What is colloid cyst of third ventricle?
A colloid cyst is a fluid-filled sac that forms in the brain, usually in the third ventricle. These spherical cysts have a smooth rind and are filled with a gelatinous material called colloid. Colloid can range from being very fluid to having a nearly solid core.
How serious is a colloid cyst?
These cysts are usually benign and may sit quietly in the brain for years, but they can eventually grow larger and cause neurological symptoms. Colloid cysts can obstruct the flow of cerebrospinal fluid, causing fluid buildup in the ventricles of the brain (hydrocephalus) and increased pressure within the skull.
Does a colloid cyst have to be removed?
Because a colloid cyst can obstruct the flow of fluid into the brain’s third ventricle, it requires immediate medical attention. Common symptoms of colloid cysts include memory problems, headaches, loss of consciousness, and confusion. Surgery to remove the colloid cyst generally cures a person with this condition.
How are colloid cysts removed?
Fortunately, most symptomatic or large colloid cysts can now be safely removed through a minimally invasive endoscopic technique or brain port technique via a quarter-sized bony opening in the skull. This procedure typically resolves the hydrocephalus and associated symptoms.
Can a colloid cyst cause a brain bleed?
Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly.
Can a colloid cyst burst?
Intraventricular rupture of a colloid cyst is a rare phenomenon and has been proposed as a mechanism for sudden death in patients with colloid cysts. Imaging of a colloid cyst during rupture has been described in only one other instance.
Can a colloid cyst cause fatigue?
When a colloid cyst is symptomatic, it most commonly causes non-communicating hydrocephalus. Symptoms of hydrocephalus can include headaches, nausea, vomiting, lethargy, coma, and death.
Can a colloid cyst grow back?
Some colloid cysts can be watched for years to decades without any issue. Others can slowly grow in size or cause subacute or acute hydrocephalus. With complete surgical resection, the prognosis is good, and colloid cysts are rare to recur after complete resection.
What does a colloid cyst headache feel like?
The headaches are described as intermittent, severe and intense, and of short duration and usually are located frontally. The main associated features are nausea and vomiting. The headache can be relieved by lying down, which is unusual for headaches secondary to intracranial tumors.
What is the function of the 3rd ventricle?
The third ventricle is one of the four ventricles in the brain that communicate with one another. As with the other ventricles of the brain, it is filled with cerebrospinal fluid, which helps to protect the brain from injury and transport nutrients and waste.
What causes a colloid cyst?
The cause of a colloid cyst is unknown, but it is believed to have its roots in fetal development. The rind (wall) of the cyst is a remnant of normal embryologic tissue. There is nothing known to cause a colloid cyst — it is not associated with exposure to radiation, cell phone use, or prenatal care.
What is the treatment for a cyst on the brain?
Treatment may simply require watching the cyst determine if it is growing or causing any problems. This is accomplished by successive brain scans. If the cyst is growing in an area that would cause a problem the physician may suggest surgery which typically involves draining the cyst and then surgically removing it.
What is a colloid brain cyst?
What is a Colloid Cyst? Colloid cysts are mucous-like masses that most commonly appear near the center of the brain, at the point where the lateral ventricles — two of the brain’s natural fluid chambers — drain into the third ventricle.
