Abstract
Objective: The goal of this pictorial essay is to help the radiologist have a refined approach to formulating an appropriate differential diagnosis for paediatric and adult primary posterior fossa masses.
Materials and Methods: This pictorial essay will review posterior fossa masses in both adult and paediatric patients seen at our institution for the past 3 months. it was an observational cross sectional study. the sample size was 100. Those cases with symptoms related to posterior fossa such as vertigo, imbalance, nystagmus, difficulty in gait were included in the study. the study population included both adult(60 cases) and pediatric case(40 cases)
Results: We got a spectrum of cases of posterior fossa lesions .predominant lesions noted in the pediatric population were ependymoma and medulloblastoma. the adult cases that were encountered were acoustic schwannoma, epidermoid cyst, intraventricular meningioma, cysticglioma.
The posterior fossa masses are presented in 2 categories: paediatric, adult. Distinguishing MR imaging features and demographics are discussed for each mass, with select cases reviewing uncommon and atypical appearances.
Conclusion: Posterior fossa masses are a relatively common finding for radiologists. In some cases, it can be difficult to definitively diagnose these masses by using imaging findings alone.
However, posterior fossa masses often preferentially present in specific age groups and have characteristic MR imaging findings, which can either help formulate the correct diagnosis or significantly narrow the working differential diagnosis.
Keywords: posterior fossa mass, MRI, adult, children.
