Retrocerebellar Cyst

What is a Retrocerebellar Cyst?

A Retrocerebellar cyst also known as retroserebellyarnoy is a benign liquid formation. It may appear in variable sizes located in between the brain tissues. It forms at different locations in the brain due to the accumulation of fluid in areas where there was the destruction of the gray matter.


The most common reasons for the development of retrocerebellar cyst are:

  • Traumatic injuries (death of specific brain cells, concussion, bruises)
  • Stroke
  • Lack of blood flow to the brain
  • All kinds of infectious and inflammatory disease (meningoetsefalit, meningitis, etc.)
  • Surgical treatment of the skull
  • Dead regions of gray matter

Increase in the retroserebellyarnoy can cause ongoing infectious process, neuro-infection, chronic circulatory disorder, multiple sclerosis or an autoimmune process in the brain.


The symptoms directly depend on the size, location and causes of occurrence of the cyst. If the cyst increases in size, it can develop multiple symptoms like:

  • Partial or complete paralysis of the cyst
  • Difficulty in vision
  • Sudden loss of consciousness
  • Headache
  • High blood pressure and feeling of fullness in the head
  • Temporary or permanent body numbness
  • Temporary hearing loss, tinnitus
  • Throbbing inside the skull


  • CT Scan
  • MRI
  • Ultrasonography


Before any treatment, a person may pass through few clinical examinations to determine the reasons behind the cyst. The treatment primarily aims at discharging the elements that can affect the growth of the cyst. The therapy also takes care of inhibition of inflammation and recovery of damaged brain cells. If the cyst is already large, then it requires surgical intervention.
