Aim: To analyse the epidemiology of posterior fossa tumors in paediatric age group. Material and Methods: The present study was conducted in the department of neurosurgery, among all the diagnosed cases of posterior fossa tumours attending and being admitted and treated to our institute during the study period were included in the study. During the study period, 480 cases of CNS tumours were reported, out of which 336 and 144 were supratentorialand infratentorial respectively. Results: Incidence of posterior fossa tumors (<12 Years) was reported among 96 subjects (20%), out of which 50 subjects were recruited for the present study according to the inclusion and exclusion criteria. Medulloblastoma, ependymoma, JPA and glioma was diagnosed among 48%, 24%, 20% and 8% of the subjects respectively. Complications viz. hydrocephalus, postoperative mutism, cerebrospinal fluid leaks, wound infection, cerebellar hematoma and CN palsies was found among 12%, 12%, 10%, 8%, 4% and 4% of the subjects respectively in our study. Mortality was reported among 8% (4) of the subjects. Conclusion: Early diagnosis of posterior fossa tumours is vital to prevent potential risks of Brain stem compression, herniation, hydrocephalus and death. With rapid advancement in radiology and advent of modern therapeutic modalities, early diagnosis and treatment reduced the morbidity and mortality rate and improved prognosis among the patients.
