"When located in the posterior fossa in children (less common), other tumours to be considered include:"
"In adults, and depending on location, consider:"
"The tumours are usually well-defined lobulated masses, either iso- or somewhat hyperdense compared to the adjacent brain. There is associated hydrocephalus. They usually enhance homogeneously, demonstrating an irregular, frond-like pattern that results in a cauliflower-like appearance. If there is markedly heterogeneous contrast enhancement, a choroid plexus carcinoma should be suspected 4."
