Variations of V3 and V4 segments of Vertebral Artery (VA) are very rare. We report an extremely rare case of hypoplastic and duplicated V4 segment of right VA along with variant origin of right Anterior Inferior Cerebellar artery (AICA) from right Posterior Inferior Cerebellar artery (PICA). AICA was duplicated. with one vessel arising from PICA and another arising from distal HVA. https://dmtcpptfr909.nizarblog.com/35080202/influence-of-urban-microclimate-on-air-conditioning-energy-needs-and-indoor-thermal-comfort-in-houses
