History of traumatic brain injury and refractory epilepsy. Redemonstrated postsurgical changes from left frontal craniotomy. There is a left frontal ventriculostomy catheter with tip at the midline at the level of the foramen of Monro. There is gliosis related to a prior right frontal ventriculostomy catheter.Stable cystic encephalomalacia in the bilateral frontal lobes is not significantly changed from prior.The anterior horn of the left lateral ventricle remains decompressed. Moderate dilatation of the right lateral and third ventricles appears similar to prior. There is persistent midline shift to the left measuring 3 mm.The pituitary is stable in appearance and remains upper limits normal abutting the overlying optic chiasm and measuring 9 mm in craniocaudal dimension (previously 10 mm).The expected intracranial vascular flow voids are present.The paranasal sinuses are clear. The visualized mastoid air cells are clear. The orbits are unremarkable.
1. Stable posttraumatic findings including extensive cystic encephalomalacia involving the bilateral frontal lobes.2. Left frontal ventriculostomy catheter with stable ventriculomegaly of the right lateral ventricle and third ventricle.3. Stable appearance of the pituitary gland which is upper limits of normal in size.
