Mixed attenuation mass in the pineal region extending to the third ventricle with peripheral foci of calcification. It appears to involve the origin of the aqueduct and effaces the right tectal plate.
Associated dilatation of the lateral and third ventricles consistent with obstructive hydrocephalus.
Fourth ventricle is normal in size. Minor sulcal effacement superiorly with loss of the extra-axial spaces in keeping with raised intracranial pressure.
No midline shift or cerebellar tonsillar herniation.
