Male, 16 years old, with a suprasellar cystic lesion status post fenestration, yearly follow-up exam. The left frontal approach ventricular catheter remains in stable position coursing inferiorly and medially through the left frontal horn, foramen of Monro, and third ventricle, traversing the ventriculocisternostomy to terminate within the cystic suprasellar space. This cystic space shows no significant interval change in size measuring 20 x 16 mm in the axial plane (image 12 series 601).The pituitary gland remains evident along the floor of the sella and is stable in size and morphology. No restricted diffusion, parenchymal signal abnormality, edema or new mass effect seen. No new abnormal extra-axial fluid collections are detected. The ventricular system is unchanged in size and configuration.
