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

Renal cell carcinoma is known for its predilection for the posterior fossa in metastatic brain lesions. Key diagnostic features include hypervascular lesions on imaging, often with prominent enhancement. Clinically, these lesions can mimic primary cerebellar tumors or other vascular lesions, making accurate diagnosis crucial. Recognizing this pattern helps differentiate it from more common supratentorial metastases.
