Myositis of pterygoid muscles and superior ophthalmic vein and cavernous sinus thrombosis in active Crohn’s disease undergoing ustekinumab treatment: a case report and literature review

Our report accounts for the second patient described in literature with myositis associated with CD while being treated with UST. The causal factor remains speculative, as both active CD and UST treatment may contribute to this complication. Sharing clinical experiences and reporting possible adverse events to regulatory agencies can enhance our understanding of rare complications and improve patient outcomes by providing therapeutic strategies.
