The crazy-paving pattern in exogenous lipoid pneumonia: CT-pathologic correlation

AJR Am J Roentgenol. 1998 Feb;170(2):315-7. doi: 10.2214/ajr.170.2.9456935.


Objective: The purpose of our study was to show a distinctive appearance of exogenous lipoid pneumonia on thin-section CT that has not, to our knowledge, been previously documented.

Conclusion: On thin-section CT, exogenous lipoid pneumonia is revealed as patchy well-defined areas of ground-glass attenuation with superimposed septal thickening (crazy-paving pattern). Exogenous lipoid pneumonia should be included in the differential diagnosis when thin-section CT reveals a crazy-paving pattern.
