title: PET/CT images of bilateral diffuse intraglomerular metastasis of malignant melanoma.
abstract: Intraglomerular metastasis is a very rare condition with an underlying cause that is not yet well understood. We present the 18F-FDG PET/CT images of histologically proven intraglomerular metastases from newly diagnosed malignant melanoma with positive sentinel lymph node metastases. During the initial diagnostic evaluation period, the patient also had a sudden increased serum creatinine level. FDG PET/CT demonstrated diffuse glomerular FDG uptake unlike typical physiologic pelvicaliceal activity. Renal biopsy revealed diffuse crescentic lesions containing metastatic melanoma cells.
