Patients were followed up on medical treatment and their pain severity evaluated on their follow-up visit. Patients were divided into two groups based on prepontine cisternal space (Group A: \u22644 mm, Group B: >4 mm) and into three groups based on the percentage reduction of pain, Group 1 (0\u201335%), Group 2 (36\u201370%), and Group 3 consisted of patients with pain reduction of more than 70%. Ipsilateral prepontine cisternal space thickness was correlated with grade of NVC and percentage reduction of pain.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n Mean percentage of pain reduction in group A and group B was 34.12 and 60.68%, respectively. Approximately 23.80% of grade1 NVC were seen in group A and 76.20% in group B, while 80% of grade 3 NVC were seen in group A and only 20% were seen in group B.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n There was poor response to medical treatment, in patients with narrowed prepontine cisternal space thickness with an inverse relationship between the grade of NVC and
