Which of the following is the most likely diagnosis? A 70-year old man comes to the emergency department 30 minutes after the onset of weakness, nausea, and lower abdominal and back pain that radiates to the lower extremities. He appears pale and has a cold sweat. Pulse is 110/min and blood pressure is 90/60 mm Hg. Pulses in the lower extremities are weak. A faint bruit is heard in the lower abdomen. Muscle stretch reflexes are normal in both lower extremities.
A. Acute compression fracture of the L-3 vertebral body B. Herniated L-3 to L-4 intervertebral disc C. Leaking aortic aneurysm D. Perforated rectum E. Perforated sigmoid colon
Correct answer is option C – aortic aneurysm Aortic aneurysm is the dilation (ballooning) of the aorta to greater than 1.5 of the normal size.
They are usually symptoms less except when it ruptures. Aortic aneurysm is most common in the abdominal aorta. A ruptured aortic aneurysm leads to leaking of blood internal structures within the area of rupture. It presents with sudden and intense abdominal or back pain, weak pulses in lower extremities, faint bruit in the lower abdomen. The blood pressure also falls due internal bleeding in the patient. Aortic aneurysm rupture are usually fatal, more than half of people with a rupture die before they get to the hospital.

The correct answer to this question is C. Aortic aneurysms are most common in males aged 60 years or older. The pain is caused by blood that leaks from the aorta that creates pressure in the tissue surrounding the aorta (which runs down the center of your body).
Aortic aneurysms can be caused by hardened arteries, infection, or injury. They are extremely dangerous because they cause internal bleeding that is usually fatal. Eight out of 10 suffers from this condition. You can help prevent aortic aneurysms by avoiding smoking and drug use, oral contraceptives, and an unhealthy diet.
