Conference Presentation Abstracts
Context: IgG4-related interstitial nephritis (IRIN) can present as either a renal mass or with acute kidney injury (AKI). The goal of this study was to present our 4 IRIN cases with different clinical scenarios.
Design: Over the past 5 years, we identified 4 cases of IRIN. Each case was evaluated.
Results: Case 1 involved a 60-year-old man with a 3-cm kidney mass. The core biopsy revealed storiform fibrosis and increased IgG4-positive plasma cells (>30 per high-power field), thus diagnosed as IRIN. Case 2 involved a 69-year-old man with medical history of polymyalgia rheumatica and low complements who developed AKI …
