摘　　要：BACKGROUND Primary retroperitoneal liposarcoma(PRPLS)is a rare soft tissue tumor with nonspecific clinical symptoms;it has different computed tomography(CT)image features according to pathological types.Some patients with a single tumor have been previously reported in the literature.We present an exceptional case of a PRPLS patient with multiple large tumors exhibiting different patterns of appearance on CT and confirmed as atypical lipomatous tumor/welldifferentiated liposarcoma by postoperative pathology.CASE SUMMARY A 64-year-old man presented with abdominal distension for 1 year.The patient was diagnosed with PRPLS based on physical examination,laparotomy,ultrasonography,CT scan,and surgery.Both of the tumors were completely resected through surgery and confirmed as atypical lipomatous tumor/welldifferentiated liposarcoma by postoperative pathology.The postoperative course was uneventful without recurrence or metastasis,as demonstrated by abdominalpelvic CT during an 18 mo follow-up.CONCLUSION Multiple large Well-differentiated liposarcomas with different patterns of appearance on CT image can occur simultaneously in the same patient,to which more attention should be paid to make an effective differential diagnosis.
