Renal pelvic calculus and pyelitis cystica

Case contributed by Dr Roberto Schubert


Macrohaematuria, right flank pain.

Patient Data

Age: 65 years
Gender: Male

The right renal pelvis containing the calculus shows a thickened wall with unsharp delineation from the surrounding fat tissue. In some sections, there are small bubbly, centrally hypodense structures in the renal pelvic wall. Urothelial malignancy could not be excluded.

Case Discussion

Pyelitis or ureteritis cystica is not a typical imaging diagnosis. In this case, it was confirmed with ureterorenoscopy.
