Many Faces of Thoracic Histoplasmosis-Pictorial Essay

Area of Science:

• Pulmonology
• Infectious Diseases
• Radiology

Background:

• Histoplasmosis is a significant fungal infection affecting the lungs.
• Its radiological manifestations are highly variable.
• Differential diagnosis can be challenging due to overlapping appearances with other thoracic diseases.

Purpose of the Study:

• To comprehensively review and illustrate the diverse spectrum of chest imaging findings in histoplasmosis.
• To aid clinicians in recognizing histoplasmosis on radiological studies.
• To highlight the mimicry of histoplasmosis with other pulmonary and thoracic pathologies.

Main Methods:

• Review of radiological literature on histoplasmosis.
• Compilation of characteristic and atypical imaging findings.
• Correlation of imaging findings with clinical presentations.

Main Results:

• Histoplasmosis demonstrates a wide range of appearances on chest imaging, including nodules, masses, consolidation, and interstitial patterns.
• Radiological findings can mimic granulomatous diseases, malignancies, and other infections.
• Specific patterns may suggest disseminated or chronic forms of the disease.

Conclusions:

• Chest imaging plays a crucial role in the diagnosis of histoplasmosis.
• Awareness of the varied radiological manifestations is essential for accurate diagnosis.
• Radiologists and clinicians should consider histoplasmosis in the differential diagnosis of diverse thoracic abnormalities.
