Abstract

Objective: To investigate clinical value of high frequency ultrasonography in the diagnosis of mesenteric lymphadenitis. Methods: The children’s abdomen were carefully scanned by using Toshiba Aplio 500 high frequency ultrasound(5~12 MHz), special attention was paid to the umbilical area and the right lower abdomen. The number, size, shape and internal echo of the mesenteric nodes were observed and recorded, meanwhile also observed whether there were other abdominal abnormalities. The longitudinal diameter of the lymph nodes above 0.5 cm was considered enlarged. Results: In 130 children with acute abdominal pain, the demonstration rate of lymphadenitis was 100%. Enlarged lymph nodes were located in the right lower quadrant or in the navel area. In 124 cases(95.4%) the number of enlarged lymph nodes more than 5. In 50 cases a second ultrasound examination were performed after two weeks, the mesenteric lymph nodes showed no change in 30 cases, size of the enlarged nodes reduced in 20 cases. Conclusion: High frequency ultrasound not only can display the pediatric mesenteric lymph node clearly, but also can provide reliable evidence for clinical diagnosis and differential diagnosis of mesenteric lymphadenitis.
