Double ileo-ileal intussusception secondary to inflammatory pseudotumor in an adult: A rare case report

Area of Science:

• Gastroenterology
• Surgical Pathology

Background:

• Adult intussusception is uncommon, typically linked to a lead point.
• Inflammatory pseudotumor is a rare, benign lesion that can act as a lead point in the small bowel.

Observation:

• A 55-year-old woman presented with symptoms of small bowel obstruction.
• Imaging revealed ileo-ileal intussusception, and intraoperatively, a double intussusception was found.
• A lesion at the apex was resected and histopathology confirmed it as an inflammatory pseudotumor.

Findings:

• The patient experienced a double intussusception where one intussuscepted segment served as the lead point for a second.
• Histopathological analysis confirmed the lead point as an inflammatory pseudotumor.
• The patient recovered well after surgical resection and remained asymptomatic.

Implications:

• This case highlights an exceedingly rare cause of acute intestinal obstruction in adults.
• It underscores the importance of considering rare benign tumors as potential lead points in adult intussusception.
• Prompt surgical intervention is crucial for managing such complex cases.
