Summary:

Description
  • Radiopaedia case ID: 85801
  • Image ID: 54202518
  • Image stack position: 38/82
  • Plane projection: Coronal
  • Aux modality: non-contrast
  • Study description: Three weeks earlier exam
  • Study findings: Striking difference when compared to available prior CT: cortical veins run adjacent to the inner table of the skull in the absence of hygroma.
  • Modality: CT
  • System: Central Nervous System
  • Findings: Advanced fronto-parietal dominant brain atrophy and chronic small vessel ischemic changes. Note lateral ventricle asymmetry. Thin, crescentic bilateral frontal subdural collections isodense to liquor. The cortical vein sign proves to be invaluable in outlining the boundary between the dilated subarachnoid space and the low density collections, and enables confident diganosis of bilateral subdural hygroma without iv. contrast in a patient with poor renal function.
