Invasive pulmonary aspergillosis due to Aspergillus fumigatus is an often serious mycosis, usually occurring in severely immunocompromised patients. It is accompanied by a high mortality rate due to its often difficult and late diagnosis. Diagnosis is based on early chest computed tomography and mycological examination of respiratory samples. Both patients had presented with acute respiratory distress, developing in a context of fever and deterioration of the general condition despite the initiation of broad-spectrum empirical treatment. In each of them, a chest CT scan was performed, objectifying atypical cavitary images not suggesting pulmonary aspergillosis. Cytobacteriological examination of sputum and search for Mycobacterium tuberculosis were negative. Serology for aspergillus antigens and a sample of bronchoalveolar lavage fluid for a mycological study were requested. Direct examination of bronchoalveolar lavage fluid was negative, but culture allowed the identification of Aspergillus fumigatus. Galactomannan testing was positive. Given these results, treatment with injectable voriconazole was initiated in our two cases. The evolution was marked by a clinical improvement of one patient and the death of the other patient. Invasive pulmonary aspergillosis is a major concern due to the frequency of its complications. Its diagnosis must be early to ensure adequate management for a better prognosis.
