Conclusion
Although scintigraphy is highly accurate for the diagnosis of symptomatic Meckel’s diverticulum in children,
ultrasound can be helpful in patients in whom nuclear medicine studies have been negative.
Knowledge of common and uncommon sonographic features of complicated Meckel’s diverticulum and its differential diagnosis can aid in early and appropriate diagnosis,
without the need of further radiological examinations that may imply ionizing radiation or sedation/anaesthesia.
To summarize the presence of the following US findings should make us think of a complicated Meckel’s diverticulum:
- A normally appearing appendix
- Focal increased echogenicity,
hyperemia and stranding of mesenteric fat at the right lower quadrant or periumbilical regions
- A blind ending structure with gut signature in continuity with distal ileum,
with or without inflammatory local changes
- A blind ending structure with focal inflammatory phenomena measuring more than 25mm in diameter
- A complex intussusception with an echogenic mass with a layered appearance in the middle of intussusceptum.
