What is a choroid plexus cyst on ultrasound?
Choroid plexus cysts are often found during an ultrasound. They occur when a small bubble of fluid breaks away as the choroid plexus forms. The cysts aren’t considered to be abnormal. Most choroid plexus cysts clear up without requiring further medical intervention.
What is Multicystic encephalomalacia?

What are porencephaly and schizencephaly?
The term porencephaly is often used interchangeably with porencephalic cyst, schizencephaly, cystic brain degeneration, and congenital brain clefts. Porencephaly was first described in 1859 as a cavity or cleft of the cerebral cortex ( Heschl, 1859 ). These lesions may or may not communicate with the ventricular and subarachnoid systems.
