What is an aneurysm?

• A. An infection of the spinal cord
• B. An enlargement of an artery due to weakness or injury
• C. A defect in heart structure
• D. A virus causing brain inflammation

Answer: (B)

An aneurysm is defined as an enlargement or bulging of an artery that occurs due to a weakness or injury in the arterial wall. This condition can occur in various arteries in the body and is particularly concerning because it can lead to serious complications, such as rupture or dissection, which may result in life-threatening bleeding. The understanding of aneurysms is crucial for diagnosing and managing cardiovascular conditions effectively. Factors such as high blood pressure, atherosclerosis, or genetic predispositions can contribute to the formation of an aneurysm, highlighting the importance of monitoring health for those at risk. In contrast, the other options refer to different medical conditions: an infection of the spinal cord is known as myelitis, a defect in heart structure pertains to congenital heart diseases or acquired heart conditions, and a virus causing brain inflammation refers to encephalitis. Each of these conditions involves distinct pathophysiological mechanisms and implications that do not align with the definition of an aneurysm.
