- Posterior cranial fossa tumours are often linked to paediatric cases but remain a significant proportion of adult intracranial neoplasms, with high risk due to the confined space.
- The region contains critical structures (cerebellum, brainstem, ventricular system, vascular elements), making even small lesions potentially serious.
- Common tumours include ependymomas, haemangioblastomas, metastases, pilocytic astrocytomas, cavernomas, and epidermoid cysts, each with distinct MRI features.
- Overlapping imaging characteristics and mass effect complicate diagnosis, highlighting the need for specialised imaging techniques such as DWI, GRE/SWI, MR spectroscopy, and contrast-enhanced studies.
- Accurate characterisation guides treatment options, prognosis, and surgical planning ensuring optimal patient management.
