What it is

The meningeal syndrome is the reaction to irritation of the meninges by infection, blood or malignant cells. It combines headache, neck stiffness, photophobia, vomiting and, in meningitis, fever and altered mental status. Bacterial meningitis progresses over hours and is an emergency: clinical suspicion is enough to act, and the cerebrospinal fluid confirms the cause.

Key findings

Kernig and Brudzinski signs: specific, not sensitive.
Photophobia and phonophobia.
Projectile vomiting if raised intracranial pressure is also present.
Nursing: droplet isolation when meningococcus is suspected, neuro checks and seizure watch.

Pathophysiology

Inflammation of the arachnoid, the pia and the subarachnoid fluid activates the pain receptors of the meninges.
The neck muscles contract to stop the inflamed meninges from being stretched: neck stiffness.
Swelling and blocked fluid drainage can raise intracranial pressure.

Common causes

Bacterial: pneumococcus and meningococcus; group B streptococcus in newborns; Listeria in newborns and older adults.
Viral: enteroviruses, the most common and usually benign.
Tuberculous: subacute course with cranial nerve involvement; important in Colombia and in people with HIV.
Fungal: Cryptococcus in people with advanced HIV.
Non-infectious: subarachnoid haemorrhage, carcinomatous meningitis, drugs.

Tests that confirm it

Cerebrospinal fluid analysis (cells, glucose, protein, Gram stain and culture) defines the cause.
Early blood cultures; CT should not delay care for bacterial meningitis.

Test yourself

Think of the answer, then tap the question to see it.

Which three classic findings make up the infectious meningeal syndrome?

Headache, fever and neck stiffness; altered mental status is often added in bacterial meningitis.

What does a meningeal syndrome with sudden headache and no fever suggest?

A subarachnoid haemorrhage, investigated urgently with a head CT.

Which cause of subacute meningitis with cranial nerve involvement matters in Colombia?

Tuberculous meningitis, especially in people with HIV or malnutrition.
