Summary

Computed tomography (CT) reveals a characteristic target sign in various types of intestinal intussusception. CT imaging aids in diagnosing intussusception and identifying its underlying causes.

Area of Science:

  • Radiology
  • Gastroenterology
  • Abdominal Imaging

Background:

  • Intussusception, a condition where one part of the intestine slides into another, can occur at various locations and have diverse etiologies.
  • Accurate diagnosis and identification of the underlying cause are crucial for effective management.
  • Conventional imaging modalities like ultrasound and contrast studies have limitations in fully characterizing intussusception.

Observation:

  • This study details the typical computed tomography (CT) findings associated with intestinal intussusception.
  • A consistent 'target sign' is observed across different types of intussusception, including Meckel's diverticulum, idiopathic ileocolic intussusception in infants, and post-polypectomy colorectal intussusception.
  • CT demonstrates superior diagnostic capability compared to conventional methods.

Findings:

  • Computed tomography (CT) provides a characteristic 'target sign' in intestinal intussusception.
  • CT enables unequivocal diagnosis of intussusception, regardless of its origin or location.
  • CT frequently identifies or excludes the underlying pathologies triggering the intussusception.

Implications:

  • CT imaging is a valuable tool for diagnosing intestinal intussusception and elucidating its etiology.
  • The 'target sign' on CT is a reliable indicator across various intussusception scenarios.
  • Enhanced diagnostic accuracy with CT can guide appropriate clinical management and surgical planning.
