CT

• Mixed solid and cystic mass in the right frontal lobe with internal calcification and surrounding vasogenic edema
• The solid component is mildly hyperattenuating relative to brain parenchyma
• Resultant midline shift anteriorly and crowding of the frontal horns of the lateral ventricles

MRI

• Complex cystic and solid intra-axial mass in the right frontal lobe with the solid component measuring 4.5 x 2.6 x 4.3 cm and the cystic component measuring 4.5 x 3.6 x 3.9 cm
• The solid component diffusely enhances and demonstrates restricted diffusion
• The cystic component peripherally enhances
• Surrounding vasogenic edema
• Resultant midline shift anteriorly and crowding of the frontal horns of the lateral ventricles
• No evidence of downward transtentorial herniation or hydrocephalus
