摘　　要：BACKGROUND Diaphragmatic paralysis is typically associated with phrenic nerve injury.Neonatal diaphragmatic paralysis diagnosis is easily missed because its manifestations are variable and usually nonspecific.CASE SUMMARY We report a 39-week-old newborn delivered via vaginal forceps who presented with tachypnea but without showing other birth-trauma-related manifestations.The infant was initially diagnosed with pneumonia.However,the newborn still exhibited tachypnea despite effective antibiotic treatment.Chest radiography revealed right diaphragmatic elevation.M-mode ultrasonography revealed decreased movement of the right diaphragm.The infant was subsequently diagnosed with diaphragmatic paralysis.After 4 weeks,tachypnea improved.Upon re-examination using M-mode ultrasonography,the difference in bilateral diaphragmatic muscle movement was smaller than before.CONCLUSION Appropriate use of M-mode ultrasound to quantify diaphragmatic excursions could facilitate timely diagnosis and provide objective evaluation.
