Not a Fluke: Pulmonary Manifestations of Parasitic Infection

Area of Science:

• Radiology
• Infectious Diseases
• Tropical Medicine

Background:

• Parasitic infections impact 2 billion people worldwide, predominantly in tropical and subtropical regions.
• Increasing immigration and travel lead to a rise in parasitic infections in developed countries.
• Thoracic manifestations of parasitic infections are common, often presenting with nonspecific or overlapping clinical findings.

Purpose of the Study:

• To categorize thoracic manifestations of parasitic infections.
• To highlight the utility of considering nontraditional parasitic pathologies in differential diagnoses.
• To aid radiologists in timely and accurate diagnosis by recognizing classic imaging patterns.

Main Methods:

• Review of literature on parasitic infections and their thoracic manifestations.
• Categorization of thoracic pathologies into nondestructive and destructive types.
• Inclusion of a third category for rare parasitic thoracic involvement.

Main Results:

• Thoracic parasitic infections present as nondestructive (patchy, migratory opacities) or destructive (cysts, inflammation, osseous destruction) patterns.
• A third category of rare parasitic thoracic pathology expands diagnostic considerations.
• Integrating systemic findings with classic thoracic patterns improves diagnostic accuracy.

Conclusions:

• Understanding diverse thoracic manifestations of parasitic infections is crucial for diagnosis.
• Radiologists should consider parasitic etiologies, including rare presentations, in their differential diagnoses.
• Accurate diagnosis relies on recognizing specific imaging findings and systemic correlations.
