How Do You Spell EPENDYMAL CYST?

1. An ependymal cyst is a fluid-filled sac or cavity that develops within the ependymal lining of the central nervous system. Ependymal cells are specialized cells that line the ventricles and the spinal canal. They are responsible for producing cerebrospinal fluid (CSF), which surrounds and protects the brain and spinal cord. In some cases, due to developmental abnormalities or injury, these cells can trap fluid and form cysts.

   Ependymal cysts are typically benign and do not cause any symptoms. They are often discovered incidentally during imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. However, in some rare cases, larger or symptomatic ependymal cysts can lead to neurological problems.

   The exact cause of ependymal cysts is not fully understood. However, they are thought to develop as a result of a congenital malformation or an injury to the ependymal cells. It is important to differentiate ependymal cysts from other cystic lesions, such as arachnoid cysts or neuroepithelial cysts, as treatment approaches may vary.

   Treatment for ependymal cysts is typically only necessary if they cause symptoms or complications. For small, asymptomatic cysts, regular monitoring with imaging studies may be recommended. In cases where the cyst is causing significant symptoms or complications, surgical intervention may be necessary to remove or drain the cyst. The prognosis for individuals with ependymal cysts is generally good, with most patients experiencing resolution of symptoms following appropriate treatment.

2. A circumscribed distention of some portion of the central canal of the spinal cord or of the cerebral ventricles.

Common Misspellings for EPENDYMAL CYST

The word "ependymal" is derived from the Greek word "ependyma", which means "a garment" or "that which is thrown over". In anatomy, the term "ependyma" refers to a cellular lining found on the inner surface of certain structures within the brain and spinal cord, known as the ventricles and the central canal, respectively.

The word "cyst" has its roots in the Latin word "cystis", which originates from the Greek word "kystis". Both of these words mean "bladder" or "pouch". In medical terminology, a cyst is generally defined as a closed sac or cavity within the body that contains fluid, semi-solid material, or gas.

Therefore, when combining these terms, an "ependymal cyst" refers to a cystic structure that arises from the ependymal lining in the brain or spinal cord.
