Question

Image below highlights jugular foramen. Which of the following structures do not pass through the marked structure “A”?

Answer 1

This question checks the distinction between vasculitic, palpable purpura and simple capillary-fragility, non-palpable purpura.

Scurvy: the correct exception, vitamin C deficiency weakens capillaries without inflaming the vessel wall, giving flat, non-palpable purpura.
Acute meningococcemia: not the exception, it produces palpable, often necrotic purpura through vasculitis and disseminated intravascular coagulation.
Vasculitis: not the exception, vessel-wall inflammation is the textbook cause of palpable purpura.
Essential mixed cryoglobulinemia: not the exception, immune-complex deposition causes leukocytoclastic vasculitis with palpable purpura.

Correct answer: Scurvy.
