Abstract:
OBJECTIVETo study high resolution computed tomograghy (HRCT) features and changes of HRCT after whole lung lavage therapy in patients with pulmonary alveolar proteinosis (PAP).
METHODWe retrospectively reviewed the HRCT data of 23 times of lung lavage therapy in 16 PAP patients.
RESULTSHRCT scan showed bilateral clearly-defined patchy areas of ground-glass opacity and interlobular septal thickening, a pattern commonly characterized as "crazy paving". After whole lung lavage therapy, HRCT showed that the diffused ground-glass opacity palliated and the extent of lung opacity shrinked, while the reticular opacity and area of confluence persisted.
CONCLUSIONThe HRCT feature of PAP is relatively characteristic, and may be improved after whole lung lavage therapy.
