Figure 35

Glomeruli in segmental arterial mediolysis. The glomerulus in (a) exhibits an in tandem arrangement of hyperplastic mesangial cells in the glomerular stalks. Glomerulus in (b) in addition to mesangial hyperplasia also shows at the red arrow a segmental aggregation of matrix material obscuring the adjacent glomerular loop.
