Germinal matrix hemorrhage - grade 3

Case contributed by Frank Gaillard
Diagnosis certain
ultrasound

Sagittal transcranial ultrasound demonstrates echogenic material in the ventricles and at the caudothalamic groove consistent with grade 3 subependymal hemorrhage. 

Sagittal and axial CT images demonstrate blood in the ventricles and at the left caudothalamic groove consistent with grade 3 subependymal hemorrhage. 

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

Case Discussion

Grading of germinal matrix hemorrhage is simple and prognostically important:

  • grade I
    • restricted to subependymal region
  • grade II
    • extension into normal-sized ventricles
  • grade III
    • extension into dilated ventricles
  • grade IV
    • same as grade III but with parenchymal hemorrhage
