Findings
CT
- Mixed cystic and solid suprasellar mass with internal coarse calcification
- Left frontal approach ventricular shunt catheter terminating in the frontal horn of the left lateral ventricle
- Asymmetric prominence of the frontal horn of the right lateral ventricle, which may represent differential shunting
MRI
- Mixed cystic and solid suprasellar mass measuring 3.5 x 2.3 x 4.2 cm with solid enhancement of the solid components and peripheral enhancement of the cystic components
- Intrinsic T1 signal hyperintensity within a few of the cystic components (particularly the most anterosuperior cyst), which may represent intralesional hemorrhage or proteinaceous debris
- The mass contacts and anteriorly displaces the optic chiasm and splays the optic tracts
- The pituitary gland is seen separate from the mass
