Radiologic images.. (a) Coronal view from computed tomography angiography demonstrates multiple solid masses fed by a branch of gastroduodenal artery (dotted circle) and the ileal branch of the superior mesenteric artery (solid circle).. (b) Celiac angiography detected a branch of gastroduodenal artery (dotted circle).. (c) Superior mesenteric artery angiography showed the ileal branch (solid circle).

CT angiography detected tumors fed by omental and mesenteric arteries (Fig. 1). Considering the possibility of malignant tumors, we performed an ultrasound (US)-guided needle biopsy and revealed the presence of leiomyoma.
Intraoperative image.. A large tumor arising from the mesentery of the small intestine was removed by ligating the feeding vessels without intestinal resection.

All the 19 tumors arising from the omentum and mesenterium and weighing 7647 g in total (including four tumors weighing 3052 g, 2118 g, 1120 g, and 786 g, respectively) were removed without injuring other organs because of non-invasive tumor development (Fig. 2).
Histopathological findings of resected specimens.. (a) Macroscopic appearance of the largest tumor: the tumor measured 34 x 24 cm, with a smooth surface.. (b) Microscopic examination showed a typical leiomyoma without malignancy (Hematoxylin-eosin staining, 200x).

The maximum diameter of the largest tumor was 34 cm (Fig. 3). The pathological diagnosis was nonmalignant LPD with leiomyoma (Fig. 3).
