CT and MR images of AML with infiltration in the kidneys and kidney biopsy findings (A, B) The 3 images in the top row and the 3 images in the bottom row each show roughly the same cross-sectional planes. The images from left to right are from computed tomography (CT), magnetic resonance diffusion-weighted imaging (DWI), and apparent diffusion coefficient (ADC) mapping. The arrows indicate the location of the lesion. In all cross-sections, no obvious abnormalities were observed on CT; however, on MRI, mass-like lesions displaying high signal intensity on DWI and low signal intensity on the ADC map were clearly localized in the superficial kidney cortex. (C) Numerous atypical cells with irregularly contoured, enlarged nuclei extensively infiltrating the collagen fiber bundles within the kidney capsule (hematoxylin‒eosin stain; original magnification, ×400). (D) Atypical cells in peritubular capillaries (hematoxylin‒eosin stain; original magnification, ×400). Abbreviations: ADC, apparent diffusion coefficient; CT, computed tomography; DWI, diffusion-weighted imaging; HE, hematoxylin‒eosin, MRI, magnetic resonance imaging.
