Meckel's diverticulum (MD) is the most common congenital anomaly of the gastro-intestinal tract (approximately 2% of population), and arises from improper closure and absorption of the omphalomesenteric duct. Very few cases of Meckel's diverticulitis on the mesenteric side have been reported in the surgical literature, and no reported cases have been documented on preoperative imaging. We report a 65-year-old woman presenting symptoms and signs of acute abdomen with an initial suspicion of acute appendicitis. MDCT imaging revealed a mesenteric abscess in the right lower quadrant at the level of the distal ileum as a complication of Meckel's diverticulitis on the mesenteric side. The patient recovered after a diverticulectomy without the need for a small bowel resection. This case demonstrates that MDCT is a fast imaging technique that may be helpful in the emergency setting for the preoperative diagnosis of an unusual complicated MD on the mesenteric side.
梅克尔憩室（MD）是胃肠道最常见的先天性异常（约占人口的2%），由卵黄管的异常闭合和吸收引起。外科文献中报道的肠系膜侧梅克尔憩室炎病例极少，术前影像学检查也未见相关报道。我们报告一例65岁女性，表现为急腹症的症状和体征，最初怀疑为急性阑尾炎。MDCT成像显示在回肠末端水平的右下腹有一个肠系膜脓肿，是肠系膜侧梅克尔憩室炎的并发症。患者在憩室切除术后康复，无需进行小肠切除术。该病例表明，MDCT是一种快速成像技术，在急诊情况下可能有助于术前诊断肠系膜侧不常见的复杂梅克尔憩室。
