A 30-year-old woman presents with a sudden severe headache that she describes as "the worst headache of her life." She also complains of neck stiffness and vomiting. On examination, she has photophobia, and there is nuchal rigidity. A non-contrast head CT scan is performed and shows subarachnoid haemorrhage (SAH). What is the most likely cause of her symptoms? A) Migraine B) Tension-type headache C) Intracerebral haemorrhage D)Aneurysmal subarachnoid haemorrhage E) Meningitis Answer: D) Aneurysmal subarachnoid haemorrhage Explanation: The sudden onset of the worst headache of her life, neck stiffness, vomiting, and photophobia in this patient strongly suggests an aneurysmal subarachnoid haemorrhage (aSAH). This is a medical emergency, and prompt evaluation and treatment, such as neurosurgical intervention to secure the aneurysm, are necessary.
