Invasive pulmonary aspergillosis

Invasive pulmonary aspergillosis is a severe, life-threatening opportunistic fungal infection of the lower respiratory tract caused by the inhalation of airborne spores from *Aspergillus* species, most commonly *Aspergillus fumigatus* It primarily develops in severely immunocompromised individuals—such as patients with prolonged neutropenia, hematologic malignancies, or hematopoietic stem cell and solid organ transplants—as well as critically ill patients with severe viral pneumonia Pathophysiol...

It primarily develops in severely immunocompromised individuals—such as patients with prolonged neutropenia, hematologic malignancies, or hematopoietic stem cell and solid organ transplants—as well as critically ill patients with severe viral pneumonia

Pathophysiologically, the organism invades the bronchial mucosa and surrounding pulmonary parenchyma, exhibiting a characteristic hallmark of angioinvasion that leads to thrombosis, tissue necrosis, pulmonary infarction, and potential hematogenous dissemination Patients typically present with fever, cough, dyspnea, pleuritic chest pain, and hemoptysis, often accompanied by characteristic macronodules with surrounding ground-glass attenuation on chest imaging
