Correct Answer - D Ans. d. Subarachnoid hemorrhage The most likely diagnosis here is a subarachnoid bleed (SAH).
The most common cause is trauma and is managed conservatively. The second most common cause is a rupture of a berry aneurysm.
The typical presentation of a subarachnoid hemorrhage includes a ‘thunderclap’ headache.
Meningitic features of neck stiffness and photophobia often develop over hours.
Computed tomography (CT) is the investigation of choice.
Lumbar puncture should be performed if the CT scan fails to establish the diagnosis of SAH; it shows a xanthochromic blood picture.
Delayed ischemic neurological deficit (DIND) is attributed to vasospasm of the cerebral vasculature typically developing 3–10 days following ictus. It is the main cause of a poor outcome
Endovascular treatment ("coiling") is generally preferred over craniotomy and clipping for aneurysms amenable to this approach.
