A renal unit saving approach to IgG4 related periureteral mass mimicking malignant ureteral tumor

Abstract

Immunoglobulin G4-related disease (IgG4-RD) is a rare disease with few cases mimicking ureteral tumour identified after the ablative surgery. We report a case of IgG4-RD that presented as a ureteral mass which was diagnosed prior to surgery and managed conservatively. A 63-year-old man presented with prior diagnosis of the right ureteric tumour but a radiological review suspected it could be something else. The patient underwent laparoscopic biopsy from the periureteric mass. Biopsy reported to be IgG-4 disease and managed conservatively. This case highlights the rare possibility of IgG4-disease mimicking ureter tumour and if diagnosed prior to extirpative surgery can result in salvage of the kidney.
