Summary
Intraparenchymal diverticula, cavities within the brain, can develop in patients with chronic obstructive hydrocephalus. Further research is needed to understand their causes and best treatment approaches.
Area of Science:
- Neurology
- Radiology
- Neurosurgery
Background:
- Chronic obstructive hydrocephalus can lead to intraparenchymal cavities communicating with ventricles.
- The characteristics, development, and clinical significance of these intraparenchymal diverticula are not well-understood.
Purpose of the Study:
- To investigate the prevalence, features, and evolution of intraparenchymal diverticula in patients with chronic obstructive hydrocephalus.
- To explore potential associations between intraparenchymal diverticula and hydrocephalus severity or treatment.
Main Methods:
- Analysis of brain MRIs from 130 patients with chronic obstructive hydrocephalus.
- Exclusion of other causes of parenchymal cavities and evaluation of prior imaging for patients with diverticula.
- Recording of hydrocephalus parameters, including ventricle size and septum pellucidum integrity.
Main Results:
- 11 intraparenchymal diverticula were identified in 8 patients (6.2%), predominantly in males and older individuals.
- Diverticula showed a trend of association with hydrocephalus severity and some progressed over time.
- One case demonstrated cortico-spinal tract involvement and improved after ventricular shunting.
Conclusions:
- Intraparenchymal diverticulation is a potential finding in chronic obstructive hydrocephalus that clinicians should recognize.
- Further studies are necessary to elucidate the pathogenesis and optimal management strategies for these diverticula.

11.2K
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.

732
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...

01:20Mitral Regurgitation I: Introduction
1.1K
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...
