Female 69 years old; Reason: third ventriculostomy,suspected aqueductal stenosis History: 6 month follow up. No acute intracranial hemorrhage. No intra- or extra-axial fluid collections. Again seen is a recumbent AP paramedian frontal burr hole. Linear low attenuation traversing the right frontal lobe and terminating into the right lateral ventricle likely result of prior instrumentation. Punctate focus of air within the right frontal horn has resolved.Redemonstration of enlargement of the lateral and third ventricles, which are unchanged compared to previous exam. Periventricular low attenuation of white matter is similar to prior exam corresponding to regions of small vessel ischemic strokes on prior MRI study and are unchanged. Possibility of underlying periventricular exudate of CSF should also be considered.The visualized osseous structures and soft tissue extracranial components are without abnormalities.
1.No significant interval change in the size of the supratentorial enlarged ventricular system.
