Anatomy of the Brain: Ventricles

11.1K
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.

Cranial and Spinal Meninges

4.9K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Viral Meningitis01:18

Viral Meningitis

96
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

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...

Area of Science:

  • Neurosurgery
  • Oncology
  • Neuropathology

Background:

  • Third ventricular meningiomas (TVM) are rare intracranial neoplasms.
  • Limited literature exists on their clinical, radiological, pathological, and surgical characteristics.

Purpose of the Study:

  • To discuss the clinical, radiological, pathological, and surgical features of TVM.
  • To analyze patient follow-up and outcomes for these rare tumors.

Main Methods:

  • Retrospective review of 13 patients with TVM diagnosed between 2003-2013.
  • Analysis of clinical, radiological, pathological, and surgical data.
  • Statistical analysis of Karnofsky performance scale (KPS) scores.

Main Results:

  • TVM constituted 0.11% of all intracranial meningiomas.
  • Radiologically classified into anterior, posterior, and entire third ventricle types.
  • Total tumor removal achieved in 61.5% of patients; 15.6% were WHO Grade II.

Conclusions:

  • TVM require differentiation from other rare neoplasms like choroid plexus papilloma.
  • Surgery is the optimal treatment, leading to favorable prognoses.
  • Radiological subtype classification aids in surgical approach selection.
