24 years Female (DOB:12/23/1991)Reason: hx hydrocephalus. VPS removed. Eval for vent sizes History: headachesPROVIDER/ATTENDING NAME: DAVID M. FRIM DAVID M. FRIM There is asymmetry in the size of the lateral ventricles with the left being slightly larger than the right but unchanged compared to prior exam. The septum pellucidum is bowed towards the right side. There is redemonstration of T2 and FLAIR signal hyperintense tracts along the right parietal lobe and left frontal lobe.The patient is status post burr hole placement adjacent to the left coronal suture. The patient is status post burr hole along the right parietal bone. A ventriculostomy tube is not currently identified.No abnormal 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 vein of Galen appears small as does the straight sinus. There is obtained of the venous structures at the region of the vena Galen. The middle cerebral artery vasculature also appears tortuous at the sylvian fissures.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.The cerebellar tonsils extend approximate 5 mm below the level of the foramen magnum.
1.The patient is status post previous ventriculostomy tube placement. There is no ventriculomegaly at this time.2.Low-lying cerebellar tonsils.3.Tortuous intracranial vasculature is a nonspecific finding.
