Fungal Pneumonia in an Immunocompetent Host: A Case Report

<italic>Aspergillus fumigatus</italic> is an opportunistic fungus, found ubiquitously in the environment. <italic>A. fumigatus</italic> typically infects an immunocompromised host. This case report is about a 55-year-old immunocompetent woman who was initially treated with antibiotics after being diagnosed with a pulmonary infection. However, further investigations revealed fungal pneumonia due to <italic>A. fumigatus</italic>. The patient eventually responded to antifungal treatment, although adverse effects of the antifungals were observed. Despite its rarity, it is important to consider other differential diagnoses, such as fungal pneumonia, if the pneumonia does not respond to medical treatment, as well as the potential adverse effects of antifungals.
