Abstract:
A 68-year-old man who was given a diagnosis of interstitial pneumonia. Chest computerized tomography (CT) revealed subpleural honeycomb formations and traction bronchiectasis. Three months after the diagnosis of interstitial pneumonia, he noticed neurological symptoms, such as facial spasms, dysphagia, muscle rigidity and muscle cramp, and repeatedly received clonazepam. He was diagnosed with stiff-person syndrome on electromyography when he was hospitalized due to aspiration pneumonia. He has needed continuous rehabilitation due to the progression of neurological symptoms despite the partial efficacy of anti-epilepsy agents. We report a case of interstitial pneumonia with stiff-person syndrome.
