Overview
Physical Examination
The suspicion of meningitis is generally based on the nature of the symptoms and findings on physical examination. Meningitis is a medical emergency, and referral to hospital is indicated. If meningitis is suspected based on clinical examination, early administration of antibiotics is recommended, as the condition may deteriorate rapidly. In the hospital setting, initial management consists of stabilization (e.g. securing the airway in a depressed level of consciousness, administration of intravenous fluids in hypotension or shock), followed by antibiotics if not already administered.
Nuchal rigidity is typically assessed with the patient lying supine, and both hips and knees flexed. If pain is elicited when the knees are passively extended (Kernig's sign), this indicates nuchal rigidity and meningitis. In infants, forward flexion of the neck may cause involuntary knee and hip flexion (Brudzinski's sign). Although commonly tested, the sensitivity and specificity of Kernig's and Brudzinski's tests are uncertain.[1]
In "meningococcal" meningitis (i.e. meningitis caused by the bacteria Neisseria meningitidis), a rapidly-spreading petechial rash is typical, and may precede other symptoms. The rash consists of numerous small, irregular purple or red spots on the trunk, lower extremities, mucous membranes, conjunctiva, and occasionally on the palms of hands and soles of feet.
