"FDG-PET "
"PET scan and PET-CT with 18F-fluorodeoxyglucose (FDG) is a reliable tool for assessing the metabolic activity of the mass: in early inflammatory stages the uptake is avid, in the late fibrotic stage there might be no uptake."
"immunosuppressive drugs such as Azathioprine and Methotrexate have been used effectively as steroid-sparing agents and in patients unresponsive to steroids alone."
"Elevated ESR is seen in 80-90% of patients."
"Cyclophosphamide may be useful in severe cases (if vasculitis is present)"

"Common symptoms include dull, diffuse back/abdominal/flank pain (80%), with other symptoms including fever, weight loss, anorexia, vomiting, malaise, claudication, testicular pain, and/or renal colic."
"isolated periaortitis: non-aneurysmal form of chronic periaortitis; less frequently encountered"
"with CE-CT the periaortic mass usually shows varying degree of enhancement; the degree of enhancement correlates with the activity of the fibrotic process"
"in malignancy the fibrosis has a tendency to be larger and bulkier; the sensitivity and specificity of morphologic features are rather poor"
"in chronic disease, little or no enhancement may be seen"
"steroids are usually effective in chronic periaortitis but their role remains somewhat controversial. There is no accepted standard for dose and duration of steroid treatment"
