To study embryology, anatomy and topographic relationship of craniovertebral junction on imaging. To understand imaging features of various craniovertebral junction abnomalies on CT and MRI

Craniovertebral Junction (CVJ) is a complex osseous-ligamentous structure responsible for enclosing the traversering neural elements as they make a transition from brain to spine. EMBRYOLOGY& ANATOMY:The CVJ is the product of the occipital and first three cervical somites with subsequent endchondral ossification.A myriad of congenital and aquired anomalies affect CVJ presenting with varying clinical symptoms. CVJ ANOMALIES :Congenital anomalies include basilar invagination, atlanto axial dislocation, platybasia,atlas defects( split Atlas ,posterior Rachiscisis),defect in synchondrosis of axis ( aplasia, Os odontoideum,os terminale). Acquired conditions include trauma,infections,inflamatory ( rheumatoid, JRA, CPPD, ankylosing spondylitis) and tumors. IMAGING:CT and MRI are used to asses craniometry,morphology and topographc relation of various constituents, pre dental soft tissue,cord status,ligamentous morphology,vetebral artery course and stablity of AAD CONCLUSION:CT and MRI charecterisation of CVJ anomalies is must for accurate diagnosis and management
