DIAGNOSTIC CRITERIA

Clinical

  • Signs and symptoms of complications:
    • Peri-orbital swelling and fever.
  • Signs of meningeal irritation:
    • Neck stiffness, positive Kernig’s and Brudzinski’s signs.
  • Signs of increased intracranial pressure:
    • Hypertension, bradycardia, papilloedema and headache.
  • Signs of involvement of orbital structures:
    • Periorbital oedema, erythema, chemosis, proptosis, vision loss and ophthalmoplegia.
  • Signs of brain involvement:
    • Neurological signs, ataxia, paresis, paralysis, convulsions and altered level of consciousness.

Investigations

  • CT scan of brain, sinuses and orbits may show opacities and complications.
  • CT scan will show if there is involvement of intracranial structures, e.g. brain abscess and intraorbital involvement.
