Aqueductal stenosis

Aqueductal Stenosis

Aqueductal stenosis (pronounced: ah-kwe-DUK-tal steh-NO-sis) is a neurological disorder that occurs when the aqueduct of Sylvius, a small canal that connects the third and fourth ventricles in the brain, becomes narrowed or blocked.

Etymology

The term "aqueductal stenosis" is derived from the Latin words "aqueductus" meaning "canal" and "stenosis" meaning "narrowing".

Causes

Aqueductal stenosis can be caused by various factors such as congenital defects, inflammation, tumors, or scar tissue. Congenital aqueductal stenosis is present at birth and is often associated with other developmental anomalies of the brain. Acquired aqueductal stenosis can occur at any age and is usually the result of a brain injury or disease.

Symptoms

Symptoms of aqueductal stenosis can vary depending on the age of the individual and the severity of the condition. Common symptoms include headaches, nausea, vomiting, balance problems, and vision disturbances. In severe cases, it can lead to hydrocephalus, a condition characterized by an excessive accumulation of cerebrospinal fluid in the brain.

Diagnosis

Diagnosis of aqueductal stenosis is typically made through neuroimaging techniques such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. These imaging studies can reveal the presence of a narrowed or blocked aqueduct of Sylvius.

Treatment

Treatment for aqueductal stenosis primarily involves managing the symptoms and preventing further complications. This may include medications to control symptoms such as headaches and nausea, and in some cases, surgical procedures may be necessary to relieve the blockage or to divert the excess cerebrospinal fluid.
