Review select fibro-inflammatory diseases presenting as masses that may masquerade as malignancies Discuss recent advances regarding pathogenesis & clinico-pathological findings Describe MDCT/MRI/PET-CT findings & the role of radiologist in diagnosis, management & surveillance  

Introduction Taxonomy: Inflammatory pseudotumors, IgG4 sclerosing disease, auto-immune pancreatitis, sclerosing mesenteritis, retroperitoneal fibrosis and auto-immune prostatitis Recent advances in pathogenesis & molecular biology MDCT, MRI & PET-CT findings Natural history & prognosis Conclusion Select fibro-inflammatory diseases of the abdomen and pelvis present with masses that may be mistaken for more common neoplasms. IgG4 related disease has recently been described & current concepts of autoimmune pancreatitis continue to evolve. Biopsy is definitive; select masses show exquisite response to steroids or immunosuppressive drugs. Imaging findings allow initial detection, treatment follow-up & surveillance.
