Figure 1 Contribution of diffusion-weighted magnetic resonance imaging in the detection of the subclinical stage of IgG4-related acute TIN. (a) Color-coded map of T2-weighted and diffusion-weighted imaging displayed multiple bilateral areas of water movement restriction (red arrows) related to hypercellular content of the renal parenchyma associated with marked thickening of the anterior cortex. Areas of normal renal parenchyma (blue arrow) are also shown. The white arrow indicates ultrasound-guided biopsy of the right kidney. (b) Massive interstitial inflammation with extensive renal tubule destruction and apparently normal glomeruli. (Hematoxylin and eosin staining; original magnification × 400.)
