Case #39

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
