Insights

Follicular lymphoid hyperplasia can mimic intussusception in children, presenting as abdominal pain and enlarged lymph nodes. This condition requires consideration in differential diagnoses for suspected intussusception without significant symptoms.

Area of Science:

  • Pediatric Surgery
  • Gastroenterology
  • Pediatric Radiology

Background:

  • Recurrent abdominal pain in children can stem from various causes, including intussusception.
  • Diagnostic imaging like ultrasound and CT are crucial for identifying intussusception.
  • Abdominal lymphadenopathy can be associated with intussusception.

Observation:

  • A 6-year-old boy presented with recurrent abdominal pain and imaging findings suggestive of ileocecal intussusception.
  • The suspected intussusception showed no morphological changes over a 4-week follow-up.
  • Surgery revealed a cecal tumor instead of intussusception.

Findings:

  • Histopathology after resection confirmed follicular lymphoid hyperplasia, not intussusception.
  • Follicular lymphoid hyperplasia can radiologically mimic intussusception in children.
  • This diagnosis was made in a case initially suspected to be a tumor or lymphoma.

Implications:

  • Follicular lymphoid hyperplasia should be considered in the differential diagnosis of pediatric intussusception, especially with subtle or absent symptoms.
  • Radiologists and surgeons should be aware of this mimicker to avoid unnecessary surgical interventions.
  • Accurate diagnosis through histopathology is essential for appropriate management in pediatric abdominal masses.

Histology of the Small Intestine

The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
