Area of Science:

  • Ophthalmology
  • Neurology
  • Trauma Surgery

Background:

  • Penetrating trauma from projectiles like BBs can lead to serious complications.
  • Intravascular migration of foreign bodies poses a significant risk of systemic and localized injury.

Observation:

  • A 9-year-old boy presented with a chest BB gun injury.
  • Imaging revealed the BB lodged in the right internal carotid artery.

Findings:

  • The patient developed monocular blindness in the right eye.
  • Neurological deficits included a right third nerve palsy, left hemiparesis, and left homonymous hemianopia.

Implications:

  • BB gun injuries can have devastating ophthalmologic and systemic consequences.
  • Embolization of projectiles necessitates prompt diagnosis and management to prevent severe outcomes.
  • This case underscores the importance of considering projectile migration in penetrating trauma evaluations.
