Autoimmune prostatitis with autoimmune pancreatitis: A case report and review of literature

Autoimmune pancreatitis is a type of chronic pancreatitis characterized by an inflammatory process with lymphoplasmacytic infiltration associated with fibrosis of the pancreas. Various autoimmune extrapancreatic manifestations are associated with this condition which includes biliary pathologies like sclerosing cholangitis, inflammatory bowel disease, sialadenitis, renal and pulmonary lesions and retroperitoneal fibrosis. Autoimmune prostatitis is rarely associated with autoimmune pancreatitis with only a handful number of cases reported so far. Imaging plays a role in differentiating this entity from prostatic cancer and documenting the response to therapy. Increased uptake within the prostate has been described on FDG-PET imaging in cases of autoimmune pancreatitis. However, ultrasound and MRI findings of this entity have not been reported. Hereby, we report a case of autoimmune prostatitis with autoimmune pancreatitis, present ultrasound findings and review the relevant literature.
