Mesentery lymphadenitis is an inflammation of the lymph nodes in the membrane (mesentery) that connects the colon or bowel to the abdominal wall. It is often mimicked by appendicitis, but is rarely dangerous. 150 consecutive paediatric patients were recommended for abdominal sonography for a variety of reasons. Any lymph node greater than 5 mm found was recorded. The age of the patient, the diagnosis, the presence of clusters, the presence of enlarged abdominal lymph nodes, their position, size, and quantity were all noted. Acute appendicitis, intussusception, and ovarian torsion are the three main clinical concerns. Mesenteric adenitis is an inflammation of the mesenteric lymph nodes caused by Yersinia, Staphylococcus, Salmonella, other mycobacterium, and viruses. It is believed that the clinical condition of mesenteric adenitis mimics an "acute abdomen". A total of 260 patients were investigated in a study, with the most common complaints being abdominal discomfort, excessive weeping, fever, dysuria, vomiting, and others. 76 patients had swollen lymph nodes, of whom 73 (35.6%) were from paediatric emergency and 3 (5.5%) were from opd. The prevalence of enlarged mesenteric lymph nodes in symptomatic children was significantly greater than in asymptomatic children. Children under the age of 10 are more likely to have larger MLNs, and those with abdominal pain as their main complaint are more likely to have swollen lymph nodes. Mesenteric lymphadenitis is the most frequent diagnosis, with right iliac fossa lymph nodes being enlarged in the majority of patients. This study found that swollen lymph nodes are more common in children who have a history of abdominal pain. Younger children are more likely to have swollen lymph nodes, and intussusception is more common in larger lymph nodes. Sonography can help establish a primary diagnosis and distinguish between medical and surgical crises
