The given image shows linear bands of contrast extending from the medulla of the kidney towards the cortex of the kidney, called a
striated nephrogram seen on plain film and CT nephrography. Autosomal dominant polycystic kidney disease (
ADPKD) shows
swiss cheese nephrogram, not striated nephrogram.
Conditions which show striated nephrogram include:
- Unilateral:
- Acute ureteric obstruction
- Acute pyelonephritis
- Acute renal vein thrombosis
- Acutely following renal contusion
- Acute radiation therapy to the kidney
- Bilateral:
- Autosomal recessive polycystic kidney disease (ARPKD)
- Acute pyelonephritis (if it is bilateral)
- Acute tubular obstruction
- Acute tubular necrosis
- Hypotension
