• Question 59:

  A third-year medical student is examining a patient who has acute onset of abdominal pain. The patient is a 65-year-old smoker with HTN and DM who has had dull abdominal pain gradually building for the last 12 hours. It is not related to food nor relieved by taking famotidine. On physical examination, auscultation reveals a bruit. Palpation shows a pulsatile mass. While lightly palpating the epigastrium, the patient suddenly becomes hypotensive and passes out.

  What is the most likely diagnosis?

  A. Hemorrhagic gastritis
  B. Narcolepsy
  C. Ruptured abdominal aortic aneurysm
  D. Ruptured peptic ulcer
  C. Ruptured abdominal aortic aneurysm

  ---

  A bruit and pulsatile abdominal mass are hallmark signs of an abdominal aortic aneurysm (AAA). The fact that the medical student was palpating the area and the patient passed out was a coincidence; however, syncope in the setting of the AAA is rupture until proven otherwise. Ruptured peptic ulcer would have more severe and sharp abdominal pain. Hemorrhagic gastritis could cause syncope, but the bleeding would cause emesis, and the patient is supine, so orthostasis is not of concern. Narcolepsy would not have hypotension. This patient's abdominal pain was from the AAA beginning to rupture and was dull and gradual in onset.
