Description
Medulloblastoma is a malignant embryonal neuroepithelial tumour, rarely occurring in adults. The 2021 WHO CNS classification subdivided medulloblastoma into 4 groups based on molecular data, which may correspond to morphological features on imaging which are useful to recognise. Differential diagnoses in adults include ependymoma, hemangioblastoma, metastases, lymphoma, and high-grade glioma.
We report the case of a double cerebellar medulloblastoma in a 34-year-old adult. We also highlight the differential diagnosis between medulloblastoma and other posterior cerebellar fossa tumours in adults providing practical elements to help suggest the most accurate diagnosis.
