Introduction and importance Several complications after corona viral infection-19 (COVID-19) have been reported. The study aims is to present a case with post-covid-19 pulmonary fungal infection with antifungal resistance characteristics. Case presentation A 50-year-old male presented with hemoptysis, dyspnea, cough, fever, and rigor for 4-month duration. Three weeks before this complaint, he had cured of COVID-19. Investigations showed multiple ill-defined cavitary lesions involving the left upper lobe. The patient underwent a left upper lobectomy. The post-operative period was uneventful. Clinical discussion All studies of COVID-19 fungal infections reported occurrence during the COVID-19 infection, mostly 14 days after the appearance of COVID-19 symptoms. The case in the current study was a 50-year-old patient, who was previously diagnosed with COVID-19 for a period of 4 months. After a few days from his recovery, the patient developed dyspnea, cough, fever, and rigor again. Conclusion Pulmonary aspergillosis is a serious complication of COVID-19 patients that may not respond well to medical therapy. Pulmonary resection is the last and effective strategy to control the disease.
