We analyzed the mammographic (n=21) findings (location, margin, shape, cluster microcalcifications, size, multiplicity) and ultrasonographic (n=12) findings (shape, border, internal echo, boundary echo, posterior echo, lateral echo, width/depth ratio) to evaluate specific radiologic findings of histopathologically proved uncommon breast cancer. The mammographic findings (n=21) are as follow; 1) single; 16, multiple; 5 2) margin (smooth; 13, irregular; 4, spiculated; 4) 3) shape (round and ovoid; 9, lobulated; 8, irregular; 4) 4) cluster microcalcifications (abscent; 20, present; 1) 5) size (1-3cm; 18, 3-5cm; 2, 5cm> ; 1) 6) location (UOQ; 13, UIQ; 4, LIQ; 3, LOQ; 1). The ultrasonographic findings (n=12) are as follow; 1) shape (round to oval; 5, lobulated; 5, irregular; 2) 2) border (smooth even; 9, rough uneven; 3) 3) internal echo (fine homogeneous; 5, coarse heterogeneous; 7) 4) boundary echo (regular fine; 4, irregular thick; 8) 5) posterior echo (enhanced; 11, no change; 1) 6) lateral echo (marked; 7, nonexistent; 5) 7) width/depth ratio (1.5> 1, 1.0-1.5; 7, 1.0< ; 4). Uncommon breast cancer show benign nature on mammogram, but malignant nature on ultrasonogram (especially boundary echo, internal echo, width/depth ratio)

We encountered a patient with a breast mass which had metastasized from gastric carcinoma representing as aninflammatory carcinoma on ultrasonography. We described the radiologic and clinical features, and review theliterature. The patient had advanced gastric carcinoma and breast ultrasonography demonstrated the presence ofvery ill-defined, infiltrating, and mixed echoic lesions indistinguishable from findings of primary inflammatorybreast carcinoma. Metastatic gastric adenocarcinoma was confirmed pathologically.

PURPOSE: To compare 3D ultrasound (3D-US) with 2D ultrasound (2D-US) in terms of their usefulness and limitations in the diagnosis of breast masses. MATERIALS AND METHODS: We obtained 2D and 3D US images of 37 breast lesions present in 20 cases of fibroadenoma, nine of cancer, and eight of fibrocystic disease proven in a total of 26 cases [fibroadenoma (n=13), breast cancer (n=9), fibrocystic disease (n=4)] by histologic examination, and by clinical evaluation and clinical evaluation with sonographic imaging in eleven. When comparing 3D and 2D-US images we had no prior information regarding detection rate according to the size of lesions, whether or not internal and boundary echo patterns could be interpreted, accurate differentiation between tumorous and non-tumorous lesions, or the accuracy with which benign and malignant tumors could be differentiated. RESULTS: For lesions of 1 cm or less in diameter the detection rate of 3D-US was lower than that of 2D-US, but for lesions over 1 cm there was no difference between the two modalities. In fibroadenoma and breast cancer, 3D-US was more useful than 2D-US for the evaluation of both internal and boundary echo, but with fibrocystic disease and in the diagnosis of tumor/non-tumor, there was no significant difference. In breast cancer, however, 3D-US more accurately determined malignancy, and in fibroadenoma, because of the pseudospicule revealed by 3D-US, this modality was less exact in determining benignancy. CONCLUSION: In the evaluation of internal and boundary echo in breast mass diagnosis, 3D-US was more useful than its 2D counterpart. For lesions of 1 cm or less in diameter, however, the detection rate of 3D-US was low, and since in some benign cases a pseudospicule was apparent, the possibiliy of confusion with malignancy arose. For these reasons, the usefulness of 3D-US was limited.

