Meckel's diverticulum Imaging: In and Out

Area of Science:

• Gastroenterology
• Pediatric Surgery
• Radiology

Background:

• Meckel's diverticulum (MD) is the most frequent congenital anomaly of the omphalomesenteric duct, occurring in 2-3% of the population.
• It's a true diverticulum of the ileum, often containing heterotopic gastric or pancreatic mucosa, increasing risks of bleeding and inflammation.
• Complications vary by age and sex, including hemorrhage, obstruction, and ischemia.

Purpose of the Study:

• To review the spectrum of Meckel's diverticulum complications.
• To discuss the embryological basis of MD.
• To highlight the role of imaging in diagnosis and current management guidelines for incidentally found MD.

Main Methods:

• This is a pictorial essay.
• Review of imaging modalities including Ultrasound (USG), CT, and Nuclear Medicine.
• Discussion of embryological concepts and management guidelines.

Main Results:

• Meckel's diverticulum presents with diverse complications, with imaging playing a critical diagnostic role.
• Imaging modalities like USG, CT, and Nuclear Medicine are essential for identifying MD-related issues.
• Management strategies for incidentally detected MD are also addressed.

Conclusions:

• Accurate diagnosis of Meckel's diverticulum complications relies heavily on appropriate imaging.
• Understanding the embryology and spectrum of complications is key for effective patient management.
• Current guidelines provide a framework for managing incidentally discovered Meckel's diverticulum.
