Tarlov Cyst synonyms

A Tarlov cyst, also known as a perineural cyst, is a fluid-filled sac that forms on the nerve roots at the base of the spine. These cysts are typically located in the sacral region of the spine, which is the lower back area. Tarlov cysts are named after Isadore M. Tarlov, the neurologist who first described them in the 1930s.

Tarlov cysts are often asymptomatic and are discovered incidentally during imaging tests for other conditions. However, in some cases, they can cause symptoms and lead to chronic pain and neurological problems. The exact cause of Tarlov cysts is not fully understood, but it is believed that they may develop due to a weakness in the protective covering of the nerve roots.

There are several synonyms for Tarlov cysts that are commonly used in medical literature. These include:

• Perineural cysts: This term is often used interchangeably with Tarlov cysts. It refers to the location of the cysts around the nerves.


• Sacral nerve root cysts: This term specifically describes the location of the cysts in the sacral region of the spine.


• Spinal meningeal cysts: This term emphasizes the association of the cysts with the meninges, which are the protective membranes surrounding the spinal cord and nerve roots.


• Arachnoid cysts: This term refers to cysts that develop within the arachnoid membrane, one of the layers of the meninges.

It is important to note that while these terms are used interchangeably, they all refer to the same condition of Tarlov cysts. The choice of terminology may vary depending on the medical professional or the specific context in which the condition is being discussed.
