Lymphatic drainage of a carcinoma located in the upper fundus of the uterus follows which principal route?

• A Along the round ligament to superficial inguinal nodes
• B Along the infundibulopelvic ligament with the ovarian vessels to para-aortic nodes ✓
• C Along the uterosacral ligaments to presacral nodes
• D Along the cardinal ligament to internal iliac nodes exclusively

Explanation

Tumours of the uterine fundus drain predominantly with the ovarian vessels through the infundibulopelvic ligament to para-aortic lymph nodes, mirroring ovarian lymphatic drainage. Tumours of the lower uterine segment and cervix drain to pelvic nodes such as obturator and iliac groups, and a minor route along the round ligament reaches inguinal nodes. Recognising this dual drainage explains why sentinel node mapping samples both pelvic and para-aortic basins.
