During the COVID-19 pandemic, it has been difficult to distinguish between PAP and post-COVID-19 pulmonary sequelae. Here we present a case of a 44-year-old male patient who experienced exertional dyspnea after recovering from COVID-19. He was initially diagnosed with post-COVID-19 syndrome and treated with systemic corticosteroid without improvement. Chest computed tomography (CT) showed crazy-paving pattern with ground-glass opacities. Fibreoptic bronchoscopy with bronchial lavage fluid (BLF) analysis confirmed the final diagnosis of PAP. The patient underwent left lung lavage in combination with conventional therapy and experienced significant improvement in his respiratory condition and overall health during follow-up. Hence, PAP could occur after a COVID-19 infection. This case highlights the importance of considering PAP as a potential diagnosis in patients with persistent respiratory symptoms after COVID-19. The high suspicion indicators of PAP revealed by chest-CT and BLF may be a key to differentiating PAP from post-COVID-19 pulmonary sequelae.
