, 100 ED patients with explained vertigo, and 100 ED patients with unexplained vertigo were enrolled. The SSC of each patient was examined and interpreted by fellowship trained neuroradiologists (Fig. 1). [fig 1] There was a statistically significant difference in prevalence of SSC abnormalities in ED patients without vertigo (5%, 95% CI [1.3%-10.7%]) compared to ED patients with explained vertigo (16%, 95% CI [8.8%-23.2%]) (P = 0.02) and ED patients with unexplained vertigo (25%, 95 CI...
Read more Conclusion ED patients with vertigo demonstrate increased prevalence of SSC abnormalities on HR-NECTH compared to a control group without vertigo. These results further implicate the relationship between SSC abnormalities and vertigo. Interestingly, there was not a statistically significant difference between the prevalence rates of SSC abnormalities between ED patients with explained and unexplained vertigo. This is likely due to the clinical heterogeneity within the explained vertigo cohort. These findings suggest that ED patients presenting with vertigo should have their SSC evaluated...
