FIG 2. Surgically induced, increased enhancement of the choroid plexus. Note that the ventricle has been opened. Intraoperative T1-weighted images (left, 5 minutes postcontrast; middle, 20 minutes postcontrast) (532/15/3) show increased enhancement of the left choroid plexus (arrows) that remains constant during the observed time interval. Early postoperative MR image (right) (674/20/2) shows the persistence of this enhancement (arrow).
