    Abstract:
    When resecting small tumors or tumors with an irregular margin, a marking technique is conducted prior to the surgery. CT-guided marking techniques are common in pulmonary surgery, but it is rarely used in abdominal or urological surgery. We performed a marking technique for a small tumor that was undetectable by ultrasound using CT guidance prior to laparoscopic resection.A 63 year-old woman, two years after total hysterectomy for uterine stromal sarcoma, underwent combined right kidney resection and retroperitoneal tumor resection for a giant recurrence. Two months after the surgery, micro recurrence was observed in the vicinity of the right intestinal psoas muscle which upon follow up, the tumor size increased to 1 cm. Surgical resection of the small recurrent tumor was planned. Since it was difficult to detect by ultrasound, preoperative CT-guided marking was performed. Retroperitoneal laparoscopic resection was performed the following day. The histopathological diagnosis was endometrial stromal sarcoma.
