For Michelle Erickson, Medical 101 (aka: Swallow Your Pride Bitch)

Here's medical 101 for Michelle Erikson, who scoffed at my concern that there had been zero follow-up of my son's bilateral choroid cysts. Most of the time, they go away on their own, but every medical journal states follow-up is necessary to ensure this is true. Choroid cysts also must be distinguished from other forms of cysts that lead to damage in the brain. They can hemorrhage as well:

Chorioïd plexus cyst
In postnatal US these cysts of the chorioïd plexus are often incidental findings without clinical consequences.
Chorioïd plexus cysts (CPC) are however of importance for obstetricians.
At prenatal US these cysts can be predictive of trisomy 18.
About half of babies with Trisomy 18 show a CPC on ultrasound, but nearly all of these babies will also have other abnormalities on the ultrasound, especially in the heart, hand, and feet.


An exeption must be made for cysts that arise close to the foramen of Monro.
Although these cysts often disappear spontaneously, follow up US is necessary to ensure disappearance.
Some may produce symptoms of raised intracranial pressure due to obstruction to the cerebrospinal fluid (CSF) flow.
