Which type of metastatic brain lesion is most commonly found in the posterior fossa, despite the majority of metastases being supratentorial?

Renal cell carcinoma is known for its predilection for the posterior fossa. Key diagnostic features include hypervascular lesions on imaging, often with prominent enhancement after contrast administration. Clinically, these lesions may mimic primary cerebellar tumors or other metastatic lesions like melanoma. It's crucial to differentiate these as they can cause obstructive hydrocephalus due to their location.
