What is the medical term for brain swelling?

The term "hydrocephaly" refers to an accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain, which can lead to increased intracranial pressure and brain swelling. This condition is often associated with various neurological issues and may require medical intervention. It is essential in the context of understanding brain conditions because inflammation and fluid buildup can significantly impact brain function and overall health.

Understanding this term is critical for identifying conditions that could lead to brain pressure and potential symptoms that might necessitate further examination or treatment in a clinical setting. The other options provided relate to fluid collections or conditions in different parts of the body and do not pertain to brain swelling directly.
