Invasive pulmonary aspergillosis in a patient with cirrhosis

Area of Science:

• Mycology
• Critical Care Medicine
• Infectious Diseases

Background:

• Aspergillus molds are common environmental fungi capable of causing severe invasive infections.
• Invasive fungal infections, particularly aspergillosis, are frequently underdiagnosed in critically ill patients.
• These infections often lack typical clinical presentations in immunocompromised individuals.

Purpose of the Study:

• To highlight a case of invasive pulmonary aspergillosis in a critically ill patient without classic risk factors.
• To review the diagnostic challenges and management strategies for invasive fungal infections in critically ill populations.
• To emphasize the importance of considering invasive fungal infections in undiagnosed sepsis cases.

Main Methods:

• Case presentation of a 68-year-old female with multiple comorbidities presenting with sepsis-like symptoms.
• Review of diagnostic workup, including imaging and laboratory tests, which were initially non-diagnostic for fungal infection.
• Autopsy confirmation of invasive pulmonary aspergillosis.

Main Results:

• The patient presented with non-specific symptoms and negative routine infectious workup, leading to delayed diagnosis.
• Chest imaging revealed nodular densities and bilateral opacities, suggestive of pneumonia.
• Autopsy confirmed invasive pulmonary aspergillosis, revealing the true cause of the patient's decline.

Conclusions:

• Invasive fungal infections, such as aspergillosis, are often missed in critically ill patients, especially those without typical risk factors.
• High mortality rates associated with invasive fungal infections necessitate increased clinical suspicion and prompt diagnosis.
• Consideration of invasive fungal infections is crucial in the differential diagnosis of critically ill patients with unexplained sepsis or respiratory failure.
