Sonographic elastography has been shown to be a useful imaging modality in characterizing breast lesions as benign or malignant. However, in preliminary research, mastitis has given false-positive findings on both strain and shear wave elastography. In this article, we review the findings in mastitis with and without abscess formation on both strain and shear wave elastography. The elastographic findings in all cases were suggestive of a malignancy according to published thresholds. In cases of mastitis with abscess formation, there is a characteristic appearance, with a central very soft area (abscess cavity) and a very stiff outer rim (edema and inflammation). This appearance should raise the suspicion of mastitis with abscess formation, since these findings are rare in breast cancers.

Breast lymphomas only account for approximately 0.15% of malignant breast carcinomas. Half of these are primary lymphomas, and the other half are metastatic to the breast. Ultrasound elastography has been proven to aid in the diagnosis of breast lesions as malignant or benign, with malignancy appearing stiffer compared with normal breast tissue. However, in this study, we review the findings of breast lymphoma on strain and shear wave ultrasonography. Lymphoma appears drastically different on sonoelastography than primary breast cancers, and it could easily be interpreted as benign. Therefore, the unique imaging findings in addition to the patient's clinical history are important in differentiating lymphoma of the breast from other possible diagnoses.

OBJECTIVES: To compare the agreement and interobserver variability of diagnostic handheld ultrasound (US) and a single volume on an automated breast volume scanner (ABVS) and to determine whether there was a significant difference if the ABVS was used by a sonographer or mammographic technologist. METHODS: Ninety patients scheduled for diagnostic US examinations were randomized to either handheld US or the ABVS first. The AVBS was randomized between a sonographer and a mammographic technologist performing the study. The studies were blinded, randomized, and read by 2 radiologists. The lesion with the highest Breast Imaging Reporting and Data System (BI-RADS) score was used in the analysis. Final diagnoses were made by core biopsy or follow-up for 2 years. Lesions included 9 malignant and 81 benign. RESULTS: The 90 patients had a mean age +/- SD of 53.1 +/- 16.3 years. The kappa value for agreement between the ABVS and handheld US was 0.831 (95% confidence interval, 0.744-0.925), whereas the global agreement for a 7-point BI-RADS score was 0.488 (0.372-0.560). The agreement between the ABVS and handheld US was nearly the same when the ABVS was used by a mammographic technologist (kappa = 0.858 [0.723-0.963]) or sonographer (kappa = 0.803 [0.596-1.000]; P = .47). The areas under the receiver operating characteristic curves for characterization by the ABVS were 0.91 (0.84-0.96) for reader 1 and 0.91 (0.83-0.96) for reader 2; those for handheld US were 0.91 (0.84-0.96) for reader 1 and 0.83 (0.74-0.90) for reader 2, with no statistical difference. The agreement based on pathologic images was kappa = 0.831 (0.718-0.944); for handheld US, kappa = 0.795 (0.623-0.967); and for the AVBS, kappa = 0.869 (0.725-1.000). CONCLUSIONS: Performing a single-view diagnostic ABVS examination has good agreement with a handheld diagnostic US workup. There is no difference if the ABVS is used by a sonographer or mammographic technologist.
