Giant renal

schwannoma with obvious hemorrhage and cystic degeneration: a case report and literature review. MR findings of renal schwannoma. a Precontrast T1-weighted MR shows a slightly hyperintense mass (white arrow) arises from the kidney. T2-weighted axial (b) and cronal (c) plane MR shows the high-low mixed signal intensity mass (white arrow) with hydronephrosis (red arrow). No obvious enhancement (white arrow) on enhanced T1-weighted imaging (d)
