Renal abscess in infancy

Area of Science:

• Pediatric Nephrology
• Pediatric Surgery
• Medical Imaging

Background:

• Renal abscesses are uncommon in infants, posing diagnostic challenges.
• Differentiating renal abscess from infected renal cysts can be difficult, particularly with perinephric involvement.

Observation:

• A case report of an infant presenting with a left lumbocostal mass.
• The mass was initially suspected to be a tumor.

Findings:

• The mass was diagnosed as a renal abscess.
• This represents a previously undocumented presentation of infantile renal abscess.

Implications:

• Highlights the importance of considering renal abscess in the differential diagnosis of infantile abdominal masses.
• Emphasizes the need for advanced imaging techniques for accurate diagnosis.
• Suggests atypical presentations of common pediatric conditions should be recognized.
