27 years old, Male, Reason: assess for perinephric abscess History: MRSA UTI RIGHT KIDNEY: Kidney measures 12.0 cm in length. Normal echotexture. Nohydronephrosis, shadowing calculus or mass.LEFT KIDNEY: Kidney measures 10.3 cm in length. A focal space occupying lesion in the superior anterior portion of the left kidney which appears to extend beyond the expected contours of the kidney. There is blood flow to portions of this space occupying lesion indicating it is at least partially intrarenal with distention of the renal capsule and possible extrarenal extension. This hypoechoic focus measures approximately 4.4 x 2.5 by 7.0 cm and highly suspicious for a renal and perirenal infection given the clinical history. However a malignancy cannot be fully excluded on this ultrasound examination.Bladder: There is echogenic debris in the bladder which is partially mobile when patient's position is changed. There is no significant bladder wall thickening or evidence of emphysematous cystitis.
1.Hypoechoic space-occupying lesion in the left kidney which likely represents intrarenal infection with possible extrarenal extension. However a malignancy cannot be fully excluded on this ultrasound examination. Dedicated cross-sectional renal imaging is recommended to further characterize if clinically warranted.2.Echogenic debris within the bladder.
