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,...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Dentistry

Background:

  • Orbital infections pose a risk of permanent morbidity and potentially fatal intracranial complications.
  • Common origins include paranasal sinus infections, skin infections, and trauma; rarer causes like dacryocystitis and odontogenic infections are less documented.

Observation:

  • A patient presented with proptosis, decreased visual acuity, and impaired ocular motility following endodontic treatment.
  • Clinical signs included facial pain, sinusitis symptoms, fever, and erythema, with CT revealing sinus opacities and an orbital abscess.

Findings:

  • Computed tomography confirmed extensive sinus involvement and an apical lesion linked to dental procedures.
  • Evidence of pus in the medial orbital wall indicated a severe orbital infection originating from dental sources.
