頭顱下垂綜合症(dropped-head syndrome)是一種病人頭抬不起來的症候群。患者共同症狀包含頸部疼痛、吞嚥困難、無法維持水平視線等。有許多神經肌肉疾病都可能導致這些症狀,使得鑑別診斷額外複雜。本篇文章報告一位多發性肌炎(polymyositis)併進行性頭顱下垂達三個月的病患。最後確診主要是依靠肌電圖檢查及抽血結果。病人在接受類固醇治療後,血中肌肉酵素大幅降低且頭顱下垂的症狀明顯改善。本篇文章也整理了頭顱下垂綜合症常見的病因及其治療。雖然盛行率低,但如果缺乏及早治療,頭顱下垂綜合症可能會造成老年人嚴重殘障。因此,及早發現、診斷並轉介轉科進行治療都是非常重要的。
Dropped-head syndrome is a condition in which patients cannot lift their head. Common symptoms include neck pain, dysphagia, and difficulty in maintaining horizontal gaze. The fact that various neuromuscular diseases may cause the syndrome makes differential diagnosis rather complicated. The article presents a case of polymyositis with a progressive dropped head for three months. The diagnosis was mainly based on an EMG study and laboratory examination. After proper treatment with systemic steroids, the patient's serum muscle enzyme level reduced to nearly the upper standard limit, and her symptoms improved significantly. We also reviewed the etiologies and corresponding treatment of dropped-head syndrome. Despite its low prevalence, dropped-head syndrome may cause severe disability among the elderly if left untreated. Early detection, diagnosis, and specialist referral are therefore of great importance.
