Usefulness and limitation of ultrasound for children with Peutz–Jeghers syndrome: A case series.

This article focuses on the diagnostic utility of ultrasound in evaluating pediatric patients with Peutz–Jeghers syndrome (PJS), a rare condition characterized by hamartomatous polyposis throughout the gastrointestinal tract. In a case series of five pediatric patients, ultrasound failed to detect polyps in asymptomatic individuals, even when polyps exceeded 10 mm, but was effective in identifying intussusception in symptomatic patients presenting with abdominal pain. The study highlights that while ultrasound has limitations in visualizing hamartomatous polyps due to their size, location, and tissue characteristics, it remains a valuable, noninvasive first-line tool for detecting complications such as intussusception in PJS patients. Understanding these diagnostic strengths and limitations can assist clinicians in managing and monitoring PJS.
