FIG. 46.18 Choroid Plexus Papilloma in 6-Week-Old Infant. (A) Angled sagittal and (B) coronal color amplitude (power) Doppler images show
increased tumor vascularity within the echogenic mass, with arterial supply arising from a branch of the basilar artery (arrow).
FIG. 46.19 Subdural and Subarachnoid Effusions From Meningitis. Magniied sagittal and coronal color Doppler images of interhemispheric
issure. Large bilateral partially hypoechogenic, partially hyperechogenic subdural and subarachnoid effusions. Supericial cortical vessels cross the
subarachnoid and subdural space to drain into the superior sagittal sinus. The ventricles are mildly dilated; the leptomeninges are thickened and
hyperechogenic.

FIG. 46.20 Lenticulostriate Vasculopathy. (A) Gray-scale sagittal sonography shows moderately hyperechogenic linear lesions within the
basal ganglia that prove to be prominent lenticulostriate vessels on color low Doppler sonography (B).
