A neonate born at 38 weeks’ gestation by caesarean section for failure to progress was noted to have increased head circumference at birth and cranial US showed significant hydrocephalus. Contrast-enhanced MRI at 4 days of age revealed an avidly enhancing mass in the right cerebellopontine angle (Fig. 1). MR spectroscopy centred on the mass demonstrated a single choline peak at 3.2 ppm (Fig. 2). Histology of the resected mass after embolization showed it to be a choroid plexus papilloma.
