Background

Retroperitoneal fibrosis (retroperitoneal fibrosis) involves an inflammatory fibrous retroperitoneal development that surrounds the abdominal aorta.

Results

creatinine at 6.28 mg/dL

high level of a waste product, indicating severe kidney damage

More results

Oftentimes, extension into the iliac arteries and ureters is seen, which can cause hydronephrosis and lead to renal failure.

A case of idiopathic retroperitoneal fibrosis in a 73-year-old male will be examined.

The patient presented with bilateral flank pain, hematuria, and low urine output that had lasted for about 4 days.

More results

A 5.1 cm abdominal aortic aneurysm extending into the bilateral common iliac arteries was seen on CTA of the abdomen and pelvis.

“

Conclusion

On follow up, CTA imaging showed a reduction of the mass as well as return of inflammatory markers to baseline.
