case_images: CT images of the renal pelvic lesions and histological image of the inguinal lymph node biopsy specimen. Dynamic contrast-enhanced CT images obtained during the arterial (A) and equilibrium (B) phases demonstrated renal pelvic lesions (red arrows) with enhancement in the equilibrium phase. (C) Lymphatic tissue with preserved follicular structure and enlarged interfollicular zones (Haematoxylin and Eosin staining, x100). (B) Sheets of mature plasma cells within the interfollicular zones (Haematoxylin and Eosin staining, x400)

case_images: Body CT with contrast media revealed multiple centrilobular ground glass opacities in the lungs bilaterally, multiple enlarged lymph nodes in the neck, axilla, supraclavicular area, inguinal region, hilar region and mediastinum, and enhanced soft tissue density surrounding the renal pelvises bilaterally (Fig. 1A and B). We re-evaluated the inguinal lymph node biopsy specimen obtained at the previous hospital, and the histological examination showed sheets of mature plasma cells within the interfollicular zones of the lymph node, which was consistent with MCD (Fig. 1C and D).
