(A), Computed tomography (CT) scan shows an elliptical, very low-density mass in the left middle abdomen, which is wrapped in the left abdominal cavity, and the surrounding intestine is slightly compressed and displaced. (B), The tumor was not enhanced on enhanced CT scan, and its blood supply arteries were not shown.

Intra-abdominal lipoma should be considered, and the blood-supplying vessels were derived from branches of the omental artery (Figures 1A,B).
(A), Laparoscopic examination of the left mid-upper abdominal tumor, which was yellow, solid, isolated, derived from the greater omentum, without torsion. (B,C), Ultrasonic knife separates the omentum and the tumor. (D), Ultrasonic scalpel coagulates the tumor blood supply artery.

It was yellow, solid, soft, isolated, and its base was derived from the greater omentum without torsion (Figure 2A). No other abnormality was found in the abdominal cavity below the umbilicus to take out the tumor tissue completely (Figures 2B-D).
(A), A piece of yellow tissue can be seen with the naked eye, 295g in weight, about 80mm* 55mm * 30mm in size, with intact capsule, solid and soft. (B), Microscopically, the tumor is composed of mature adipocytes without atypia.

The weight of the excised tumor tissue was 295 g, size of about 80 x55 x30 mm with; the tumor capsule intact; and the cut surface is grayish-yellow and soft (Figure 3A). Microscopic examination showed that the tumor was composed of mature adipocytes without atypia (Figure 3B); and the diagnosis was of a benign omental lipoma.
