Striated nephrogram

Striated nephrogram, originally described on plain film urography, but just as easily seen on CT urography represents linear bands of contrast extending from the medulla of the kidney towards the cortex.

Pathology

Striations result from stasis and concentration of contrast material in oedematous or necrosed tubules. It demonstrates increasing attenuation over time 3.

Aetiology

It is seen in a number of conditions:

Unilateral striated nephrogram
