Unilateral nephrocalcinosis

A 37-year-old man with unremarkable medical history was referred to our nephrology department for unilateral left nephrocalcinosis, incidentally discovered on imaging for chronic low back pain (Figure  1, arrow). On clinical examination, we were struck by a lateralized overgrowth of the left hemibody (Figure 2). An abdominal computed tomography scan with 3-dimensional reconstruction made the diagnosis of medullary sponge kidney (with precaliceal canalicular ectasia predominantly seen in the lef t kidney) and did not show any other abnormality (Supplementary Figure S1).
