FIG 1. A 70-year-old man with intraventricular cysts in both lateral ventricles. The cyst walls (arrows) are clearly depicted on this 3D-CISS image.
FIG 2. A 28-year-old man with central neurocytoma. Many small cystic components (arrows) are clearly visible within the tumor on this 3D-CISS image.
FIG 3. A 51-year-old man with ependymoma of the fourth ventricle. A 3D-CISS sequence clearly shows the relationship between the tumor and adjacent structures (arrows), making determination of tumor origin easy.
FIG 4. A 25-year-old man with anaplastic astrocytoma. A 3D-CISS sequence depicts multiple dissemination (arrows) in the ventricles.
