ABSTRACT
Objective To analyze the CT imaging features of pulmonary sclerosing haemangioma(PSH),so as to improve the level of the diagnosis of this disease.Methods Retrospectively analyzed the Multi-slice spiral computed tomography(MSCT) imaging data of 13 cases of PSH with who confirmed by surgical pathology,all cases were performed CT with non-enhanced scaning and enhanced.Results 13 patients' average age was 42 years old,including 10 female,accounted for 76.92％ (10/13).All the nodules or masses of the 13 cases were single,long diameter was 0.6-5.0cm,all tumors presented as round or oval shaped,clear boundary.1 case with calcifications in 13 cases,2 cases with air meniscus sign,and 2 cases with halo sign around.Contrast-enhanced:10 cases were enhanced homogeneously,3 cases were enhanced heterogeneously and with vessel marginating sign,1 case of lymph node was enlargement in mediastinal.Conclusion PSH mainly more shows at middle-aged women,it has relative characteristic of CT imaging within non-enhanced scaning and enhanced.Therefore,a comprehensive analysis of these CT features can help to improve the accuracy of diagnosis.
ABSTRACT
Objective To explore the CT imaging features of solid pseudo- papillary tumor of pancreas (SPTP) and the diagnostic value of dual-enhanced scanning in SPTP. Methods CT imaging data of 38 cases with SPTP confirmed by surgical pathology were retrospectively analyzed, among whom there were 20 cases who had underwent dual-phases enhanced scanning and 18 cases who had underwent three-phases enhanced, the CT imaging features of the tumors,enhancement degree and the enhancement peak phase of tumors′solid composition were observed. Results All the tumors were single.Tumor located in the head of pancreas in 14 cases, in the neck in 4 cases,in the body in 8 cases, in the tail in 7 cases, in the body-tail of border in 4 cases,and 1 case in the head-neck of border.The size of tumors was 2.4+7.8 cm;tumor of 12 cases was solid mainly,of 24 cases was solid and cystic,and of 2 cases was cystic mainly. Enhancement was uneven. The solid composition showed mild-to-moderate reinforcement, and the enhanced peak stage was in portal vein phase or delay phase.Conclusions There are some characteristics in CT imaging findings of SPTP, CT imaging combined with clinical characteristics can make an accurate diagnosis before operation. The diagnosis accuracy of SPTP with MSCT through dual- phases enhancement scaning and the three- phases enhancement shows no difference,and the former scaning technology can reduce the received effective radiation dose of patients and improve the efficiency of examining.It is worth of promoting.
