Reason: right CP angle enhancing masss History: compare to previous BRAINThe CSF spaces are appropriate for the patient's stated age with no midline shift. There is a small focus of encephalomalacia present along the inferior lateral aspect of the right cerebellar hemisphere. This is unchanged since the prior examThe patient is status post right suboccipital craniotomy.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.IACThere is a 19x 13 mm axial dimension mass at the right cerebellopontine angle cistern which previously measured 19x13 mm on 12/5/13. This mass abuts the right trigeminal nerve at its origin from the pons. The cochlea and semicircular canals appear intact. The cochlear nerve can be followed bilaterally tracking into the cochlea. The modiolus is well formed bilaterally.
