A 70-year-old man presenting with acute abdominal pain was admitted to our hospital for further examination. Abdominal computed tomography (CT) showed a multilobulated cystic lesion measuring about 7 cm in diameter in the right lower abdomen. Two days later, the pain disappeared spontaneously. Computed magnetic resonance imaging showed a mass in the middle of the lower abdomen which was visualized as a high signal intensity on T2-weighted images. The findings led to the strong suspicion of a jejunal lymphangioma. We planned elective surgery, but the patient was admitted again a week later for the same type of abdominal pain. Abdominal CT showed a mass in the left lower abdomen. Although the pain again disappeared a day later, emergency surgery was performed, considering the risk of recurrence of the abdominal pain in the short term and of intestinal ischemia or necrosis because of exacerbation of intestinal torsion. Intraoperatively, a yellowish-white soft multilobulated cystic tumor was found in the mesentery of the jejunum, adhering tightly to the jejunal wall. Therefore, tumor removal with partial resection of the jejunum was performed. The histopathological diagnosis was jejunal mesenteric lymphangioma. Until follow-up 3 years after surgery, he remained free of relapse.
