06_00124 Dakota G Renal mass

Sonographic Differential Diagnosis

Right kidney mass. May represent necrotic abscessation given the calculus. Passage of calculus may predispose to an abscess or more likely represent a neoplastic event.
The left kidney appears structurally viable enough to sustain metabolic need.
Ultrasound-guided FNA +/- culture and cytology would be recommended or right nephrectomy.

Image Interpretation

The left kidney was uniform, without calculus, and measured 3.75 cm. The cranial pole of the right kidney presented a hypoechoic mass that measured 1.9 x 1.26 cm with disruption of the corticomedullary junction and capsular swelling. There was no blood flow to the mass. The right kidney presented a calculus at the corticomedullary junction. The right kidney measured 3.76 cm. FNA of the right kidney is recommended.
