Cerebral Atrophy

  • Etiology: hypoxic ischemic encephalopathy, ECMO
  • Imaging: diffuse prominence of the sulci and ventricular system

Cases of Cerebral Atrophy

CT of cerebral atrophy after being on extracorporeal membrane oxygenation (ECMO)
Axial CT without contrast of the brain shows diffuse prominence of the sulci and ventricular system.
CT of intraventricular hemorrhage, intracerebral hemorrhage, and cerebral atrophy in a patient on extracorporeal membrane oxygenation (ECMO)
Axial CT without contrast of the brain shows mixed-density fluid in the left lateral ventricle posteriorly and mixed-density fluid in the left parietal-occipital lobe. There is also diffuse prominence of the sulci and ventricular system.
MRI of acute and chronic subdural hematomas in child abuse
Axial CT without contrast of the brain (upper left) shows bilateral large low density extra-axial fluid collections and a left frontal small high density extra-axial fluid collection. There is also prominence of the cortical sulci and the ventricular system. Axial T1 (upper right), T2 (lower left) and FLAIR (lower right) MRI without contrast of the brain better demonstrates the extra-axial fluid collections with the bilateral large collections being bright on T1 and T2 and the small left frontal collection being iso on T1 and dark on T2.
