Insights
A rare omental lipoma was diagnosed in a 2-year-old child presenting with abdominal pain and bloody stools. Surgical resection was successful, with no recurrence observed during a 2-year follow-up period.
Area of Science:
- Pediatric Surgery
- Abdominal Imaging
- Surgical Oncology
Background:
- Omental lipomas are rare benign tumors originating from adipose tissue within the omentum.
- They can present with nonspecific symptoms, often mimicking other intra-abdominal pathologies.
- Early diagnosis and surgical management are crucial for favorable outcomes in pediatric cases.
Observation:
- A 2-year-old female presented with a 5-day history of diarrhea and recent bloody stools.
- Initial physical examination was unremarkable.
- Abdominal ultrasound revealed a large, solid, well-defined mass extending from the right upper quadrant to the left iliac fossa.
Findings:
- Magnetic resonance imaging confirmed the mass as an omental lipoma, displacing adjacent abdominal structures.
- Surgical resection was performed laparoscopically one week after diagnosis.
- Histopathological examination confirmed the benign nature of the lipoma.
Implications:
- This case highlights the importance of advanced imaging in diagnosing rare pediatric abdominal masses.
- Laparoscopic resection is a feasible and effective treatment for omental lipomas.
- Long-term follow-up confirmed the absence of tumor recurrence, underscoring successful surgical management.
Abstract:
A 2-year-old female patient, admitted in the emergency room, presented diarrhea for 5 days and bloody stools in the last 24 hours. Physical examination revealed no significant findings. Ultrasound was initially performed, showing an elongated, well delimited and solid mass occupying since right hypocondrium until left iliac fossa, displacing adjacent structures. In sequence, magnetic resonance imaging was performed for confirmation of findings suggestive of omentum lipoma. After 1 week, the surgical resection was performed by videolaparoscopic acess. During 2-year follow-up, there was no sign of recurrence.
