Anatomy of the Brain: Ventricles

Anatomy 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...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Cerebral Edema ll: Pathophysiology

Cerebral 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...

Brain Abscess l: Introduction

Brain 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,...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary

This summary is machine-generated.

Dorsal third ventricular cysts, distinct from holoprosencephaly, show good outcomes with fluid diversion and shunting. This treatment effectively decompresses the cyst and stabilizes head circumference in pediatric patients.

Background:

Dorsal third ventricular cysts (DTVCs) associated with agenesis of the corpus callosum (ACC) are distinct from alobar holoprosencephaly (HPE) cysts.
Previous work established DTVC/ACC as a separate entity developmentally, radiologically, and clinically.

Purpose of the Study:

To describe the long-term outcomes of seven patients with DTVC treated with fluid diversion and shunting.
To clarify diagnostic discrepancies between DTVC and HPE dorsal cysts.

Main Methods:

Retrospective review of seven patients with DTVC undergoing fluid diversion and shunting.
Literature review to address diagnostic challenges in differentiating DTVC and HPE.

Main Results:

Postoperative imaging confirmed cyst decompression and head circumference stabilization.
Most patients (5/7) had no shunt revisions after initial placement.
Two patients required revision surgery due to delayed shunt malfunction.

Conclusions:

Fluid diversion and shunting demonstrate favorable clinical outcomes for DTVC.
This intervention is recommended for pediatric patients with DTVC, given its better prognosis compared to HPE.
