[A tricky issue for the ultrasound technician].
A 72-year-old woman presented with chronic renal failure and diffuse abdominal pain. On ultrasonography the right kidney showed an uncommon site, whereas the left kidney presented a pseudo mass on its lower pole. MRI detected a multiple anatomic anomaly: dislocation of the right kidney, renal fusion, malrotation of the left kidney. This anatomic anomaly is called ''sigmoid kidney'': it can be asymptomatic or result in genitourinary diseases.
