Ultrasound of preterm infant with bilateral cerebellar hemorrhage and subdural posterior hemorrhage

Cranial ultrasound using coronal mastoid fontanel view in a preterm infant (gestational age 26 weeks) with a complicated breech delivery, showing bilateral cerebellar hemorrhage (arrows) and subdural posterior hemorrhage (short arrows). Note that the subdural hemorrhage has a lower echogenicity than the cerebellar hemorrhage and has a mass effect on the cerebellar hemisphere.
