FIG 6. Colloid cyst imaged using FLAIR images (different patient).

A, Axial T2-weighted image shows small, rounded, hypointense colloid cyst (arrow) in the anterior aspect of the third ventricle.

B, FLAIR image obtained at nearly the same level shows that the colloid cyst (arrow) appears slightly larger than on A and is indistinguishable from the surrounding CSF.
