Atypical teratoid/rhabdoid tumor
Primitive neuroectodermal tumor
Choroid plexus carcinoma
Fig. 110.1: (A) Sagittal T1WI showed a large, subcortical, solid-cystic mass in the left frontal lobe that is iso- to hypointense. (B–C) Axial DW MR images showed restricted diffusion in the solid component of the mass. Fig. 110.2: (A–B) Axial T2W images demonstrated a large frontal mass, with low signal on T2. Fig. 110.3: (A–B) Axial FLAIR images showed a moderately hyperintense tumor with central areas of high signal intensity due to necrosis. Fig. 110.4: Axial GRE-T2* WI sequence showed hypointense areas in the solid component representing hemorrhage or calcifications. Fig. 110.5: (A) Axial T1W and (B) Sagittal T1W postgadolinium images demonstrated a moderate enhancement of the tumor with non-enhancing areas of necrosis.
