Summary
Pulmonary alveolar proteinosis (PAP) can present unusually on CT scans. Radiologists should recognize these atypical findings, such as localized or unilateral disease, for accurate diagnosis.
Area of Science:
- Radiology
- Pulmonary Medicine
- Medical Imaging
Background:
- Pulmonary alveolar proteinosis (PAP) is a rare lung disease.
- Characterized by surfactant material accumulation in alveoli.
- Classic CT findings include diffuse ground-glass opacity (GGO) and crazy-paving pattern.
Purpose of the Study:
- To report unusual presentations of Pulmonary alveolar proteinosis (PAP).
- To highlight the importance of recognizing atypical imaging findings.
- To aid radiologists in accurate diagnosis of PAP.
Main Methods:
- Case report of two young male patients with PAP.
- Analysis of computed tomography (CT) imaging findings.
- Documentation of localized and unilateral PAP presentations.
Main Results:
- One patient presented with localized PAP in the left lower lobe.
- The second patient showed unilateral PAP in the right lower lung field.
- Recurrence of unilateral PAP in the same location and pattern was observed.
Conclusions:
- PAP can exhibit atypical imaging findings beyond classic patterns.
- Radiologists must consider localized or unilateral PAP presentations.
- Awareness of these variations improves diagnostic accuracy for PAP.

16
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.

01:14Atypical Pneumonia
73
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease...
