다국어 초록 (Multilingual Abstract)

Background: For the treatment of metastatic lesions in recurrent cervical cancer, surgical resection is attempted in order to reduce tumor burden and increase response to chemotherapy and radiotherapy. However, surgical resection is not easy due to the irregular pattern of metastasis and metastasis to places that are hard to access. We need more anatomical information about the metastatic lesions to achieve a clear surgical resection.
Case Presentation: We report a case of salvage lymphadenectomy for an isolated metastatic lesion in the para-aortic lymph node in a 53-year old woman with a history of cervical cancer initially treated by radical hysterectomy. Preoperative 3 dimensional CT angiography showed the huge retrocrural metastatic lymph node with clear visualization and demarcation of the lesion. A more than 10 cm sized metastatic lesion was located behind the vena cava, aorta and left kidney encompassing the left renal artery and lumbar arteries. The metastatic lymph node was excised clearly with left nephrectomy. On histologic examination, the tumor invaded into the renal pelvis of the left kidney. Conclusion: Compared with conventional imaging techniques, 3 dimensional CT angiography can more clearly visualize the lesions. Three dimensional CT angiography provides a useful anatomical information such as the exact size and location with clear visualization and demarcation.
