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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
