Aqueductal stenosis

Aqueductal stenosis is a neurological disorder that occurs when the long, narrow passage (the aqueduct of Sylvius) that connects the third and fourth ventricles in the brain is narrowed or blocked. This can be due to congenital causes, inflammation, tumor, or scarring. This condition can lead to hydrocephalus, a buildup of cerebrospinal fluid in the brain.

Causes

Aqueductal stenosis can be caused by a variety of factors. It can be congenital, meaning it is present at birth. This is often due to a genetic mutation or abnormal development during pregnancy. It can also be acquired later in life due to inflammation, tumor, or scarring in the brain.

Symptoms

The symptoms of aqueductal stenosis can vary depending on the age of the individual and the severity of the condition. Common symptoms include headache, nausea, vomiting, lethargy, and balance problems. In severe cases, it can lead to coma or death.

Diagnosis

Aqueductal stenosis is typically diagnosed through imaging tests such as MRI or CT scan. These tests can show the narrowing or blockage in the aqueduct of Sylvius and the buildup of cerebrospinal fluid in the brain.

Treatment

The treatment for aqueductal stenosis typically involves surgery to relieve the buildup of cerebrospinal fluid. This can be done through a procedure called a ventriculostomy, which creates a new pathway for the fluid to flow. In some cases, a shunt may be placed to divert the fluid to another part of the body where it can be absorbed.
