Boeck sarcoidosis of the breast: mammographic, ultrasound, and MR findings.

The rare case of sarcoidosis of the breast is presented. The mammographic, ultrasound, and MR appearances are described.

[Can the high-resolution 13-MHz ultrasonography facilitate the preoperative localization and marking of microcalcification clusters?]. / Kann die hochauflösende 13-MHz-Sonographie die präoperative Lokalisation und Markierung von Mikroverkalkungsgruppen erleichtern?

PURPOSE: The value of 13 MHz ultrasound regarding the preoperative localisation in combination with mammography were investigated into. MATERIAL AND METHOD: Out of 112 mammaographically detected calcifications, 30 (30 patients) were clusters of microcalcifications. Out of these, 23 were classified as suspicious of malignancy and were preoperatively localised with a 7.5 and 13 MHz probe. Upon marking the skin, a fine needle was inserted, and after due correction blue dye or coal solution was instilled. RESULTS: Following mammographically shown position, 23 clusters of microcalcifications could be localised using the 13 MHz probe. A localisation with the 7.5 MHz probe was impossible in all cases. A single correction of the needle's site was necessary with 35% (8/23) of patients. The maximum distance of the needle's tip in case of misposition measured 11 mm. CONCLUSION: Giving a known mammographic position and a sonographic perceptibility of clusters of microcalcifications in a maximal depth of penetration of 2 cm, 13 MHz high resolution ultrasound examination in combination with mammography prove to be a valuable means in facilitating the preoperative localisation.
