Abstract: Diaphragmatic eventration (DE) denotes abnormal elevation of the diaphragm due to paralysis, hypoplasia, or atrophy and is classed as either congenital or acquired. In this report, one case involved a patient with congenital localized DE who developed persistent symptoms such as cough, sputum production, chest tightness, and shortness of breath after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Imaging studies ultimately revealed progression to complete DE. The patient underwent surgical intervention and recovered well postoperatively. The other case involved a patient who developed chest tightness, shortness of breath, cough, and sputum production after infection with Influenza A virus. Chest CT imaging confirmed localized DE. Although antiviral treatment alleviated the symptoms, the diaphragmatic elevation remained. This study demonstrates that both SARS-CoV-2 and influenza virus infections can potentially damage the phrenic nerve, leading to subsequent diaphragmatic dysfunction. Early recognition and intervention can effectively prevent progression of DE and ensure prompt, effective treatment.
