Which finding on cranial ultrasound in a preterm neonate defines grade III intraventricular hemorrhage?

• A Germinal matrix hemorrhage without ventricular extension
• B Intraventricular hemorrhage with ventricular dilation ✓
• C Intraventricular hemorrhage with periventricular echodensity
• D Intraventricular hemorrhage occupying more than 50% of ventricular volume

Explanation

The Papile classification grades intraventricular hemorrhage as: grade I, germinal matrix only; grade II, intraventricular hemorrhage filling 10 to 50 percent; grade III, intraventricular hemorrhage with ventricular enlargement; grade IV, parenchymal involvement. Periventricular echodensity suggests venous infarction, which belongs to grade IV, not grade III.
