Adult intussusception is rare, often caused by a lead point. This review highlights various causes and their imaging findings, crucial for diagnosis and treatment planning.
Area of Science:
- Gastroenterology
- Radiology
- Abdominal Imaging
Background:
- Adult intussusception (AI) is an uncommon condition, distinct from pediatric cases.
- A significant majority of AI cases (70-90%) involve an underlying organic lesion, often termed a 'lead point'.
- Classification of intussusception considers location, cause, and the presence of a lead point.
Purpose of the Study:
- To review and illustrate the diverse etiologies of adult intussusception.
- To present characteristic radiological and endoscopic findings associated with various causes of AI.
- To emphasize the critical role of imaging in diagnosing AI and guiding treatment.
Main Methods:
- Review of institutional cases of adult intussusception.
- Analysis of imaging findings across multiple modalities: plain radiography, ultrasonography, computed tomography (CT), and magnetic resonance (MR) imaging.
- Inclusion of endoscopic findings where applicable.
Main Results:
- AI is frequently associated with a lead point, necessitating thorough investigation.
- A wide spectrum of organic lesions can cause AI, presenting with distinct imaging features.
- Radiological modalities effectively demonstrate the intussusception and associated pathology.
- Endoscopy provides complementary diagnostic information for certain AI etiologies.
Conclusions:
- Imaging is paramount for the diagnosis of adult intussusception.
- Identifying the underlying cause, particularly a lead point, is essential for effective management.
- A multimodal imaging approach enhances diagnostic accuracy for AI.
