**Core Concept**
Papilloedema is the swelling of the optic disc due to increased intracranial pressure (ICP). Normal-appearing ventricles on CT scan suggest that the cause of increased ICP is not related to obstructive hydrocephalus.
**Why the Correct Answer is Right**
The presence of papilloedema in the absence of hydrocephalus suggests that the cause of increased ICP is likely due to other factors such as space-occupying lesions, intracranial tumors, or idiopathic intracranial hypertension. The normal ventricles on CT scan rule out obstructive hydrocephalus as a cause of increased ICP.

**Clinical Pearl / High-Yield Fact**
In a patient with papilloedema, it is essential to rule out space-occupying lesions and intracranial tumors, which can cause increased ICP. A normal CT scan does not rule out other causes of increased ICP, and further investigation may be necessary to determine the underlying cause.
