Primitive neuroectodermal tumor (PNET). A, Axial T2-weighted image demonstrates a large hemispheric heterogeneous signal mass with areas of cyst formation (white arrow). Note iso-intense signal of the mass on T2-weighted image reflecting high cellularity. B, Axial Tl -weighted image demonstrates presence of hemorrhage (arrowhead). C, Axial postcontrast Tl -weighted images shows heterogeneous enhancement pattern. (Click to magnify figure)Monday, June 14, 2010
