Abstract

Background: Tumors in the Posterior cranial fossa are well known for their critical location and complications like brain stem compression and hydrocephalus. This study was conducted to analyze the histological types, frequency of the posterior cranial fossa tumors in children at SMS medical collage Jaipur, Rajasthan.

Aims and Objectives: To find incidence and histomorphological pattern of posterior cranial fossa lesion in children; at our tertiary care center.

Material and Methods: It was a retrospective study in which 66 consecutive cases of posterior cranial fossa tumors in children are studies from January 2017 to May 2019.

Results: Among 66 cases,42 male and 24 female patients with male predominance.The morphological distribution of posterior cranial fossa lesion was as follows:- 25 cases Medulloblastoma, 21Pilocytic astrocytoma, 3 cases of each ependymomas and Epidermoid cyst, 2 cases of each Meningioma, Glioblastoma WHO grade 4 and abscess each,  1 case of eachSchwannoma,A-V malformation, arachnoid cyst,choroid plexus papilloma, TB,  ependymal cyst, AT/RT and colloid cyst.

Conclusion: Medulloblastoma and pilocytic astrocytoma are commonesttumor in pediatric age group with male predominance.

Keywords: Posterior cranial fossa, pediatric, medulloblastoma, pilocytic astrocytoma.
