Summary
A rare amebic abscess in the lesser omentum was identified without initial signs of liver involvement. This case highlights the need for early diagnosis of hepatic amebiasis, even when liver abscesses are not apparent.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Surgical Pathology
Background:
- Amebic abscesses typically occur in the liver, but extrahepatic manifestations are possible.
- The lesser omentum is an uncommon site for amebic abscess formation.
- Distinguishing amebic abscesses from other intra-abdominal pathologies can be challenging.
Observation:
- A case report details an amebic abscess confined to the lesser omentum.
- Imaging and operative findings initially showed no evidence of a concurrent liver abscess.
- The clinical presentation suggested a possible prior rupture of a liver abscess into the abdominal cavity.
Findings:
- The amebic abscess was successfully localized and treated.
- Histopathological examination confirmed the presence of Entamoeba histolytica.
- The absence of a detectable liver abscess at presentation underscores the diagnostic complexity.
Implications:
- This case emphasizes the importance of considering amebic etiology in unexplained intra-abdominal abscesses near the liver.
- Prompt diagnosis and treatment are crucial to prevent complications and improve patient outcomes.
- Further research into the pathogenesis of extrahepatic amebic abscesses is warranted.
