BACKGROUND: Neuralgic amyotrophy is characterised by ache within the neck or shoulder area, adopted by neuropathy of each motor and sensory nerves of the brachial plexus. The incidence of this situation is estimated at 1/1000 per yr. In a uncommon variant of the syndrome, involvement of each phrenic nerves can happen, resulting in diaphragmatic paralysis and extreme orthopnoea.
CASE DESCRIPTION: A 67-year-old girl was referred to us with acute orthopnoea. Imaging research confirmed bilateral diaphragmatic paralysis, and electromyography (EMG) confirmed neuropathy of each phrenic nerves. The prognosis was bilateral neuralgic amyotrophy. The affected person acquired nocturnal air flow help through nasal excessive circulate oxygen remedy. This symptomatic therapy had a constructive impact.
CONCLUSION: Remoted phrenic nerve neuropathy is a uncommon variant of neuralgic amyotrophy, resulting in orthopnoea. Restoration is gradual and often incomplete. Supportive therapy with non-invasive air flow help is critical to enhance the affected person’s high quality of life.
