The most common anomalies of cranio-vertebral junction are Chiari malformations. Chiari malformations constitute a variety of four main syndromes (I, II, III, and IV), which describe the protrusion of brain tissue into the spinal canal through the foramen magnum. These malformations frequently occur in combination with other pathological entities such as myelomeningocele, hydrocephalus, and/or hydrosyringomyelia.They involve both skeletal and neural structures. The incidence of Chiari Malformation was 1 in 1000 births but with the increased use of imaging techniques such as CT scans and MR imaging it is suggested that this condition is much more common than thought earlier to be. However it is very difficult to estimate the exact rate of occurrence as some of cases are asymptomatic or do not develop symptoms till adulthood. In the present study 100 MRI films of patients with symptoms pertaining to chiari malformations from North Karnataka region were studied and interpreted.
