"Crazy-paving" pattern at thin-section CT of the lungs: radiologic-pathologic overview.

摘要: The "crazy-paving" pattern is a common finding at thin-section computed tomography (CT) of the lungs. It consists scattered or diffuse ground-glass attenuation with superimposed interlobular septal thickening and intralobular lines. This has variety causes, including infectious, neoplastic, idiopathic, inhalational, sanguineous disorders. Specific disorders that can cause crazy-paving include Pneumocystis carinii pneumonia, mucinous bronchioloalveolar carcinoma, pulmonary alveolar proteinosis, sarcoidosis, nonspecific interstitial organizing exogenous lipoid adult respiratory distress syndrome, hemorrhage syndromes. Knowledge many causes this be useful in preventing diagnostic errors. In addition, although are frequently indistinguishable radiologic evaluation, differences location characteristic lungs, as well presence additional findings, patient's history, clinical presentation, often suggesting appropriate diagnosis.
