36-year-old male with headache and weakness. This exam is limited secondary to artifact from the ventriculoperitoneal shunt system. The shunt enters through a right parietal burr hole, courses through the right parietal lobe and enters the atrium of the right lateral ventricle. It then crosses midline and terminates in the left lateral body of the left lateral ventricle. Hardware is also visualized overlying the sagittal suture anteriorly. The lateral ventricles appear prominent in comparison to the third and fourth ventricles, however without prior imaging one cannot determine if this is a acute finding or chronic in this patient. Further, there is no obvious pathology within the cerebral aqueduct or fourth ventricle. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect.No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. There is a retained mucous cyst within the left sphenoid sinus. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No evidence of intracranial hemorrhage, mass, or acute infarct.2. The lateral ventricles appear prominent compared to the third and fourth ventricles. However, there is no obvious pathology within the cerebral aqueduct or fourth ventricle. Comparison with prior imaging is recommended to determine if this is an acute finding.
