Local Tumor Staging of Breast Cancer: Digital Mammography versus Digital Mammography Plus Tomosynthesis.

Background Combined digital mammography (DM) and digital breast tomosynthesis (DBT) (hereafter, DM plus DBT) has increased cancer detection rates when compared with those achieved with DM-only screening. However, there is limited literature on DBT as an adjunct to mammography in the staging of known breast cancers. Purpose To compare the diagnostic accuracy of DM alone with that of DM plus DBT in the identification of additional ipsilateral and contralateral lesions in women with newly diagnosed breast cancer.

Underestimation Rate at MR Imaging-guided Vacuum-assisted Breast Biopsy: A Multi-Institutional Retrospective Study of 1509 Breast Biopsies.

Purpose To assess the rate of underestimation of atypical ductal hyperplasia (ADH) and ductal carcinoma in situ (DCIS) at magnetic resonance (MR) imaging-guided vacuum-assisted breast biopsy and to explore the imaging, demographic, and histologic characteristics associated with lesion upgrade after surgery. Materials and Methods This retrospective study had institutional review board approval, and the need to obtain informed patient consent was waived. A total of 1509 MR imaging-guided vacuum-assisted biopsy procedures were performed in nine centers.

[Breast surgeon role in the management of high-risk breast lesions].

Diagnostics of high-risk breast lesions have increased these last years with the augmentation of breast percutaneous biopsies. They are lesions that confer an enlarged risk of breast cancer, either because of an increased probability of finding cancer after open surgery, a possible evolution toward in situ or invasive cancer, or because of an increased probability of developing breast cancer over the long term. Much progress has been made these last years in their histological diagnostic, classification and pathogenesis.

[Anticoagulant therapy complicated by ureteric haematoma: A case report].

Bleeding of the ureteral wall during an anticoagulant treatment is a rare complication. We report the case of a 57-year-old white woman presented with macroscopic haematuria and lumbar pain with an overdose of anticoagulant treatment. Computed tomographic scan revealed the bleeding of the ureteral wall.

Value of computed tomography in the diagnosis of the cause of nontraumatic gastrointestinal tract perforation.

Objective: To identify computed tomographic features with a high predictive value to differentiate gastroduodenal ulcer perforations from other causes of perforations in patients with a non-traumatic-free pneumoperitoneum.

Materials And Methods: Computed tomographic scans of 81 patients with a non-traumatic-free pneumoperitoneum were reviewed for direct visualization of the perforation site and indirect findings of the perforation, including the presence, amount, and localization of air and ascites in the peritoneal cavity, mural thickness of the gastrointestinal tract, perigastrointestinal fat stranding, intestinal ischemia, fecal peritonitis, abscess, and portomesenteric venous gas.

Results: The perforation site was directly visualized in 16 (41%) of 39 patients with gastroduodenal ulcer perforation and in 5 (12%) of 42 patients with other causes of perforation.
