Diagnosis: Benign intracranial hypertensionClinical question: eval VP shunt positionSigns and Symptoms: HA The CSF spaces are appropriate for the patient's stated age with no midline shift. The right lateral ventricle is smaller than the left lateral ventricle.The pontomedullary junction is present. The cerebellar tonsils are low lying. There is no evidence for pachymeningeal thickening or subdural effusions.There is a ventricular catheter was coarse of the right frontal lobe into the right lateral ventricle, through the third ventricle and into the posterior fossa abutting the basilar artery with tip in the posterior fossa anterior to the vertebrobasilar junction. There is metallic artifact present adjacent to the right frontal bone which obscures visualization superior and medial aspect of the right frontal lobe.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 demonstrate a minor opacity in the right ethmoid air cells. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Status post ventriculostomy tube placement as described above abutting the basilar artery with tip anterior to the vertebrobasilar junction.
