Learning objectives To recognize the imaging findings of intussusception, differentiate its types and discuss the indications for reduction using ultrasound- or fluoroscopy-guided techniques.
Read more Background Intussusception is the invagination of one proximal segment of the intestine into an adjacent distal segment and represents a common pediatric emergency, requiring radiological expertise for both diagnosis and treatment [1]. It is a leading cause of acute abdomen in children aged 3 months to 3 years, although it can occur at any age. In pediatric patients, intussusception is primarily associated with hypertrophic lymphoid tissue post-infection and in most cases a lead point is not identified [2].The classic clinical triad...
Read more Findings and procedure details Diagnosis:Ultrasonography is the modality of choice for diagnosing intussusception, featuring high sensitivity and specificity (92–100%), no radiation exposure, easy accessibility and patient comfort [2, 4]. Distinctive intussusception ultrasound sings include [3]: the “target”, “doughnut” or “multiple concentric ring” sign on axial scans, formed by concentric alternating echogenic and hypoechoic bands. The echogenic bands consist of the serosa and submucosa on either side of the hypoechoic muscularis propria. [fig 1] the “pseudokidney” sign on longitudinal scans, where the mesentery, containing fat and blood vessels...
Read more Conclusion Prompt diagnosis and treatment of intussusception are essential to prevent complications such as bowel necrosis. Ultrasound is the preferred imaging modality, offering high sensitivity and a radiation-free approach. Both fluoroscopy-guided pneumatic enema and ultrasound-guided hydrostatic enema are safe and effective methods for noninvasive reduction of ileocolic intussusception. The absence of ionizing radiation in the ultrasound-guided hydrostatic enema makes it a preferable option for pediatric intussusception reduction, provided that appropriate staffing and radiologist expertise are available.
