Radiological insights into diverticulitis: Clinical manifestations, complications, and differential diagnosis

Area of Science:

• Gastroenterology
• Radiology
• Emergency Medicine

Background:

• Diverticulitis involves infection of intestinal diverticula, presenting with pain and inflammation.
• Accurate diagnosis is crucial, especially in acute phases where endoscopy is contraindicated due to perforation risk.

Purpose of the Study:

• To review the radiological findings in diverticulitis.
• To emphasize the role of computed tomography (CT) in diagnosis, staging, and complication management.

Main Methods:

• Review of radiological findings in diverticulitis.
• Focus on computed tomography (CT) imaging characteristics.
• Discussion of the Sartelli classification system.

Main Results:

• CT is critical for diagnosing diverticulitis and differentiating it from other conditions.
• The Sartelli classification provides a standardized imaging-based staging system.
• Imaging identifies complications like abscesses and peritonitis.

Conclusions:

• Radiological imaging, particularly CT, is essential for diagnosing and managing diverticulitis.
• The Sartelli classification enhances the understanding and communication of diverticulitis severity.
• Imaging aids in distinguishing diverticulitis from mimics and guiding treatment.
