Summary
Familial colloid cysts of the third ventricle are rare and can cause sudden death. Early brain CT scans are recommended for individuals with a family history presenting with headaches.
Area of Science:
- Neurology
- Neurosurgery
- Genetics
Background:
- Colloid cysts of the third ventricle are uncommon benign brain tumors.
- Familial occurrence of these cysts is exceptionally rare.
- These lesions can lead to obstructive hydrocephalus and increased intracranial pressure.
Observation:
- A 24-year-old pregnant woman with a known family history of colloid cysts presented with severe headaches.
- She experienced a sudden cardiorespiratory arrest, necessitating emergency intervention.
- The patient had a confirmed familial colloid cyst of the third ventricle.
Findings:
- The case highlights the potential for rapid neurological deterioration in familial colloid cysts.
- Surgical excision is a definitive treatment for symptomatic colloid cysts.
- Prompt diagnosis is crucial, especially in pregnant patients with concerning symptoms.
Implications:
- This case underscores the importance of considering familial colloid cysts in the differential diagnosis of headaches, particularly in those with a family history.
- Early neuroimaging, such as computed tomography (CT) scans, is vital for patients presenting with headaches and a relevant family history.
- Timely intervention can prevent catastrophic outcomes like cardiorespiratory arrest.

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:23Cystic Fibrosis: Pathogenesis
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

01:29Cardiomyopathy III: Hypertrophic Cardiomyopathy
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
