Brain Abscess l: Introduction01:26

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,...
The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Summary
This summary is machine-generated.

Varicella-zoster virus (VZV) infection in an elderly woman led to eye movement issues and vision loss. This rare complication caused recurrent strokes affecting brain arteries, resulting in hemiparesis and aphasia.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Ophthalmology

Background:

  • Varicella-zoster virus (VZV) is a common human herpesvirus.
  • Ophthalmoplegia and visual loss are rare neurological complications of VZV reactivation.

Observation:

  • A 75-year-old woman presented with trigeminal VZV infection.
  • She developed ophthalmoplegia and subsequent visual loss.
  • Recurrent cerebral infarctions involving intracranial arteries were noted.

Findings:

  • Medical therapy improved ophthalmoplegia.
  • The patient subsequently developed right hemiparesis and aphasia.
  • Cerebral infarctions involved both small and large intracranial arteries.

Implications:

  • This case highlights a severe neurological sequela of VZV infection.
  • It underscores the importance of considering VZV in cerebrovascular events, especially in the elderly.
  • Prompt diagnosis and management are crucial for potentially mitigating further neurological damage.
