Objective:
To explore the imaging diagnosis of xanthogranulomatous pyelonephritis (XGP), especially the value of angiography.
Methods:
Combined with literature review, a retrospective analysis was conducted of the imaging data of 6 pathologically confirmed XGP cases as an attempt to define the preoperative diagnosis of the disease.
Results:
Four cases of XGP were diagnosed preoperatively, and 2 were misdiagnosed as renal abscess. Renal arteriography revealed more characteristic changes, and the diagnosis of XGP relied on the clinical presentations and multiple imaging examinations.
Conclusion:
Renal arteriography is the principal approach in the diagnosis and differential diagnosis of XGP.
