Focal pyelonephritis

Case contributed by: Dr Jeremy Jones

Presentation:

Recent symptoms of UTI. Pyrexia. WBC in urine.

Patient Data:

Age: 7
Gender: Female
Race: Caucasian
Modality: Ultrasound

In the interpolar region of the right kidney is an ovoid heterogeneous avascular mass. With the features of sepsis and infection, features here are most in keeping with focal pyelonephritis.

Case Discussion:

Features of focal pyelonephritis. There is no collection, so this is not an abscess.

While other differentials may be considered, the presentation with sepsis and appropriate urinalysis makes infection the most likely diagnosis. Complete resolution at 6 months was confirmed on ultrasound.
