Nuchal rigidity with sudden severe headache most strongly suggests which conditions?

• A. Subarachnoid hemorrhage or meningitis
• B. Migraine
• C. Tension headache
• D. Cluster headache

Answer: (D)

Nuchal rigidity with a sudden, severe headache signals meningeal irritation from a life-threatening process. The classic scenario is a subarachnoid hemorrhage, often described as a thunderclap headache, where blood in the subarachnoid space irritates the meninges and causes neck stiffness. Meningitis can produce neck stiffness and headache as well, though fever and systemic signs are common clues. In contrast, primary headache disorders don’t typically present with abrupt onset of severe neck rigidity. Cluster headaches involve intense unilateral orbital or temporal pain with autonomic features and agitation, not meningismus. Migraines and tension-type headaches may be painful, but they usually don’t start with rapid, explosive onset accompanied by neck stiffness. So this presentation most strongly points to subarachnoid hemorrhage or meningitis, with subarachnoid hemorrhage being the most critical consideration to rule out first. This is an emergency requiring prompt imaging and evaluation.
