Findings
- Enlarged left kidney with diffuse loss of corticomedullary differentiation
- Hypoechoic lesion at the junction of the upper pole and interpolar region of the left kidney measuring 2.2 x 1.9 cm with a thick, echogenic rim, posterior acoustic enhancement, and no internal Doppler flow
- Mild fulness of the left renal pelvis with urothelial thickening
- Mild cortical thinning in the upper pole of the right kidney with adjacent calyceal enlargement
- Mild right hydroureteronephrosis with urothelial thickening
- Mild circumferential mural thickening of the urinary bladder with layering echogenic material
Diagnosis
Pyelonephritis with renal abscess
Sample Report
Findings consistent with diffuse left pyelonephritis. A hypoechoic lesion at the junction of the upper pole and interpolar region of the left kidney measuring 2.2 x 1.9 cm is concerning for a renal abscess. Recommend follow-up ultrasound after treatment to ensure resolution of these findings and to better assess the renal parenchyma.
Mild fulness of the left renal pelvis and mild right hydroureteronephrosis with bilateral urothelial thickening in addition to bladder wall thickening, likely relating to urinary tract infection. No obstructing ureteral calculus identified.
Likely mild cortical scarring at the upper pole of the right kidney with adjacent calyceal enlargement, which may represent sequela of prior infection.
