Background: Chiari malformations are herniation of part of cerebellum into the foramen magnum. Professor Hans Chiari classified chiari malformations into four types: type I to type IV. Type I chiari malformation is the most extensively studied entity. Type III and IV are very rare variety.
Aim: Magnetic Resonance Imaging (MRI) study of the different types of chiari malformations in a tertiary care hospital in North-East India.
Materials and Methods: After performing MRI of brain and spinal cord, 63 cases of chiari malformations were included in the study. The cases were classified according to the classification of Hans Chiari.
Results: 73.02% cases were type I followed by 22.22% cases of type II chiari malformations. Male predominated female and more than half of the patients were under twenty years of age. Hydrocephalus and syringomyelia were mostly associated with type I chiari malformations. Conclusion: various aspects of such a rare type of congenital anomaly were studied in this part of the country.
Key words: Chiari malformations, MRI, Syringomyelia, Hydrocephalus.
