摘　　要：BACKGROUND Extra-intestinal manifestations in inflammatory bowel diseases(IBD)are frequent and involve virtually all organs.Conversely,the clinical characteristics and course of inflammatory myopathies in IBD remain poorly described and mostly related to orbital myositis.Moreover,alternative therapeutic strategies in non-responder patients to corticosteroid therapy must still be clarified.CASE SUMMARY A 33-year-old woman with a history of unclassified colitis presented with acute bilateral calf pain.On admission,her clinical and biological examinations were non-specific.However,magnetic resonance imaging showed bilateral inflammatory changes in gastrocnemius muscles suggestive of myositis.Muscle biopsy confirmed the diagnosis of myositis and demonstrated an inflammatory infiltrate mainly located in the perimysial compartment including lympho-plasmocytic cells with the formation of several granulomatous structures while the endomysium was relatively spared.The combined clinical,biological and histomyopathological findings were concordant with the diagnosis of‘gastrocnemius myalgia syndrome’(GMS),a rare disorder associated with Crohn’s disease(CD).Ileocolonoscopy confirmed CD diagnosis and systemic corticosteroids(CS)therapy was started,resulting in a rapid clinical improvement.During CS tapering,however,she experienced a relapse of GMS together with a severe active ileocolitis.Infliximab was started and allowed a sustained remission of both conditions at the latest follow-up(20 mo).CONCLUSION The GMS represent a rare CD-associated inflammatory myopathy for which anti-tumour necrosis factor-αtherapy might be considered as an effective therapeutic option.
