Arrowheads in the 1st to 4th columns show the obturator lymph nodes, common iliac lymph nodes, para-aortic lymph node #1, and para-aortic lymph node #2, respectively.
At 1.5 months after the surgery, CT revealed no recurrence to the obturator lymph node (Figure 1(i)), but the remaining commoniliacLN enlarged to 22.2[+ or -]0.8mm (Figure 1(j)).
In this case, the recurrent tumor involved the external iliac artery, external iliac vein, right
obturator lymph nodes, and the small intestine.
Notably, lymphatic drainage of uterine lesions confined to the corpus is primarily to the external iliac and the
obturator lymph nodes [8].
During pelvic lymphadenectomy, surgeons generally sample the lower external iliac and
obturator lymph nodes.
During pelvic lymphadenectomy, surgeons generally sample the lower external iliac and
obturator lymph nodes. A study showed that when the dissection was extended to the higher external, internal, and common iliac lymph nodes as well as the presacral lymph nodes, the rate of metastasis increased from 10% to 26% (J.
