Summary
Multilocular cystic nephroma, a rare kidney tumor, can unusually present within the renal pelvis. Nephron-sparing surgery via simple excision offers a successful treatment for this condition.
Area of Science:
- Urology
- Nephrology
- Oncology
Background:
- Multilocular cystic nephroma (MCN) is a rare benign renal tumor.
- Typical MCNs arise from the renal parenchyma.
- Unusual presentations require careful diagnostic and therapeutic consideration.
Observation:
- A young woman presented with hematuria and right lumbar pain.
- Imaging revealed a cystic mass primarily involving the renal pelvis.
- Surgical exploration confirmed the lesion's location within the renal pelvis.
Findings:
- Pathologic analysis confirmed the diagnosis of multilocular cystic nephroma.
- The patient underwent a nephron-sparing procedure involving simple excision.
- No recurrence was observed during a 10-year follow-up period.
Implications:
- Multilocular cystic nephroma can present with an unusual intrapelvic localization.
- Nephron-sparing surgery, specifically simple excision, is an effective treatment.
- This case highlights the importance of considering MCN in the differential diagnosis of renal pelvic masses.
