Abstract:
Objective To evaluate characteristics of CT and 18F-FDG PET/CT in pulmonary sclerosing hemangioma (PSH).Methods A retrospective study involving 12 patients (2 males,10 females;24-80 years old) confirmed as PSH by pathology from May 2012 to July 2014 was investigated.All patients underwent chest CT scan,including enhanced CT;and 5 cases underwent whole-body 18F-FDG PET/CT.All imaging data were collected and analyzed to find out a more effective diagnostic method.Results In 12 PSH patients,9 had single lesion,of which 4 involved left lung and 5 right lung.The rest 3 patients including 1 with two nodules located in the right lower lobe,and 2 with multiple nodules scattered in several lobes.Plain CT showed all lesions had uniformly isodensity,4 with calcification,3 with air meniscus sign.Contrast-enhanced CT examinations showed that the majority lesions were prominent enhancement and few moderate enhancement,all lesions showed vessel marginating sign and 6 with cystic and necrosis area.18F-FDG PET/CT examinations showed that the lesions displayed patchy pattern of mild to moderate uptake with SUVmax 2.2--4.0.Conclusions The characteristic CT features of PSH,especially the contrast-enhanced CT imaging,are important for diagnosis.18F-FDG PET/CT findings are extremely helpful in differentiating PSH from malignant lesions.
