Abstract:
We present the case of a 51-year-old Japanese man with immunoglobulin G4-related inflammatory abdominal aortic aneurysm (AAA). A computed tomography scan showed a 60-mm AAA with inflammatory aortic wall thickening and bilateral hydronephrosis. We did not administer steroid therapy but undertook endovascular aneurysm repair. Postoperatively, inflammation of the aorta and hydronephrosis ameliorated without steroid therapy. The treatment of immunoglobulin G4-related inflammatory AAA is still debated. We achieved good clinical results with endovascular repair alone.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
