[Imaging diagnosis of xanthogranulomatous pyelonephritis: report of 6 cases].
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.


CONCLUSIONS
Renal arteriography is the principal approach in the diagnosis and differential diagnosis of XGP.
