Materials and Methods: In a tertiary center, the cranial CT and MRI scans performed between December 2016 and April 2018 were evaluated by a radiologist. The scans that had LVA with any pathology were excluded and those without any pathology were included. Patients who had LVA were contacted over the phone and asked if they had vertigo at the time of the imaging. Patients who had vertigo were asked to answer the Vertigo, Dizziness, Imbalance (VDI) questionnaire over the phone. LVA was classified by the radiologist into grades I, II, and III.
Results: Of the 689 CT and 1018 MRI scans, LVA was detected on 62 (8.9%) and 85 (8.3%), respectively. The mean age was 36.13±12.53, and 50.34% of the patients were women. Of the 83 patients who responded over the phone, 33 (39.7%) had vertigo at the time of the imaging. The mean VDI score was 46.74±11.79. There was a statistically significant and positive linear correlation between age and the LVA grade (p=0.008). The VDI scores were significantly lower in women compared to men, which implies that vertigo is worse in women with LVA (p=0.009).
Conclusion: Vertigo occurs in patients with LVA, and more commonly in women. Age is a factor influencing the LVA grade, but this grade has no influence on vertigo symptoms.
