title: Rare renal pseudotumor associated with chronic glomerulonephritis mimicking renal cell carcinoma.
abstract: We describe a unique case of chronic glomerulonephritis that simulated a renal neoplasm observed on abnormal imaging. Histologic examination of the resected specimen supported the assumption that the observed mass lesion resulted from regional sparing in the development of chronic glomerulonephritis. We believe this case is the first to show the etiology of pseudotumor as an extremely uncommon manifestation of chronic glomerulonephritis by histologic examination.
