Abstract

A 45-year-old man with a raised body mass index presented with an acute history of right lower chest pain and increasing breathlessness. C reactive protein, D dimer and cardiac echocardiography were negative, with mild bibasal atelectasis the only positive reported finding from erect chest X-ray and CT pulmonary angiogram. He was discharged with antibiotics for a chest infection. He remained severely breathless and was referred to the sleep-related breathing disorders clinic. He described shoulder pain, daytime tiredness and sleeping upright due to a ââ'¬Ëœsuffocatingââ'¬â"¢ sensation. The video demonstrates the clinical findings. The CT topogram confirmed bilateral diaphragmatic paralysis. Spirometry demonstrated an 80% reduction in forced vital capacity in the supine position, when compared with erect. Consultation with a neurologist yielded the diagnosis of neuralgic amyotrophy, leading to bilateral diaphragmatic paralysis. The respiratory symptoms have been controlled with night-time non-invasive ventilation, allowing him to sleep supine.
