From: CT and MRI findings of intra-parenchymal and intra-ventricular schwannoma: a series of seven cases
MRI findings of a 12-year-old man with intraparenchymal schwannoma. A well-defined heterogeneous mass with peritumoral edema (arrow) and cystic degeneration (arrow head) is observed in the right frontal lobe (A and B). The mass shows hypo-intensity on T1 WI and hypo-/hyper-intensity on T2WI. The hypo-intensity area on T1WI and T2WI was suggestive of calcification (B). Heterogeneous, marked and delayed enhancement could be observed on the axial and coronal T1WI (C and D)
