    Abstract:
    Objective To investigate the X-ray diagnostic significance of calcification of the breast tumor without mass.Methods Mammograms of 90 cases of breast tumor without mass confirmed pathologically were retrospectively analyzed.There were 55 cases confirmed benign breast tumor,and the rest cases were breast cancer.The shape,distribution,total number,location of calcifications in the breast,and asymmetric dense of the breast were recorded and watched.Results ①The X-ray findings of calcification in benign breast tumors always presented as coarse granular(31),scattered shape(35) with small number,less with the asymmetric dense of the breast(7),and the change of side with axillary lymph node(2).②Meanwhile,fine sand-like(32),showing the cluster-like distribution(24) with larger number,with the asymmetric dense of the breast(24) and the change of side with axillary lymph node(10).Both of the differences of the calcifications(the shape,the distribution,and the total number) were statistically significant(P0.05).Conclusions The calcifications of benign and malignant breast tumors have their unique X-ray characteristics.And there is a great value in differentiating early benign and malignant breast tumor.

    The purpose of this series was to review the spectrum of sonographic and mammographic features of granular cell tumors (GCTs) of the breast and to compare their frequency relative to breast carcinoma.Ten cases of a breast GCT diagnosed during the last 13 years were analyzed for the imaging characteristics and clinical features. Sonographic images were reviewed for location, size, echogenicity, margins, height-width ratio, and sound transmission. Mammograms were reviewed for tumor size, location, margin characteristics, spiculations, and calcifications. The frequency of GCTs was compared with that of breast carcinoma during the same study period.Of 10 GCT cases, 9 tumors occurred in female patients, and 1 occurred in a male patient. The mean patient age was 51.8 years, and the mean lesion size was 1.57 cm. All 7 tumors visualized on sonography were hypoechoic masses. Posterior enhancement was noted in 3 of 7 cases, and posterior shadowing was noted in 2 of 7 cases. Two of 7 did not show any posterior enhancement or shadowing. Two of 7 masses were taller than wide. Of 8 tumors visualized on mammography, 5 were spiculated, and 3 were well circumscribed. Calcifications were not visualized in any tumor. During the same period, 1482 cases of breast carcinoma were diagnosed, making the frequency of GCTs of the breast about 6.7 per thousand breast carcinomas.Granular cell tumors of the breast are rare neoplasms with a relative frequency of 6.7 per thousand breast carcinomas in our series, which was higher than reported in literature. Spiculations are a common imaging feature and mimic carcinoma when present.

    Objective To evaluate the applied value of CT in breast lesions.Methods Imaging data of 120 patients with normal breast were reviewed retrospectively in 4 groups of different age(15~25,26~35,36~50 and 51~80),and imaging data of 49 patients with breast lesions biopsy-proved were also analysed.Of 49 breast masses,31 were malignant tumor,18 were benign lesion.All the patients underwent CT scan with supine position whole thoracic region.Results The CT imaging features of normal breast in different age groups were different.65% of normal people had small sporadic axillary lymph nodes.Breast cancer usually showed hillslike and benign tumor showed round oroval-shap.The signs of spiculated lesion,deformed adipose space and thicken of local skin were statistical difference between benign and malignant lesions(P0.05),but lobulated mass,calcificated mass and retracted nipple were not.The difference of density between lesions and normal breast tissue at plain CT between malignant and benign mass were not statistically significant(P0.05).The metastatic axillary lymph nodes usually showed as the significant enlarged nodes with indefinite margin or multiple small nodes.Conclusion CT scan is valuable in detecting breast disease and differential diagnosis,and also can offer the informations on tumor staging and treatment.

    Objective To explore the relationship between the ultrasonography character of breast tumor and the histopathology diagnosis,so that we can diagnose the breast malignant lesion with the Duplex more exactly.Methods To analyze a total of 46 breast tumor patients' histopathology and the ultrasonography image.Results The feature of breast benign tumors includes the distinct boundary,the regular shape,the uniform echo pattern,the vascularity adjacent to lesion and no microcalcifications in mass.On the other hand,the malignant lesion has the opposite feature.Conclusion The feature of breast tumors,such as the lesion boundary,the shape,the echo pattern,the microcalcifications in mass and the vascularity,is very important to differentiate benign from malignant breast lesions.

