Different imaging presentations of PLCH at clinical onset. Definitive diagnosis obtained by VATS performed within a month of imaging. a A 48-year-old woman, smoker, symptomatic for dry cough and mild fever. A 3-mm collimated CT shows a pattern of early “florid” disease characterised by numerous scattered nodules, of which almost all are cavitated and surrounded by ground glass opacities. A consolidation area also coexists (arrow). b A 46-year-old woman, symptomatic for dry cough and mild fever. HRCT scans show diffuse ill-defined micronodularity, cavitating nodules, cysts and mild interstitial thickening. c A 50-year-old woman, smoker, symptomatic for dry cough. HRCT scans show cystic disease with a few scattered micronodules
