Diaphragm paralysis may be either idiopathic or associated with several medical conditions including viral and bacterial infection. The association of phrenic nerve palsy with viral infections is rare but well-appreciated in several case reports. Neuropathy, both central and peripheral, is a common neurological consequence of COVID-19. Here, we describe a case of diaphragm paralysis in a woman who was admitted to the hospital because of COVID-19 pneumonia. Post-COVID-19 unilateral paralyzed diaphragm was diagnosed with a chest X-ray for her and the disorder was attributed to COVID-19 because no other etiology was found to be associated. So far, phrenic neuropathy and diaphragmatic paralysis in a COVID-19-affected patient have not been reported from Iran.
