Subdural hygromas (GSS) are a type of neoplasm that develops in the subdural space, i.e. space between the dura mater and the surface of the brain. Hygroma is considered the most common type of neoplasm in this space. Like most neoplastic lesions, GSS are incidental findings on MRI.
Hygromas are very rarely cancerous and cannot spread to other tissues or organs in the body. However, they require treatment as they can put pressure on surrounding brain structures, causing severe headaches, seizures and other symptoms. GSS can also lead to the development of memory problems, deterioration of mental abilities and even complete memory loss.
To treat hygroma, a surgical intervention is performed in which all possible tumors are removed and then the hygroma itself is removed. In some cases, it is possible to use radiation therapy, especially if the hygromas are located near important brain structures and are difficult to access for surgery. After surgery, it is important to rehabilitate with physical therapy and other treatments to minimize the risk of future recurrences.
It is worth noting that hygromas come in different types and sizes, and their precise treatment must be carried out individually for each patient. Moreover, some doctors believe that it is best to begin treatment for hygroma before symptoms appear in order to avoid their possible negative consequences.
No one can still explain the frequency of hygromas and their causes.
