ABSTRACT

Diagnosis: Nephrolithiasis with "twinkle" artifact on color Dopler ultrasound

History: 59 yo woman referred for renal ultrasound.

Findings: Transverse gray-scale view of the lower pole of the right kidney demonstrates a small bright echogenic focus with possible shadowing suggestive of a nonobstructing renal stone. Color Doppler imaging shows a “twinkle” artifact confirming this echogenic focus is a renal calculi. Unenhanced axial CT from the same patient obtained a few months later, demonstrates the non-obstructing renal calculi in the lower pole of the right kidney.

Ddx: • Nephrolithiasis • Intrarenal gas • Renal artery calcification • Calcified sloughed papilla • Calcified transitional cell tumor

Dxhow: Characteristic Imaging Findings

No MeSH data available.
