In a patient older than 50 with back pain, which condition is a high‑priority life-threatening concern?

• A. Osteoarthritis
• B. Aortic aneurysm
• C. Degenerative spondylosis
• D. Disc herniation

Answer: (B)

When back pain appears in someone over 50, the priority is ruling out potentially fatal vascular conditions, especially an abdominal aortic aneurysm with risk of rupture. An aneurysm can grow silently and then rupture suddenly, causing rapid deterioration. The red flags include sudden, severe back or abdominal pain, sometimes described as tearing, along with signs of shock such as low blood pressure, rapid pulse, or pale, clammy skin. If you suspect this, treat it as a medical emergency: secure IV access with large-bore lines, monitor the patient closely, and obtain imaging promptly. Bedside ultrasound can quickly suggest an aneurysm; CT angiography is preferred if the patient is stable to plan definitive repair, with urgent surgical consultation. Osteoarthritis and degenerative spondylosis are common in this age group and usually produce chronic, mechanical back pain that worsens with activity and improves with rest, without causing abrupt systemic instability. Disc herniation can cause localized or radicular leg pain and neurological symptoms, but it does not typically present as a life-threatening vascular catastrophe.
