[|Human|] where is the periceliac and peri-sma lymphadenopathy? and retroperitoneal lymphadenopathy,  where is the left paracolic gutter.   I have ovarian cancer and these are new areas on my ct scan.  I am having pian in my lower back and wonder if they are in that area.
[|AI|]  Hello, It is important to know if you have been operated for ovary cancer, or if you still have the tumor, and it is a large one. In most cases, patients with a tumor in the ovary can have pinching of nerves or nerve irritation that can cause the perception of pain. Since the nerves supplying the area originate in the lower back, these nerves make you feel that the pain is in the lower back. Any post-operative changes in the pelvis if applicable might also cause such a pain in the lower back. Another important, but the rare possibility is if you have any condition in the bones of the lower back which might be causing the pain. It is possible that cancer might have infiltrated certain structures, and therefore causing pain in the lower back. Please discuss this with your doctor and get further investigations done if required. Please do not worry. Hope I have answered your query. Let me know if I can assist you further.
