Recurrent orbital myositis as an extra-intestinal manifestation of Crohn's disease.

Extra-intestinal manifestations (EIM) of Crohn's disease (CD) affect up to 35% of patients and the presence of one EIM appears to be a predisposing factor for others.1 Orbital myositis (OM) is a subgroup of idiopathic orbital inflammatory syndrome involving one or more extra-ocular muscles and is described as a very rare EIM of CD.2 We present the case of a 55-year-old woman, with Crohn's colitis since 1995, stricturing behavior, with type 2 arthropathy. She underwent a sigmoidectomy in 2004 for a 7-cm stenosis (histology of the surgical piece compatible with Crohn's stenosis). She was treated with sulfasalazine and had no history of steroid therapy or other immunosuppressant therapy. Recurrent joint symptoms were difficult to control.
