On further questioning, she reports she is previously healthy, takes no medications, and has no allergies. She says that her blood pressure has been recently constantly elevated on several occasions during different times of the day. Her vital signs show a temperature of 36.1 degrees C (97 degrees F), a heart rate of 82 bpm, and a blood pressure measuring 170/90 mmHg. The remainder of her physical examination is unremarkable. Appropriate work-up is initiated; her abdominal computed tomography (CT) scan shows small stenoses along the left renal artery with areas of small aneurysms causing a "string of beads" appearance. An image of her CT scan is shown below. What is the most likely diagnosis of this patient's condition?
