Our aim was to add to the list of pseudodystonia published by Berlot et al. a relatively rare, but possible form, describing fibrodysplasia ossificans progressiva (FOP) as an entity that can mimic dystonia (accompanied with video). We also provide the first report on the botulinum toxin type A (BoNT/A) therapy in FOP. We describe potential mechanisms that can be responsible for the good outcome of BoNT/A therapy observed in our patient.

进展性骨化纤维发育不良作为假性肌张力障碍的一种形式。

我们的目标是添加到 Berlot 等人发布的假性肌张力障碍列表中。一种相对罕见但可能的形式，将进展性纤维发育不良 (FOP) 描述为可以模拟肌张力障碍的实体（伴随视频）。我们还提供了关于 FOP 中 A 型肉毒杆菌毒素 (BoNT/A) 疗法的第一份报告。我们描述了可能导致在我们的患者中观察到的 BoNT/A 治疗的良好结果的潜在机制。
