[A case of Churg-Strauss syndrome presenting with lower cranial neuropathy]

We reported a 60 year-old man with Churg-Strauss syndrome (CSS). Three months later, he presented with dysarthria, dysphagia and severe headache. We detected glossopharyngeal and vagal nerve palsy, and made a diagnosis of cranial nerve involvement comorbid with CSS. Intravenous administration of methypredonisolone was effective for alleviating clinical signs and symptoms. Two months later, he complained of headache and facial numbness, but symptoms improved with an escalating dose of prednisolon. As compared to previously reported cases, our case was characteristic because of involvement of lower cranial nerve with CSS, which has been reported previously in only one case.
