急性腸繫膜淋巴腺炎通常為一自限性之臨床情況，但是兒童發生腹內膜瘖則是相當危急。過去，在兒童曾經報導過腸繫膜淋巴腺炎可能是造成腹內膜瘖的潛在病因，但病例極為少數。本文報告一10歲男孩，起初診斷為急性腸繫膜淋巴腺炎，但併發腹部急症。

Acute mesenteric lymphadenitis is usually a self-limiting clinical condition but intra-peritoneal abscesses are critical in children. It has been reported but was so rarely that mesenteric lymphadenitis could be an underlying etiology of intra-peritoneal abscess in children. We report a 10 year-old boy that presented with acute mesenteric lymphadenitis initially, but complicated with acute abdomen.
