  1. Ependymoma
  2. Choroid plexus carcinoma
  3. Central neurocytoma
  4. Subependymal giant cell astrocytoma
  5. Meningioma


Congratulations to those who guessed choroid plexus carcinoma.

These are rare, homogenously enhancing lesions, often associated with hydrocephalus. They are usually iso-intense on T1- & T2-weighted images. Mostly occur in children during the first 5 years of life.
