Abstract

Purpose : To report the crazy—paving pattern on High Resolution Computed Tomography (HRCT) chest found in our institute which were caused by various processes other than pulmonary alveolar proteinosis (PAP)

Materials and Methods : From June 1998 to August 1999, 4 patients (3 male and 1 female, mean age 38.5 years, range 23-52 years) with crazy-paving pattern on HRCT chest were diagnosed by 2 radiologists. Retrospective review of the imagings was performed with clinical and pathologic correlation.

Results : The crazy-paving pattern in our institute was caused by various processes, including 1 bronchioloalveolar carcinoma, I lipoid pneumonia, | PAP and 1 pulmonary hemorrhage.

Conclusion : From our findings, we can conclude that the crazy-paving pattern is only a nonspecific sign on HRCT chest, resulted from multiple causes. Clinical and pathologic correlation are necessary for differential diagnosis.
