Aim of Study: To assess a subgroup analysis of patients of abnormal posterior circulation with respect to their MRA. Methods: This was an observational cross-sectional study, consisting of consecutive more than 18 years patients presenting as isolated vertigo of any duration admitted in department of Neurology in Sri Aurobindo Institute of Medical Sciences Indore (MP), India. Results: Total 23 patients were included in the study who met the inclusion criteria. 47.8% cases were found to have abnormal MRA of brain, while remaining had normal results. Out of the 11 abnormal MRA Brain majority had Infarction 10 [90.9%] and only one [9.1%] was a case of aneurysm. On MRA it was detected that most common artery involved was vertebral in 7 [63.6%] cases and one case [9.1%] each of basilar artery and PCA aneurysm was detected. However 2 [18.2%] cases revealed normal MRA. Four cases [36.4%] revealed no flow in MRA, 2 [18.2%] had stenosis, 1 [9.1] case each of AVM, dissection and hypoplastic artery were detected. However 2 [18.2%] cases had normal MRA. Conclusion- Patients with isolated vertigo due to Cerebellar infarction pose a significant diagnostic challenge to the emergency physician. So MR angiography is an important diagnostic tool for prompt confirmation of posterior circulation abnormalities. Keywords: Vertigo , [Mr Angio Or Mra] Magnetic Resonance Angiography. 1.
