Summary
Crazy paving on CT scans, initially linked to alveolar proteinosis, can also indicate lung adenocarcinoma. This finding highlights the pattern
Area of Science:
- Radiology
- Pulmonary Medicine
- Oncology
Background:
- The "crazy paving" pattern on computed tomography (CT) involves superimposed ground-glass opacity and linear opacities.
- Historically, this pattern was considered pathognomonic for alveolar proteinosis.
- However, the "crazy paving" appearance is now recognized in various pulmonary disorders.
Purpose of the Study:
- To investigate the association between the "crazy paving" CT pattern and lung adenocarcinoma.
- To illustrate CT findings of lung adenocarcinoma exhibiting both solid and "crazy paving" features.
Main Methods:
- Review of CT images from patients diagnosed with lung adenocarcinoma.
- Analysis of imaging features, specifically the presence of "crazy paving" and solid components.
Main Results:
- Demonstration of CT images of lung adenocarcinoma.
- Observed "crazy paving" pattern in conjunction with solid tumor components in lung adenocarcinoma cases.
Conclusions:
- The "crazy paving" pattern is not exclusive to alveolar proteinosis.
- Lung adenocarcinoma can present with a "crazy paving" appearance, alongside solid nodules.
- Radiologists should consider lung adenocarcinoma in the differential diagnosis of the "crazy paving" pattern.
