COVID-19-associated Pulmonary Cryptococcosis: A Rare Case Presentation

Area of Science:

• Infectious Diseases
• Pulmonology
• Mycology

Background:

• Opportunistic infections, including aspergillosis and mucormycosis, have been increasingly reported in COVID-19 patients.
• Cytomegalovirus reactivation is also a concern in individuals with severe coronavirus disease-2019.
• Pulmonary cryptococcosis is a fungal infection that can present with a wide range of symptoms, from asymptomatic colonization to severe respiratory distress.

Observation:

• This report presents the first documented case of pulmonary cryptococcosis in a patient who had recovered from severe COVID-19.
• The patient's clinical presentation, radiographic findings, and serologic tests were inconclusive for diagnosing pulmonary cryptococcosis.
• Distinguishing between fungal colonization and invasive fungal disease in the lungs remains a diagnostic challenge.

Findings:

• The case highlights a potential association between severe COVID-19 and the development of pulmonary cryptococcosis.
• The authors propose the term COVID-19-associated pulmonary cryptococcosis (CAPC) to describe this emerging clinical entity.
• Further case reports are needed to establish the prevalence and characteristics of CAPC.

Implications:

• Increased awareness and reporting of such cases are essential for understanding the link between COVID-19 and pulmonary cryptococcosis.
• Diagnostic challenges underscore the need for improved methods to differentiate fungal colonization from invasive disease in post-COVID-19 patients.
• Recognition of CAPC may lead to earlier diagnosis and more effective treatment strategies for this rare but serious complication.
