FIG 9. False-positive finding on 3D-CISS image in an 11-year-old girl.

A and B, A small masslike nodule is seen at the fundus of the left internal auditory canal on 3D-CISS (16/8/1) image (arrow, A), although no mass is seen on 3D-FASE (5000/241.6/1) image (B). This artifact was assumed to be due to the combination of susceptibility and flow artifacts.
