Abstract:
The inflammatory variant of aortic aneurysms has 3 unique features: marked thickening of the aneurysm wall, fibrosis of the adjacent retroperitoneum, and rigid adherence of the adjacent structures to the anterior aneurysm wall. Abdominal tenderness with or without a pulsatile abdominal mass is the most common finding, although it is present in only about 33% of patients. Systemic symptoms, such as fever, malaise, and weight loss, are reported in about 20% to 50% of patients. A contrast-enhanced computed tomography scan, magnetic resonance imaging, and a transesophageal echocardiogram are among the best modalities to evaluate for inflammatory thoracoabdominal aneurysm, but a transthoracic echocardiogram can frequently be very suggestive. Medical treatment options include corticosteroids or other anti-inflammatory and immunosuppressive therapies. Surgical intervention usually consists of a transperitoneal approach with infrarenal aortic clamping. This case review describes a 64-year-old woman with a history of hypertension and dyslipidemia who presented with anemia, lower back pain, and a recent 30-pound weight loss.
