Summary
A solid mass in a renal transplant graft, initially suspected as malignancy, was diagnosed as lobar nephronia. Prompt antibiotic treatment led to the mass resolution, highlighting the importance of considering this condition in transplant patients.
Area of Science:
- Nephrology
- Infectious Diseases
- Radiology
Background:
- Renal transplantation is a life-saving procedure for end-stage renal disease.
- Post-transplant complications can include infections and masses, requiring accurate diagnosis.
- Solid renal masses in transplant recipients pose diagnostic challenges, with malignancy being a primary concern.
Observation:
- A patient presented with a solid renal graft mass 15 years post-transplantation.
- Initial ultrasound findings were equivocal, suggesting malignancy or focal acute bacterial nephritis (lobar nephronia).
Findings:
- Renal biopsy confirmed lobar nephronia, characterized by significant inflammatory infiltrate and pus formation.
- Antibiotic therapy resulted in the complete resolution of the renal mass.
Implications:
- Lobar nephronia should be considered in the differential diagnosis of solid renal masses in kidney transplant recipients.
- Renal ultrasonography is crucial for identifying potential lobar nephronia.
- Timely antibiotic treatment can effectively manage lobar nephronia, preventing unnecessary interventions.
