IgG4-Related Renal Lesions Detected by Delayed 18F-FDG PET/CT Scan

Clin Nucl Med. 2017 Jan;42(1):66-67. doi: 10.1097/RLU.0000000000001427.

Abstract

Multiple renal lesions, which showed clearly demarcated low densities on contrast-enhanced CT, were revealed in a 56-year-old woman. The F-FDG avidity of the renal lesions was equal to or mildly higher than that of the renal cortex on the routine PET/CT scan, but significantly higher on the delayed scan. IgG4-related disease with renal involvement was confirmed subsequently by the measurement of serous IgG4 and the pathology of renal lesion.
