Figure 1

(a) Patchy low-density lesion in contrast-enhanced CT scan of IgG4-RKD (arrow). (b) Nodule lesion in renal parenchyma of IgG4-RKD (arrow). (c) Arrow is pointed at the thickening perirenal capsule of an IgG4-RKD patient. (d) Repeated contrast-enhanced CT scan revealed radiological remission of an IgG4-RKD patient after 1-year treatment. Arrow is pointed at the low-density lesion area before and after treatment. (e) Repeated CT scan of IgG4-RKD after 2 years. The swelling of the bilateral kidney prominently ameliorated. (f) PET-CT of an IgG4-RKD patient presenting with unilateral renal mass with high uptake of 19F-FDG (arrow pointed at the mass).
