Choroid plexus papilloma: detection by real-time and Doppler sonography.

Brain tumors arising in the neonatal period are rare and diagnosis is usually delayed. We encountered a case of choroid plexus papilloma (CPP) in a term newborn infant. The sonographic findings of this case demonstrated a striking similarity to intraventricular hemorrhage, an entity commonly seen in premature infants. A preoperative diagnosis was made, however, with the application of the pulsed Doppler technique showing markedly increased vascularity of this tumor. A search of the literature revealed only two reported cases of CPP demonstrated by sonography. The sonographic features of this rare tumor are reviewed . The potential role of Doppler sonography in the differential diagnosis of an intracranial ma s is discussed.
