Bilateral kidney malrotation

Case contributed by Dr Arthur Daire

Presentation

Features of right pyelonephritis (right loin pain, fevers). Urine cultures were negative. A right renal mass was suspected on initial ultrasound (not shown).

Patient Data

Age: 8 years
Gender: Male
CT

The study demonstrated bilateral malrotated kidneys, in which the hila face anteriorly. This is seen in both the portal venous and delayed phases.

Case Discussion

This study demonstrated renal malrotation, which is a normal variant. Poor drainage of the collecting system because of the position of the renal pelvis, can predispose the kidney to infection (due to urinary stasis) and stone formation.
