Glomerulomegaly

A normal glomerulus (left) and hypertrophied glomerulus (glomerulomegaly, right). Glomerulomegaly is an adaptive response to decreased nephron number (e.g. prematurity) and/or increased demand (e.g. obesity). Patients with glomerulomegaly may have sub-nephrotic or nephrotic-range proteinuria, but other features of nephrotic syndrome are rare. Images courtesy of Patrick Walker, MD.
