Assessment of breast cancer size: sonographic and pathologic correlation.

Purpose: Accurate presurgical assessment of tumor size in breast cancer is important for choosing appropriate treatment. We retrospectively compared presurgical sonographic measurements of tumor size with postsurgical measurements of size and other variables.

Methods: In 174 cases, tumor size was measured by sonography before surgery, and those measurements were compared with values obtained by histopathologic examination of the specimens.

Mediastinal lymphadenopathy in cryptogenic fibrosing alveolitis: the effect of steroid therapy on the prevalence of nodal enlargement.

Purpose: To determine the prevalence of enlarged mediastinal lymph nodes in cryptogenic fibrosing alveolitis (CFA) and to assess whether this frequency was related to steroid administration.

Material And Methods: Retrospective review of chest radiographs and high-resolution computed tomography (CT) of 54 patients with proven cryptogenic fibrosing alveolitis (CFA). Twenty-two of the 54 patients received oral steroids up to 2 months before the time of high-resolution CT examination (group 1); the remaining 32 patients had not taken steroids for at least 6 months before study entry (group 2).

Metastatic breast carcinoma in axillary lymph nodes: in vitro US detection.

Purpose: To establish the ultrasonographic (US) characteristics of benign versus metastatic lymph nodes.

Materials And Methods: One hundred fifty-eight axillary lymph nodes in 40 patients (age range, 31-73 years) surgically treated for breast cancer have been studied in vitro with a 7.5-MHz US probe in a water bath.

Imaging findings of sternal abnormalities.

Radiographic findings in the sternal abnormalities are often nonspecific, showing appearances from a localized benign lesion to an aggressive lesion as seen with infections and malignant neoplasms. A specific diagnosis of sternal abnormalities can be suggested on the basis of CT and MR characteristics. Familiarity with the presentation and variable appearance of sternal abnormalities may aid the radiologist is suggesting a specific diagnosis.
