title: Case report: Renal pseudotumours mimicking tumour recurrence after partial nephrectomy.
abstract: Partial nephrectomy and tumour enucleation are increasingly accepted as an organ sparing approach for small renal cell carcinomas. Repeated computed tomography or sonography for the early detection of tumour recurrence are mandatory during the follow-up. We report two cases of renal pseudotumour mimicking a tumour recurrence: one case is related to the pseudotumoral appearance on sonography of a tumour defect filled by a fatty flap, and the other to the relative migration of an accessory spleen into the site of the cuneiform nephrectomy. The recognition of renal pseudotumours following partial nephrectomy prevents confusion with tumour recurrence on follow-up examinations.
