Insights
Mesenteric lymphadenopathy is common in children with recurrent abdominal pain, often being the sole abnormal finding on ultrasound (US). This study assessed its prevalence in pediatric patients undergoing abdominal US.
Area of Science:
- Pediatric Radiology
- Gastroenterology
Background:
- Recurrent abdominal pain is a common pediatric complaint.
- Ultrasound (US) is frequently used to evaluate for organic causes of abdominal pain in children.
Purpose of the Study:
- To determine the prevalence of mesenteric lymphadenopathy in children experiencing recurrent abdominal pain.
- To compare US findings in children with recurrent abdominal pain to a healthy control group.
Main Methods:
- A prospective study involving 189 children with recurrent abdominal pain and 73 controls.
- Abdominal US with graded compression was performed, noting lymph node characteristics and location.
- Patients were followed for up to one year, with repeat US in a subset.
Main Results:
- Mesenteric lymphadenopathy was identified in 61.4% of children with recurrent abdominal pain, significantly higher than the 9.6% in controls (P<0.001).
- The prevalence was higher in younger boys, with nodes predominantly in the right lower quadrant.
- Additional abnormal US findings were noted in 14.2% of the study group versus 6.8% in controls.
Conclusions:
- Mesenteric lymphadenopathy is a frequent finding on abdominal US in children with recurrent abdominal pain.
- It is often the only abnormal sonographic finding, highlighting its significance in this population.
Background:
Children with recurrent abdominal pain often undergo US to confirm or exclude organic disease.
Objective:
To assess the prevalence of mesenteric lymphadenopathy on US in these children.
Materials And Methods:
We prospectively studied 189 children with recurrent abdominal pain with US of the abdomen, using graded compression. The results were compared with 73 children in a control group. The children in both groups were divided into three age groups. The size, number, morphology and location of mesenteric lymph nodes were noted, as well as additional findings. Pediatricians followed the patients from 3 months to 1 year, and a repeat US study was done in 30 children.
Results:
Mesenteric lymphadenopathy was present in 116 of 189 children (61.4%), with the greatest prevalence in boys in the younger age groups. The location of the nodes was mainly in the right lower quadrant. In the control group, 7 of 73 children had mesenteric lymphadenopathy, a significantly lower prevalence than in the study group ( P<0.001). Additional findings, apart from lymphadenopathy, were present in 27 (14.2%) of the 189 children in the study group, and in 5 (6.8%) of the 73 children in the control group.
Conclusion:
Mesenteric lymphadenopathy is a common, and often the only abnormal, finding on US in children with recurrent abdominal pain.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