    Purpose : To analyze the radiologic findings of metastatic tumors of the breast. Materials and Methods : We retrospectively analyzed the findings of mammography (n=12), ultrasonography (n=9) and CT (n=4) of 13 patients with metastatic tumors of the breast. Methods for confirmation were biopsy (n=8) and clinical follow-up (n=5). The patient ’s ages ranged from 24 to 63 (mean 43) years. Results : Primary malignancies were contralateral breast cancer (n=3), non-Hodgkin ’s lymphoma (n=3), stomach cancer (n=2), uterine cervix cancer (n=1), laryngeal cancer (n=1), esophageal melanoma (n=1), ma-lignant thymoma (n=1), and lung cancer (n=1). Patterns of metastasis from contralateral breast cancer and the stomach cancer were diffuse and infiltrative, while metastasis from other cancers was of the focal mass-forming type. The radiologic findings of metastasis from contralateral breast cancer (n=3) were diffuse skin thickening and increased density or echogenicity in the medial aspect of the breast, while in cases involving metastasis from stomach cancer (n=2) radiographs revealed extensive skin thickening, increased density or echogenicity, lymphedema and ipsilateral lymphadenopathy in the left breast. In cases of metastatic tumors to the breast in which focal masses were seen on mammography (n=7), marginal spiculation or microcalcification of the tumors was not present. In six such cases, ultrasonography revealed well-defined margin, posterior acoustic shadowing or an irregular thick echogenic boundary was not seen. In two patients who underwent CT scanning, well-defined masses with moderate contrast enhancement were present. Conclusion : Radiographs of metastatic tumors to the breast from contralateral breast cancer and stomach cancer showed diffuse infiltration. The metastatic tumors with focal masses showed oval to round, smooth-marginated, well-defined masses without spiculation or microcalcification on mammography, and a well-defined mass without posterior acoustic shadowing or irregular thick echogenic boundary on ultrasonography.

    Objective To assess the ultrasonographic characteristics of the benign and malignant calcification in breasts, in order to differentiaiate the benign and malignant breast tumors. Methods Breast calcifications in 64 patients were retrospectively reviewed and compared with pathology as well as mammography. The ultrasonographic characteristics of the breast benign and malignant calcifications were analyzed for improving the differential diagnosis. Results All of the 64 patients had pathologic results. There were 30 cases with benign calcification and 34 with malignant calcification. The characteristics of malignant calcification revealed nodules, with microcalcification appearing multiple punctuation, cluster without acoustic shadowing and absence of color Doppler twinkling artifact. The benigh calcification revealed small amount of coarse, aniso-shape, plague-like or ball like nodular or non-nodular focuses with back shadowing and color Doppler twinkling artifact. The detection rate of the micro calcification between the benign and malignant tumors was significantly different (P0.05). The constituent ratio of micro calcification, coarse calcification and plaque calcification have extremely significant difference between the benign and malignant tumors (P0.01). The sensibility、specificity and accuracy of the ultrasound in diagnosing breast cancer were 94.1%, 93.3%and 93.8% respectively, indicating no significant difference between the ultrasound and the mammography. Conclusions Ultrasound and the mammography are all the important modelities for the diagnosis of breast calcification. The ultrasonographic characteristics of the benign and malignant calcification may conduce the differential diagnosis of breast tumors.

    In this article, X ray plain films with 111 cases calcification of breast were analyzed conjioning with clinical characteristics and pathologic data, and it was found that the features of calcification were contribute to differention of the benign or the malignant. Of the 111 cases, 78 cases were showed benign lesions, and 33 cases malignant lesions. It was concluded that calcification was not the sepecific sign for the carcinoma of breast, which also was seen in benign lesions of breast. If mutiforms and irregular calcifications were appeared in cluster of particle calcification, malignant diagnosis would be predicted.
