ABSTRACT
Objective To investigate the diagnostic significance of microcalcifications in breast cancer.Methods 120 cases of breast lesions with microcalcifications confirmed by pathology were included in this study,of them,97 cases were breast carcinoma,including infiltrating ductal carcinoma(n=71),invasive lobular carcinoma(n=23),and others 3 cases,23 cases were benign breast diseases.All cases underwent mammography,X-ray features of microcalcification were analysed in comparison with that of pathology.Results (1)The microcalcifications of breast in totally 120 cases could be divided into 3 types according to the density of calcifications,those were high (45/120),middle (34/120) and low (41/120) density.The middle and low dense microcalcifications were more seen in breast cancer(73.19%,71/97),high dense microcalcifications were more seen in benign breast diseases(82.00%,19/23).(2)The malignant calcifications were mostly less than 0.5 mm in diameter.The calcifications appeared as sandy in 68/97,bulky in 18,“Y”,“V”,branch or club in 8 and worm in 3.The benign calcifications were mostly more than 0.5 mm in diameter with regular form and defined margin.(3)Dense or clustered microcalcifications were often seen in breast cancer (82/97),scatter and/or bulky microcalcifications were more seen in benign breast diseases(16/23).Conclusion Microcalcification is important finding in diagnosis of breast cancer,espcially early cancer on macrography,but it should differentiate with benign breast microcalcifications.
ABSTRACT
Objective To explore the appearances of DSA and therapeutic methods of tanscatheter hepatic artery chomoembolization (THACE) of hepatic carcinoma with arteriovenous fistula(avf).Methods The indirect hepatic portal vein angiography (Superior mesenteric artery angiography) and celiac trunk angiography (common hepatic artery) were performed in 673 cases with hepatic carcinoma confirmed by pathology,then hepatic artery infusion-chemotherapy and/or embolizations were done. Results Heptic carcinoma to be accompanied with arteriovenous fistula(AVF) 151 was totally cases(22.4%),including artery-portal vein fistula 127 cases,artery-vein fistula 15 cases, mixed 9 cases.Of them, hepatic artery embolizations in 131 cases with artery-vein fistula(86.6%) were performed once or more times, in 20 cases due to the embolization of artery-vein fistula couldn’t be performed and/or with tumor embolus inside common portal vein while only arterial infusion-chemotherapy were performed.Conclusion DSA is accurate and direct diagnostic method in hepatic carcinoma with artery-vein fistula. Hepatic artery embolization and infusion-chemotherapy is an effective way for the patients with artery-vein fistula.
ABSTRACT
Objective To improve the radiological diagnosis of breast cancer .Methods The authors collected 15 cases of breast carcinoma confirmed by operation and pathology. All these cases were misdiagnosed by mammography.Mammographic manifestations and data of clinic were analyzed retrospectively. Results 4 cases changed like small fibroadenoma, 3 cases showed microcalcification, 3 cases showed localized mammary gland architecture distrotion,2 cases showed multiple small patchy shadows in the hyperplasic mammary gland, 2 case showed small focus of increased density, 1 case no abnormal sign, 4 cases among of them can not be palpated mass .Conclusion The combination between palpation and radiology is valuable for diagnosis of breast carcinoma and decreasing misdiagnosis.
