Abstract:
Pleural aspergillosis is a rare form of invasive bronchopulmonary aspergillosis that is most often seen in immunocompromised hosts. It appears because of the coagulative necrosis of lung tissue induced by the Aspergillus species, which promotes the formation of a fungal pleural effusion. We present the case of a 51-year-old liver transplant patient on chronic immunosuppression therapy who presented with respiratory failure and was found to have a large left-sided pleural effusion from invasive aspergillosis. After thoracentesis, he started antifungal therapy with isavuconazole. This newer, second-generation broad-spectrum triazole is non-inferior to voriconazole but with less hepatotoxicity and was noted to have an improvement in his symptoms. In the differential diagnosis of pulmonary effusions in immunocompromised patients, it is crucial to consider invasive aspergillosis, as demonstrated by our case. This case study highlights the importance of quick diagnosis and treatment to enhance outcomes in this vulnerable population.
Insights
Pleural aspergillosis, a rare fungal infection, can cause respiratory failure in immunocompromised patients. Early diagnosis and treatment with antifungals like isavuconazole are crucial for better outcomes.
Area of Science:
- Medical Mycology
- Infectious Diseases
Background:
- Pleural aspergillosis is a rare invasive bronchopulmonary aspergillosis complication.
- It typically affects immunocompromised individuals, stemming from Aspergillus-induced lung necrosis and subsequent fungal pleural effusion.
Observation:
- A 51-year-old liver transplant recipient on immunosuppressants developed respiratory failure.
- Imaging revealed a large left-sided pleural effusion attributed to invasive aspergillosis.
Findings:
- The patient underwent thoracentesis and initiated antifungal therapy with isavuconazole.
- Isavuconazole, a second-generation triazole, demonstrated efficacy with reduced hepatotoxicity compared to voriconazole, leading to symptom improvement.
Implications:
- Invasive aspergillosis must be considered in the differential diagnosis of pulmonary effusions in immunocompromised patients.
- Prompt diagnosis and treatment are vital for improving outcomes in this high-risk population.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
