Abdominal aortic aneurysm (AAA) is a medical condition characterized by abnormal enlargement or the ballooning of the aorta, the largest blood vessel in the human body, in the abdomen. AAA usually develops slowly and asymptomatically and becomes a potentially life-threatening condition if left untreated. Although the exact cause of AAA is not always clear, risk factors such as age, sex, smoking, hypertension, and family history may increase the likelihood of developing AAA. It is essential to manage and prevent AAA rupture, which can lead to severe internal bleeding and pose a serious risk to a person's health if not diagnosed in a timely manner and appropriate medical attention. Awareness, early diagnosis and appropriate medical care are critical factors when addressing this condition, providing a glimpse into the complex and critical nature of AAA. The present study describes the case of a patient who applied to the family medicine unit with hypertension and dysuria, and was diagnosed with AAA incidentally.
