Abstract:
The Meckel's diverticulum is the commonest congenital anomaly of the gastrointestinal tract, often presenting with complications such as gastrointestinal bleeding, intussusception, bowel obstruction and diverticulitis, which are often misdiagnosed. Imaging plays an important role in the early diagnosis and characterization of these conditions and is very helpful in decision making. The Meckel's diverticulum and its complications have myriad presentations and appearances on various imaging modalities. Thus, sound knowledge of the anatomy, embryology, clinical presentation, imaging characteristics and complications is crucial to the practice of abdominal imaging. We present a review of the literature and current radiological practices in the diagnosis and management of the Meckel's diverticulum and its various complications with special emphasis on the imaging of various complications, mimickers and pathological correlation.
Insights
Meckel's diverticulum, a common congenital anomaly, frequently causes complications like bleeding and obstruction, often missed by doctors. Advanced imaging is crucial for accurate diagnosis and management of this condition.
Area of Science:
- Gastroenterology
- Radiology
- Pediatric Surgery
Background:
- Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract.
- Complications include gastrointestinal bleeding, intussusception, bowel obstruction, and diverticulitis, frequently leading to misdiagnosis.
- Imaging is vital for early diagnosis, characterization, and treatment decisions.
Purpose of the Study:
- To review the literature and current radiological practices for diagnosing and managing Meckel's diverticulum and its complications.
- To emphasize the imaging characteristics of various complications, their mimickers, and pathological correlations.
Main Methods:
- Literature review of Meckel's diverticulum diagnosis and management.
- Analysis of current radiological practices and imaging modalities.
- Emphasis on imaging features of complications and differential diagnoses.
Main Results:
- Meckel's diverticulum presents with diverse imaging findings across modalities.
- Accurate diagnosis relies on understanding anatomy, embryology, and clinical presentations.
- Imaging aids in differentiating complications from mimickers.
Conclusions:
- Comprehensive knowledge of Meckel's diverticulum and its complications is essential for abdominal imaging specialists.
- Radiological assessment is critical for timely and accurate diagnosis and management.
- Understanding imaging nuances improves patient outcomes by reducing misdiagnosis.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
