Contrast-enhanced Mammography Artifacts and Pitfalls: Tips and Tricks to Avoid Misinterpretation.

Contrast-enhanced mammography (CEM) involves addition of intravenous iodinated contrast material at digital mammography, thus increasing the ability to detect breast cancer owing to tumor contrast enhancement. After image acquisition, interpretation includes careful assessment of the technique, artifacts, and pitfalls and reporting with a standard lexicon category and appropriate follow-up recommendations. Artifacts and pitfalls that may cause image misinterpretation should be detected and distinguished from pathologic conditions.

Systemic thrombosis in a large cohort of COVID-19 patients despite thromboprophylaxis: A retrospective study.

Background: Incidence of thrombotic events associated to Coronavirus disease-2019 (COVID-19) is difficult to assess and reported rates differ significantly. Optimal thromboprophylaxis is unclear.

Objectives: We aimed to analyze the characteristics of patients with a confirmed thrombotic complication including inflammatory and hemostatic parameters, compare patients affected by arterial vs venous events and examine differences between survivors and non-survivors.

Papillary endothelial hyperplasia (Masson's tumor) developed in the capsule of the implant in a breast cancer patient treated with mastectomy and radiation therapy.

Papillary endothelial hyperplasia (PEH) is an uncommon benign vascular proliferation appearing in soft tissues in different body areas including the breast, which may be related to radiation therapy. A 48-year-old woman previously treated for breast cancer with mastectomy followed by radiation therapy and reconstruction with an implant presented with a newly developing mass in the implant capsule. Pathological diagnosis was PEH.

US of the eye made easy: a comprehensive how-to review with ophthalmoscopic correlation.

When performed by a trained examiner, ultrasonography (US) of the eye is a useful tool in diagnosing conditions of the ocular globe, especially when combined with ophthalmoscopy. Pathologic conditions of the ocular globe include several usual and unusual entities, most of which may be properly identified at US. For instance, the ocular globe may have an abnormal size or unusual morphologic characteristics.

Sonographic and computed tomographic demonstration of hydatid cysts communicating with the biliary tree.

Hepatic hydatid disease is usually silent and discovered incidentally. Rupture of a hydatid cyst into the biliary tree is a serious complication and produces a clinical picture of biliary obstruction. We present the cases of 2 patients who had only nonspecific symptoms and laboratory test results indicative of biliary tract obstruction.
