Summary
Renal pseudotumours can mimic tumor recurrence after partial nephrectomy. Recognizing these benign findings, such as fatty flaps or migrated spleens, is crucial for accurate follow-up imaging in renal cell carcinoma patients.
Area of Science:
- Urology
- Oncology
- Radiology
Background:
- Organ-sparing surgery, including partial nephrectomy and tumor enucleation, is a standard approach for small renal cell carcinomas.
- Post-operative surveillance with imaging (CT or ultrasound) is essential for early detection of tumor recurrence.
Observation:
- Two cases of renal pseudotumors mimicking tumor recurrence after partial nephrectomy are presented.
- Case 1: A pseudotumor formed by a fatty flap filling a surgical defect on sonography.
- Case 2: A pseudotumor caused by the migration of an accessory spleen into the nephrectomy site.
Findings:
- Renal pseudotumors can arise from various post-surgical changes, including fatty tissue infiltration and splenic tissue displacement.
- These benign entities can present imaging characteristics that are difficult to distinguish from malignant recurrence.
Implications:
- Accurate identification of renal pseudotumors is vital to prevent misdiagnosis of tumor recurrence.
- Awareness of these potential pseudotumors can optimize patient management and reduce unnecessary anxiety and interventions during follow-up after nephron-sparing surgery.
