Retroperitoneal Adenopathy

What Is A Retroperitoneal Adenopathy?

Swelling behind the lymph nodes located behind the peritoneum is referred to as retroperitoneal adenopathy. The lining between the pelvic and abdominal cavities is known as the parietal peritoneum. What this tells one is that it is swelling of the lymph nodes around the abdominal area.

Patients with this condition need to have a CT scan so that this can be evaluated. This is the only way to practically and conveniently do this. It is interesting to note that even while patients may have normal sized lymph nodes, they could still have metastases or spreading of the cancer.

This poses a problem, as it cannot therefore be assumed that as there is no adenopathy, that metastases is not present. Patients who have nodal involvement have a very high chance of having some cancerous activity. Adding to this confusion, patients could have hyperplastic lymph nodes and there may be no tumor involvement at all.

CT scanning is however able to detect adenopathy. Furthermore, it is useful in monitoring the results of treatment that has been administered. In the absence of intravenous contrast, it will be very difficult to differentiate between an abdominal aortic aneurysm and large mass of lymphadenopathy of the aorta.

CT scans are also able to display metastatic disease of the abdominal organs as well as the mesenteric regions. Various diseases of the defense system of the body will cause adenopthy to be present. This is where the lymph nodes are swollen.

Therefore, retroperitoneal adenopathy can be as a result of many conditions. It can also be the case that retroperitoneal fibrosis may present with symptoms and this could support the diagnosis. A survey done revealed that out of ten patients there were in fact three different conditions present. Furthermore, it is possible that a CT scan will reveal a mimicking retroperitoneal fibrosis.
