Ultrasound of the kidney shows hyperechoic (bright) renal medulla. Medullary nephrocalcinosis is caused by a number of different underlying diseases. The most common single condition is distal renal tubular acidosis. However, tubulopathies, hyperoxaluria, hypercalciuria, vitamin D overdose, and other syndromes can also cause this finding.

Abdominal x-ray in an infant with renal failure shows a dense appearance of the kidneys. This dense nephrogram was caused by retention of contrast after an interventional procedure. A bilateral dense nephrogram can be caused by hypotension (related to sepsis or an allergic reaction to contrast). Other causes include renal artery stenosis, acute kidney injury, or urinary obstruction.
