Summary
Acute lobar nephronia, a localized kidney infection, presents as a renal mass. Prompt antibiotic treatment can lead to complete resolution, confirming the diagnosis.
Area of Science:
- Nephrology
- Radiology
- Infectious Diseases
Background:
- Acute lobar nephronia is an uncommon localized renal infection.
- Distinguishing it from other renal masses like abscesses, infected cysts, or renal carcinoma is crucial.
Observation:
- A patient presented with pyelonephritis symptoms and a renal mass on ultrasound.
- CT revealed a mass with peripheral enhancement and central striation, consistent with infection.
Findings:
- Antibiotic treatment was initiated for suspected acute lobar nephronia.
- Follow-up imaging demonstrated complete resolution of the renal mass.
Implications:
- Acute lobar nephronia should be considered in patients with renal masses during urinary infections.
- Clinical-radiological correlation and therapeutic response confirm the diagnosis.
