A neonate born at 26 weeks gestation develops periventricular-intraventricular hemorrhage on cranial ultrasound. Grade III IVH is identified. Which of the following is the most accurate classification of Grade III IVH according to Papile?
- A Blood confined to the germinal matrix
- B IVH with ventricular dilatation ✓
- C IVH without ventricular dilatation
- D IVH with periventricular parenchymal hemorrhage
Correct answer: B. IVH with ventricular dilatation
Explanation
In the Papile classification: Grade I is subependymal/germinal matrix hemorrhage only; Grade II is IVH without ventricular dilatation (filling less than 50% of the ventricular volume); Grade III is IVH with ventricular dilatation (filling more than 50% of the ventricle, causing enlargement); Grade IV is IVH with periventricular parenchymal (intraparenchymal) hemorrhage (now often termed periventricular hemorrhagic infarction). Grade III carries significant neurodevelopmental morbidity, and Grade IV has the worst prognosis.
