Clinically normal newborn; caesarean section delivery, therefore risk screening of the brain.  

The germinal matrix proliferates at a maximum between the 24th and 32nd week of pregnancy, and is located at the walls of the lateral ventricles, behind the foramen of monroi and lateral to the choroid plexus between the caudate nucleus and thalamus.

The vessels are lined with a one-layered endothelium and are particularly vunerable to hypoxic-ischemic insults (high metabolism, large mitochondrial numbers) as well as to blood pressure changes.

The initially resulting subependymal hemorrhage can rupture into the ventricle, and is, depending on the amount of blood in the lateral ventricle, categorized as either a hemorrhage II° (<50% filled) or a hemorrhage III° (> 50% filled).

Ultrasound 1: Sagittal right: In the anterior horn area (in both lateral ventricles), one large cystic structure which is separated septally. The cystic changes were able to be seen on both sides on the 2nd day after birth, and reaches ventrally to the Foramen of Monroi. They did not change throughout the course of observation.

Ultrasound 2: Coronal: In the anterior horn area (in both lateral ventricles), one large cystic structure which is separated septally. The cystic changes were able to be seen on both sides on the 2nd day after birth.

Findings after brain hemorrhage of the first degree.  

Persisting cystic structure. If there is no disturbance in CSF circulation, the former coagulum has no clinical relavence.
