Findings
CT with contrast
- Mildly hyperattenuating mass in the body of the right lateral ventricle with cystic components along its medial margin and broad contact with the septum pellucidum
- Patchy internal areas of enhancement
MRI
- Heterogeneous mass in the body of the right lateral ventricle measuring 3.8 x 3.4 x 3.8 cm with a solid component laterally and multiple cystic components medially, broadly contacting the septum pellucidum
- The solid component is isointense on T2, mildly hyperintense on FLAIR, and demonstrates diffuse restricted diffusion and mild patchy enhancement
- Associated right lateral deviation of the septum pellucidum and mass effect on the third ventricle with resultant obstructive hydrocephalus involving the lateral ventricles and anterior aspect of the third ventricle
