Abstract:
Objective:The purpose of this paper is to illustrate different diseases that cause this crazy-paving pattern and to correlate the thin-section CT findings with the histopathological findings. Methods: A retrospective review of the medical records of our radiological computed tomography database was performed from January 2010 until December 2012,searching for patients reported to have a crazy-paving pattern on a thin-section CT of the chest. In total, 83 patients with a crazy-paving pattern were retained and reviewed. Results:The crazy-paving pattern consists of interlobular septal and intralobular interstitial thickening superimposed on an area of ground-glass attenuation on thin-section CT scans. We identified 83 cases that presented with the crazy-paving pattern, inclould infection(bacterial infection n=6,viral infection n=16,fungal infection n=1,and mixed infection n=12); ARDS n=4; acute pulmonary oedema n=3; interstitial lung disease (UIP, NSIP) n=18; adenocarcinomas n=3; lymphangitis carcinomatosis n=3;lymphoma pulmonary infiltration n=2;radiation pneumonitis n=5;sarcoidosis n=1;alveolar proteinosis n=4;alveolar hemorrhage n=4; lipid pneumonia n=1. Conclusion: The crazy-paving pattern on thin-section CT is a non-specific signs, can be seen in infections, tumor, as well as some cryptogenetic diseases. Nevertheless, familiar with these common diseases, allows us to narrow the differential diagnosis, even prompted the diagnosis of certain diseases in the appropriate clinical setting.
