28 year old female status post shunt internalization The intracranial catheter courses through right frontal lobe, enters the left lateral ventricle with tip terminating near the left anterior limb of the internal capsule. This catheter course is unchanged when compared to prior examination.The CSF spaces are appropriate for the patient's stated age with no midline shift or evidence of hydrocephalus.Low density change in the pons, bilateral temporal lobes, and left cerebellar folia are noted, but much better demonstrated on previous MRI.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.
Unchanged position of right frontal approach ventriculostomy and unchanged ventricular sizes without evidence of hydrocephalus.
