A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas.
What is a cystic hygroma? A cystic hygroma is a fluid-filled sac (cyst) that forms most often on your baby’s neck due to a malformation or blockage of the lymphatic system.
Subdural hygroma is a medical condition characterized by the accumulation of cerebrospinal fluid in the subdural space of the brain. It can result from head trauma or develop spontaneously. Imaging techniques, such as CT scans and MRIs, are vital for diagnosing and assessing the condition.

A hygroma is a general medical term for a swelling or sac filled with fluid, often developing beneath the skin or in soft tissues. The word itself comes from the Greek term for “water-containing tumor,” although a hygroma is not cancerous.
What Is a Cystic Hygroma? A cystic hygroma is a rare type of cyst that babies can get, usually in their head or neck, if their lymphatic system gets blocked while it’s growing.
Small or asymptomatic subdural hygromas should be managed conservatively while addressing any underlying cerebrospinal fluid (CSF) leak, while symptomatic hy...
Subdural hygromas are an accumulation of CSF in the subdural space, likely due to separation of the dura and arachnoid. These are typically hypodense (CSF density) collections. These can remain stable or change in size over time and may exert mass effect on the parenchyma.
