| Popis: | Choroid plexus papillomas are pliable, slow growing, pedunculated tumors arising from a vascular stalk that remains attached to the normal choroid plexus. This vascular pedicle allows these tumors to move freely within the ventricle, occasionally extending into and through the ventricular outlets. Although the occasional interventricular extension of a choroid plexus papilloma through the foramen of Monro, cerebral aqueduct, or foramen of Luschka or Magendie has been well documented in the pathology literature, its demonstration by CT or sonography has been described only twice. We present four cases of choroid plexus papilloma extending through the foramen of Monro. All four patients were evaluated by contrast enhanced CT and two by neurosonography. No other intraventricular tumor commonly extends through this ventricular outlet. The radiographic demonstration of the extension of an intraventricular mass through the foramen of Monro, cerebral aqueduct or foramen of Luschka or Magendie represents an anxillary diagnostic sign of choroid plexus papilloma.
