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.

External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Internal Anatomy of the Kidney
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...
