Ultrasound of preterm infant with bilateral grade 3 (extensive) cerebellar hemorrhage

Preterm infant with intrauterine growth restriction (28 weeks gestational age, 800 g birth weight) with grade 3 cerebellar hemorrhage (CBH). Coronal anterior fontanel view (A) shows mild ventricular dilatation (asterisk) and a suspected area of echogenicity within the posterior fossa (arrow) with asymmetric elevation of the tentorium on the left side (arrowhead). Midsagittal view (B) with increased echogenicity and loss of demarcation of the midline posterior fossa structures (dashed arrow). Right (C) and left (D) mastoid fontanel coronal views showing massive CBH of the complete left cerebellar hemisphere, also involving the vermis and central part of right cerebellar hemisphere (short arrow, thick arrow).