One hundred and fifty two patients presenting with palpable primary breast cancer were studied to evaluate accuracy of clinical assessment, mammography, and ultrasonography in measuring tumor size. The clinical, mammographic, and ultasonographic diameter of tumor size was compared to histological diameters. The histological diameter of tumors was 27.9+/-12.7mm. The average diameter of tumor on clinical assessment was 33.8+/-13.1mm and its correlation coefficient to the histological size was 0.73. The average size on the mammography was 21.4+/-9.0m and its correlation coefficient to the histological size is 0.71. The tumor size on the ultrasonography in 22 patients was is 22.3+/-10.4mm. The sonographic measurement dimonstrated the highest correlation coefficient (0.83). The clinical assessment overstimated the tumor size, but the mammogaphic and sonographic measurement understimated it compared with histological size. The combined measurement with clinical and ultrasonography could be useful method to estimate tumor size preoperatively. And when it is combined with clinical assessment, it is the most reliable and accurate technique.

Irregular hypoechoic masses in the breast do not always indicate malignancies. Many benign breast diseases present with irregular hypoechoic masses that can mimic carcinoma on ultrasonography. Some of these diseases such as inflammation and trauma-related breast lesions could be suspected from a patient's symptoms and personal history. Careful ultrasonographic examination and biopsy could help to differentiate these from malignancies.

OBJECTICE: To compare the use of conventional, real-time compound, and pulse-inversion harmonic imaging in the evaluation of breast nodules. MATERIALS AND METHODS: Fifty-two breast nodules were included in this study, conducted between May and December 2000, in which conventional, real-time compound, and pulse-inversion harmonic images were obtained in the same plane. Three radiologists, each blinded to the interpretations of the other two, evaluated the findings, characterizing the lesions and ranking the three techniques from grade 1, the worst, to grade 3, the best. Lesion conspicuity was assessed, and lesions were also characterized in terms of their margin, clarity of internal echotexture, and clarity of posterior echo pattern. The three techniques were compared using Friedman's test, and interobserver agreement in image interpretation was assessed by means of the intraclass correlation coefficient. RESULTS: With regard to lesion conspicuity, margin, and internal echotexture of the nodules, real-time compound imaging was the best technique (p < 0.05); in terms of posterior echo pattern, the best was pulse-inversion harmonic imaging (p < 0.05). Real-time compound and pulse inversion harmonic imaging were better than conventional sonography in all evaluative aspects. Interobserver agreement was greater than moderate. CONCLUSION: Real-time compound and pulse-inversion harmonic imaging procedures are superior to conventional sonography in terms of both lesion conspicuity and the further characterization of breast nodules. Real-time compound imaging is the best technique for evaluation of the margin and internal echotexture of nodules, while pulse-inversion harmonic imaging is very effective for the evaluation of the posterior echo patterns.

Breast ultrasound and mammography are established procedures for the diagnosis of breast masses while new technology is opening the door for early cancer diagnosis. The limitation of ultrasound and mammography is that they are only based on physical properties. Recently, using a color doppler system, detection of color flow signal and a resistance index that depend on the blood flow and the blood velocity was applied for diagnosis of breast malignancy. Sixty-five patients admitted for breast surgery were studied. The final diagnosis was made by pathology for thirty malignancies and thirty-five benign lesions. The color doppler measurements on the breast lesions were made preoperatively. The following parameter were assessed :flow velocity, color signal grade and resistance index. The results are as follows: 1) Color signals were detected in twenty-four of the thirty malignancies and in seven of thirty-five benign lesions. 2) Malignant lesions showed a significantly higher maximum velocity (mean=12.52 cm/sec vs 6.34 cm/sec). 3) The resistance index values in the malignancies was higher compared to that in the benign lesions (P < 0.01), a cutoff point 0.6 was used. 4) The color signal grade was grade 0 and I in thirty-four cases of the benign breast lesions (97%) and grade II and III in fifteen of the malignant breast lesions (50%). 5) In breast cancer, the color signal was detected more often in large masses above 2 cm is size,but the result was not statistically significant (P > 0.05). Color doppler flow examination is a useful method for evaluation of benign and malignant breast lesions.
