Report of one case: surgical treatment for neuroendocrine tumors.

A 68-year-old female patient was admitted to our center due to anorexia and epigastric pain for 2 months. Plain abdominal CT revealed a splenic space-occupying lesion; it had invaded the greater curvature of stomach and had blurred margin with the tail of pancreas. The longest diameter was about 10.7 cm. The lesion was considered to be malignant, accompanied with peritoneal nodules; the possibility of lymph node metastasis could not be ruled out. MRI revealed that the mass was located in front of the spleen, with irregular shape and unclear margin. Part of the mass invaded the greater curvature of stomach and part of it had blurred margin with the tail of pancreas. The largest cross section sized 9.4 cm × 6.9 cm. It showed intermediate and high signals on T2WI/FS, which corresponded to restricted diffusion on DWI sequences. The levels of tumor markers including CA19-9, CA242, and CEA were normal. Exploratory laparotomy + resection of the body and tail of pancreas + resection of part of stomach wall + removal of nodules on liver surface were performed. Postoperative pathology confirmed that the lesion was a neuroendocrine tumor (G1).
