The MRI features of renal inflammatory pseudotumor: A case report and literature review

Abstract

Rationale: Inflammatory pseudotumor is rare observed in renal immunoglobulin G4-related disease. Patient concerns: A 65-year-old female presented with a mass in the right kidney which was found in physical examination. Diagnoses: Based on the imaging findings and clinical manifestations, we preliminarily judged that the mass of the right kidney was renal cell carcinoma. Interventions: The patient finally underwent total nephrectomy. Outcomes: The final result of microscopic pathological examination is renal inflammatory pseudotumor. Lessons: There are some characteristics on magnetic resonance imaging of renal inflammatory pseudotumor, which can improve diagnosis rate by combining with medical history and clinical manifestations.
