title: A case of Takayasu arteritis complicated with glomerulonephropathy mimicking membranoproliferative glomerulonephritis.
abstract: We report on a 65-year-old Japanese woman with Takayasu arteritis who developed severe proteinuria, hypertension, and renal dysfunction. Renal angiography demonstrated moderate irregular narrowing of both renal arteries. Renal biopsy showed glomerulonephropathy mimicking membranoproliferative glomerulonephritis (MPGN) with glomerular capillary wall thickening ("double contour") accompanied by mesangial cell proliferation and moderate increase of mesangial matrix without deposits of C3. Electron microscopy showed no subendothelial deposit and no circumferential mesangial interposition (CMI), and these findings are different from MPGN. In this report we present a case of Takayasu arteritis associated with glomerulonephropathy mimicking MPGN.
