Maternal Mortality Due to an Undiagnosed Large Thymoma in Puerperium: A Case Report

 Delayed or avoided medical care due to coronavirus disease 2019 (COVID-19) related concerns may increase morbidity and mortality associated with both acute and chronic health conditions. Thymoma is uncommon in pregnancy, although it could be accompanied with unfavorable outcomes. We report a puerperal woman presented with dyspnea and cardiac arrest with a recent diagnosis of thymoma that led to maternal mortality.

 A 38-year-old woman with occasional dyspnea during pregnancy without medical referral was admitted to the hospital with severe dyspnea and orthopnea three days after cesarean section. Spiral computed tomography (CT) angiography showed a 64 × 84-centimeter mass with soft tissue density in the left perivascular that was originated from the anterior mediastinum; in biopsy, thymoma was suggested. She died shortly after due to severe dyspnea and cardiac arrest.

 Prenatal care during COVID-19 pandemic should not be postponed. Indeed, any symptom similar to the physiologic changes in pregnancy needs to be evaluated for optimal clinical management.
