Anatomy of the Brain: Ventricles

5.5K
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.

Summary
This summary is machine-generated.

Cavernous malformations (CMs) are common brain lesions. While microsurgery offers a cure, radiosurgery provides a safer alternative for reducing rebleeding risks over time.

Area of Science:

  • Neurology
  • Neurosurgery
  • Radiology

Background:

  • Cavernous malformations (CMs) are prevalent intracerebral vascular anomalies, increasingly detected with MRI.
  • CMs can be sporadic or familial, with familial types potentially exhibiting multiple lesions requiring ongoing monitoring.
  • Many sporadic CMs are asymptomatic, but supratentorial lesions commonly present with epilepsy.

Purpose of the Study:

  • To review the characteristics and treatment options for cavernous malformations.
  • To compare the efficacy and risks of microsurgery versus radiosurgery for CM treatment.

Main Methods:

  • Review of literature on cavernous malformations.
  • Analysis of treatment outcomes for microsurgery and radiosurgery.

Main Results:

  • Microsurgery is curative but associated with significant risks of complications, patient deterioration, and incomplete removal.
  • Radiosurgery, demonstrated over two years, effectively reduces rebleeding risk with lower complication rates compared to microsurgery.
  • Brainstem CMs pose a higher risk, including potential lethality, necessitating careful treatment considerations.

Conclusions:

  • Both microsurgery and radiosurgery have distinct roles in managing cavernous malformations.
  • Radiosurgery offers a viable alternative to microsurgery, particularly for reducing rebleeding risks without the associated surgical complications.
