Abstract: Objective: To analyze the clinical data and surgical treatment procedures of a patient with rare huge serous cystadenoma of broad ligament,to clarify its diagnostic and treatment characteristics,and to explore the present situation and advantages of laparoscope in the operation of broad ligament tumor. Methods: The patient was admitted to hospital due to abdominal distension for 2 years and aggravated illness for 2 months.The diagnosis result was pelvic and abdominal mass arising from ovarian according to the preoperative color Doppler ultrasound and physical examination.Based on the laparotomy and intraoperative rapid pathological results,the patient was diagnosed as huge serous cystadenoma of broad ligament.The location of ureter and uteri artery and vein were carefully identified during the operation and they were ligated for hemostasis at the basal part of tumor.The operation was successful. Results: The ultrasonography image of the huge serous cystadenoma of broad ligament was very similar to that of large ovarian tumor.The misdiagnosis rate of ultrasound was high,and CT and MRI were important for the identification of large broad ligament tumor;the accuracy rate of preoperative diagnosis could be improved by CT and MRI.Carefully blunt separation close to the tumor surface during the operation could avoid the ureteral injury.The patient recovered well and discharged from hospital. Conclusion: The symptoms of huge serous cystadenoma of broad ligament patient are lack of specificity.The accuracy rate of preoperative diagnosis should be improved in combination with the medical history and imageological findings of the patient.The operation plan should be chosen reasonably and the operation should be carefully performed to avoid the occurrence of secondary injuries.
