Where are Connatal cysts seen?
Connatal cysts are located at or just below the superolateral angles of the frontal horns or body of the lateral ventricles and are mainly anterior to the foramina of Monro (,Figs 8–,,,10,,,).
What is periventricular cyst?
Periventricular cysts are a common finding in neonatal cranial imaging. The differential diagnoses of supratentorial periventricular cysts are numerous, and include connatal cysts, subependymal cysts, porencephalic cysts and cystic periventricular leukomalacia (Figure 3).
What is an ependymal cyst?
Ependymal cysts are rare benign neuroepithelial cysts lined by ependymal cells. Most are small and asymptomatic and only cause symptoms if large. On imaging, these cysts are essentially indistinguishable from other intraventricular simple cysts (e.g. intraventricular arachnoid cysts).
What is Ependymitis Granularis?
Ependymitis granularis sounds far more worrying than it actually is. The term refers to a histological feature that contributes to symmetrical foci of periventricular high T2 and FLAIR signal hyperintensity anterior and lateral to the frontal horns.

What causes cysts in fetal brain?
A choroid plexus cyst happens when a small amount of the cerebrospinal fluid gets trapped in the layer of cells as your baby’s brain grows and develops. The cysts go away on their own during pregnancy, usually by week 32.
Can PVL be seen on ultrasound?
In a baby with PVL, the ultrasound shows cysts or hollow places in the brain tissue. Sometimes the condition can’t be seen with an ultrasound right away. So healthcare providers give babies at risk for PVL an ultrasound 4 to 8 weeks after birth.
How are epididymal cysts treated?
Epididymal cyst removal or excision is a procedure to remove these cysts from the scrotum. An alternative to open surgery is to drain the fluid with a needle under ultrasound guidance. Both procedures are effective in the short term, but the cysts are much more likely to come back after needle drainage.
What does white matter changes in the brain mean?
White matter disease is an umbrella term for damage to your brain’s white matter caused by reduced blood flow to the tissue. It can cause issues with memory, balance and mobility. People who have risk factors for cardiovascular disease also have a greater risk of developing white matter disease.
What is the meaning of Fazekas grade 1?
The modified Fazekas scale ranges from mild to severe. Mild WMH (grade 1) was defined by punctate lesions in the deep white matter with a maximum diameter of 9 mm for a single lesion and of 20 mm for grouped lesions.
How common is a cyst on the brain of a fetus?
As mentioned, choroid plexus cysts are present in 1 to 2 percent of normal fetuses. However, in a very small percentage of fetuses with choroid plexus cysts, there is an associated chromosome disorder called trisomy 18.
How common are brain cysts in babies?
A choroid plexus cyst is a build-up of fluid found in the choroid section of an unborn baby’s brain. It’s estimated that choroid plexus cysts happen in about 2% of pregnancies, usually during the second trimester.
