Pseudomeningocele

Pseudomeningocele

Pseudomeningocele (pronounced soo-doh-men-in-go-seel) is a medical condition that involves the formation of a cerebrospinal fluid-filled sac, typically resulting from a leak in the dura mater following a surgical procedure or trauma.

Etymology

The term "Pseudomeningocele" is derived from the Greek words "pseudo", meaning false, "meninx", meaning membrane, and "kele", meaning hernia or protrusion. Thus, it refers to a false protrusion or hernia of the meninges, the membranes that surround the brain and spinal cord.

Definition

A Pseudomeningocele is a collection of cerebrospinal fluid (CSF) that has leaked out of the dura mater and collected in a sac outside the dura. Unlike a true meningocele, which is a congenital condition, a pseudomeningocele is usually the result of a surgical procedure or trauma.

Symptoms

Symptoms of a pseudomeningocele can vary depending on its size and location, but may include headache, nausea, vomiting, and changes in vision or hearing. In some cases, a pseudomeningocele may not cause any symptoms and may only be discovered during an imaging study for another condition.

Diagnosis

Diagnosis of a pseudomeningocele typically involves imaging studies such as MRI or CT scan. These can show the presence of a fluid-filled sac outside the dura mater.

Treatment

Treatment for a pseudomeningocele may involve conservative measures such as bed rest and hydration, or surgical intervention to repair the dural leak. The choice of treatment depends on the size of the pseudomeningocele, the patient's symptoms, and the underlying cause of the dural leak.
