Summary:

Description
  • Radiopaedia case ID: 37212
  • Image ID: 13180760
  • Image stack position: 20/64
  • Plane projection: Axial
  • Aux modality: CSF Flow
  • Modality: MRI
  • System: Central Nervous System
  • Findings: The lateral and third ventricles are moderately dilated and the fourth ventricle appears at least slightly enlarged. The temporal horns are dilated and the floor of the third ventricle is bowed inferiorly. The aqueduct is markedly dilated throughout its length but appears focally stenosed at its termination at its junction with the fourth ventricle. Flow studies suggests little if any cerebrospinal fluid flow passing through the aqueduct and T2-weighted scans show no evidence of pulsatility (no flow void) within the third and fourth ventricles, normally expected in communicating / normal pressure hydrocephalus. Empty sella noted. Corpus callosum is stretched and thinned, but no evidence of interstitial (transependymal) edema. Cortical sulci moderately flattened. Conclusion: Features are those of a long standing aqueduct stenosis.
