Renal tubular ectasia

Case contributed by Dr Matt A. Morgan

Presentation

History of a single episode of urolithiasis. Currently asymptomatic. Evaluation per request of urology.

Patient Data

Age: 50-55 years old
Gender: Female
Fluoroscopy

There are not calcifications in either kidney... and a recent (within a month) CT of the abdomen and pelvis did not show any renal stones.

On the IVP, there is exaggerated "strandy" enhancement of the medullary pyramids with a "paintbrush" appearance. No filling defect in either kidney.

Case Discussion

The appearance is compatible with renal tubular ectasia. This "paintbrush" appearance overlaps with medullary sponge kidney, and the difference between the two is really one of degree and symptoms.
