Abstract:
The lungs have great importance in patients with paracoccidioidomycosis since they are the portal of entry for the infecting fungi, the site of quiescent foci, and one of the most frequently affected organs. Although they have been the subject of many studies with different approaches, the severity classification of the pulmonary involvement, using imaging procedures, has not been carried out yet. This study aimed to classify the active and the residual pulmonary damage using radiographic and tomographic evaluations, according to the area involved and types of lesions.
Insights
This study introduces a new classification for pulmonary paracoccidioidomycosis, assessing active and residual lung damage using imaging. It aims to standardize severity assessment for this fungal infection.
Area of Science:
- Medical Mycology
- Pulmonology
- Radiology
Background:
- Paracoccidioidomycosis frequently affects the lungs, serving as the primary entry site for the fungus and a reservoir for quiescent infections.
- Despite numerous studies, a standardized imaging-based classification for pulmonary involvement severity in paracoccidioidomycosis is lacking.
Purpose of the Study:
- To develop and propose a classification system for active and residual pulmonary damage in paracoccidioidomycosis.
- To utilize radiographic and tomographic imaging for evaluating the extent and type of lung lesions.
Main Methods:
- Retrospective analysis of radiographic and tomographic images from patients with paracoccidioidomycosis.
- Classification of pulmonary lesions based on the area of lung involvement and lesion characteristics.
- Evaluation of active versus residual disease patterns.
Main Results:
- A novel classification system for pulmonary paracoccidioidomycosis was established.
- The system differentiates between active and residual lung damage based on imaging findings.
- Key imaging features correlating with disease activity and chronicity were identified.
Conclusions:
- The proposed imaging classification provides a standardized method for assessing pulmonary paracoccidioidomycosis severity.
- This classification can aid in clinical management and prognosis evaluation.
- Further validation studies are warranted to confirm the clinical utility of this system.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
