Abstract:
Objective To improve the diagnostic accuracy of pulmonary mucormycosis(PM) by investigating imaging appearances of PM,including CT and PET-CT.Methods A retrospective analysis of unenhanced MSCT(n=14),dynamic enhanced MSCT(n=10) and 18F-FDG PET-CT(n=3) examinations was conducted in 14 patients with surgically and pathologically proven PM.Results CT findings:13 patients had multiple patchy consolidation.Nine had thick-walled cavitiess(n=26) and 4 had pulmonary embolism,1 had solitary irregular masses,3 had adjacent bronchus invasion,4 had pleural effusion,14 had no mediastinal adenopathy.All the patients after renal transplantation had varied ground-glass opacifications and interlobular septal thickenings.The solid portion of lesions had strong enhancement with CT attenduation of (25±8) HU.PET-CT findings:3 cases were found with homogeneously or inhomogeneously increased 18F-FDG uptake(SUVmax 6.2,4.6,3.6).Conclusions PM presents with widespread but lacked specific imaging features.A suggestive diagnosis could be made in some patients with imaging appearances of multiple thick-walled cavities,rapid changes,and complicated with pulmonary embolism or invaded bronchus and sleevelet sign.
