Insights
Retroperitoneal abscesses in infants may stem from omphalitis (inflammation of the navel). Early suspicion and treatment are crucial for favorable outcomes in these rare cases.
Area of Science:
- Pediatric surgery
- Neonatal infections
- Abdominal abscesses
Background:
- Retroperitoneal abscesses in infants are uncommon and often idiopathic.
- Omphalitis is a potential, yet under-recognized, contributing factor.
Purpose of the Study:
- To investigate the aetiopathogenetic factors of retroperitoneal abscess in neonates.
- To explore the correlation between omphalitis and retroperitoneal abscess development.
Main Methods:
- Case report of two infants with retroperitoneal abscess.
- History of omphalitis in the neonatal period.
- Surgical drainage and microbiological cultures.
Main Results:
- Staphylococcus aureus identified in one case's abscess and the other's umbilical pus and abscess.
- Both infants recovered well following surgical intervention.
- Omphalitis was a preceding factor in both cases.
Conclusions:
- Omphalitis may be an aetiopathogenetic factor in neonatal retroperitoneal abscess.
- Early diagnosis and prompt surgical treatment are vital.
- Further investigation into the omphalitis-abscess link is warranted.
Aim:
To evaluate the aetiopathogenetic factors in cases of retroperitoneal abscess in young infants, particularly the correlation with omphalitis.
Methods:
We describe the cases of two infants, aged 8 and 3 wk, respectively, with a history of omphalitis during the first weeks of life and subsequent development of a retroperitoneal abscess. Both infants underwent surgical drainage of the abscess.
Results:
In case 1, Staphylococcus aureus was found in cultures from abscess pus, and in case 2 from umbilical pus, abscess purulent material and blood. Both infants are in good health after a follow-up of 6 mo and 8 y, respectively.
Conclusion:
Retroperitoneal abscesses in young infants are usually considered to be idiopathic. A correlation with omphalitis was found in both of the reported cases and it is thought that this could have been due to an aetiopathogenetic factor. Furthermore, we stress the importance of suspicion of retroperitoneal abscesses for early diagnosis and treatment, and discuss the therapeutic strategies.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
