Rare case of sclerosing mesenteritis and low grade follicular lymphoma.

An unusual case of long standing sclerosing mesenteritis; initially presented with recurrent abdominal pain and a mesenteric mass with surrounding fat oedema and stranding with a pseudocapsule and fat ring sign were clearly visualised on the initial computed tomography scan. Laparotomy showed diffuse thickening at the root of the mesentery and histology from this specimen revealed fat necrosis and reactive lymphoid tissue consistent with sclerosing mesenteritis. Initial treatment with steroids and tamoxifen relieved the symptoms and the mass. He was maintained on tamoxifen. Three years later he developed a recurrence of his symptoms and abdominal mass that responded to a course of steroids. Two years following this, he developed a follicular Hodgkin's lymphoma.
