The first ultrasonographic diagnosis of PVPC in a neonate is attributed to Levene in 19807. Following this initial description, several series have been published1,3,5. Typically, pseudocysts are located in the caudothalamic groove or in the caudate nucleus, lateral to the. The identification of GM hemorrhage is made by the detection of increased echogenicity within the caudothalamic groove without intraventricular hemorrhage seen on ultrasound examination. There is a well defined evolution of germinal matrix hemorrhage seen in neonates with intraventricular hemorrhage and hydrocephalus and in some cases evolution. Unlike schizencephaly, porencephalic cysts are not lined by dysplastic gray matter. Periventricular pseudocysts (germinolytic cysts) occur at the caudothalamic groove in a variety of infectious, noninfectious, metabolic, and chromosomal abnormalities. Caudothalamic groove cysts can also be due to germinal matrix hemorrhage. 1
