ABSTRACT

Nemaline myopathy is a congenital neuromuscular disorder characterized by nemaline bodies in the muscle fiber. Patients with nemaline myopathy frequently experience respiratory muscle weakness, but it is rare that adult patients are diagnosed with the initial symptoms of respiratory failure. The patient was a 38-year-old woman with severe scoliosis. She developed CO2 narcosis and needed artificial respiration. Initially, she was believed to suffer from the acute progression of chronic respiratory failure as a result of severe scoliosis. However, a high-arched palate was noticed, and a congenital disorder was suspected. A muscle biopsy was performed, which resulted in a diagnosis of nemaline myopathy. Patients with nemaline myopathy frequently experience complications of scoliosis. On the other hand, because respiratory failure can progress in patients with nemaline myopathy, we often overlook the presence of this disease. The performance of a thorough physical examination to make an accurate and timely diagnosis of congenital muscle disorders is therefore important.
