Presentation
Fever, weakness, and right flank pain - few days.
Patient Data
The right kidney (115 x 45 mm) shows normal corticomedullary differentiation, mild fullness of the renal pelvis, pelvicalyceal urothelial thickening, and multiple heterogeneous hypoechoic avascular parenchymal lesions (about 8 to 10 in number) with/ without internal mobile echoes. A well-defined wall is present in the larger lesions. The largest lesion measures 24 x 16 x 15 mm - 3.3 cc. These lesions involve upper-inter-lower pole regions and anterior-lateral-posterior parenchyma. No extra-renal extension/ perinephric fluid/ renal calculus. Patent renal artery and vein.
The left kidney (113 x 42 mm) shows normal corticomedullary differentiation. No calculus, back pressure changes, or mass lesions.
The urinary bladder is distended without calculus/ wall thickening.
Case Discussion
The patient with fever, weakness, and right flank pain shows right renal abscesses. Further laboratory workup suggested a urinary tract infection. The patient responded to conservative treatment.
