Worst headache of their life could indicate which condition?

• A. Migraine
• B. Aneurysm
• C. Sinusitis
• D. Tension headache

Answer: (B)

A sudden, thunderclap headache described as the worst of life points to a subarachnoid hemorrhage from a ruptured intracranial aneurysm. This is an emergency because bleeding into the space around the brain can cause rapid brain injury or death. The hallmark is abrupt onset with peak intensity within seconds, often with neck stiffness, sensitivity to light, nausea, vomiting, or altered consciousness. Because of this danger, urgent evaluation is needed—start with a noncontrast CT scan to look for blood. If the CT is negative but suspicion remains high, a lumbar puncture is done to detect bleeding markers like xanthochromia.

In contrast, migraines usually involve throbbing pain that may progress over minutes to hours and is often accompanied by aura, photophobia, or nausea, but they don’t typically present as an immediate, maximal intensity event. Sinusitis headaches arise from sinus inflammation and include facial pressure and nasal symptoms rather than a sudden thunderclap. Tension headaches are described as a band-like, steady pressure and are not characterized by an abrupt, severe onset.

So the description most strongly signals an aneurysm causing subarachnoid hemorrhage.
