Introduction: The chronic, cystic inflammation of the renal pelvis is a rare condition and the number of international publications on the topic is low. Moreover, to date there have not been any case studies concerning the entity published in the Hungarian literature.
Case report: A 74-year-old female patient was admitted to our clinic with microscopic haematuria. The CT urography study showed a tumour suspect lesion in the right renal pelvis, while the cystoscopy was negative. Urine cytology showed no sign of malignancy. We performed a radical ureteronephrectomy, and the histology revealed chronic inflammation of the renal pelvis, pyelitis cystica.
Conclusions: During the investigation of renal pelvic masses, CT urography gives a precise diagnosis in most cases, though under certain circumstances, preforming a diagnostic ureterorenoscopy may be appropriate. We felt that our case was important to showcase, because it shines a light on the potential differential diagnostic problems of renal pelvic masses.
