Omental Cyst Presenting as an Acute Abdomen in a Pediatric Patient: A Case Report.

Background: Omental cysts are the rarest forms of intra-abdominal cystic lesions. They are usually asymptomatic but can also present as acute abdomen. The presentation is confusing in some cases, which may result in mismanagement, added costs, and trouble for the patient. A pre-operative diagnosis is challenging, especially in resource-limited settings, and requires a high level of suspicion and a cautious approach during emergency exploratory laparotomy to avoid complications.

Case Details: This is a 4 year old male child who presented with high grade fever, vomiting, and abdominal pain of 2 days duration. He was tachypneic, tachycardic, and had diffuse abdominal tenderness. Emergency laparotomy revealed a large cyst with hemorrhagic content. Complete removal of the cyst was done, and the patient was discharged after improvement on the third post-operative day.

Conclusion: Omental cysts are rare in children and have varieties of presentations. Even though preoperative diagnosis is challenging, esspecially in resource-limited settings, clinicians should consider omental cysts in a child presenting with an acute abdomen. It is important for surgeons to consider omental cysts when carrying out emergency laparotomy for an unidentified abdominal condition.
