What is degenerative subcortical cyst?

A degenerative subcortical cyst is a fluid-filled sac that forms beneath the cerebral cortex, often associated with age-related changes or degeneration of brain tissue. These cysts can result from various factors, including ischemia or trauma, and may not necessarily cause symptoms. In some cases, they can be detected incidentally on imaging studies. Treatment may not be required if the cysts are asymptomatic, but monitoring is essential to assess any changes over time.
