Figure 3. — A female receiving immunomodulating therapy for inflammatory bowel disease was admitted with a fever and diagnosed with a urinary tract infection. (a) Sagittal ultrasound (US) image of the right kidney shows diffuse multifocal regions of hypoechogenicity (arrows). (b) Transverse power Doppler US image demonstrates no flow in one of the hypoechoic regions at the mid-pole level (arrows). (c) Coronal contrast-enhanced CT image better delineates multifocal cystic masses/abscesses throughout the right kidney with associated renal swelling. Klebsiella infection with multifocal renal abscess was confirmed by aspiration prior to drain placement.
