FIG 4. Right CPA epidermoid tumor in a 48-year-old man.
A, On fast-FLAIR imaging (10002/148/1, inversion time of 2200), epidermoid tumor appears to extend over the midline in the prepontine cistern (arrow).
B, Echo-planar DW imaging (1600/126 with b value of 1000 s/mm2; field of view, 36 x 24 cm) reveals that the lesion (black arrow) is limited in the right CPA. Note the susceptibility artifacts near the temporal bone (white arrows).
C, ADC map shows that the tumor (arrow) has an ADC similar to that of surrounding brain tissue.
