Reactive Axillary Lymphadenopathy Among Different COVID-19 Vaccines: A Retrospective Study in Breast Sonography.

During the coronavirus disease 2019 (COVID-19) outbreak, reactive lymphadenopathy after vaccination is a major concern in breast sonography, especially for patients with a history of breast cancer. The state-of-the-art literature on clinical and sonographic findings either examines a small volume of cases or limited types of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. This study is aimed at providing vast clinical information to facilitate breast sonographic examination for participants who underwent recent SARS-CoV-2 vaccination.

Unenhanced multidetector computed tomography findings in acute central pulmonary embolism.

Background: Computed tomography pulmonary angiography (CTPA) is the gold standard for the diagnosis of pulmonary embolism (PE). However, contrast is contraindicated in some patients. The purpose of this study was to determine the diagnostic accuracy of unenhanced multidetector CT (MDCT) for diagnosis of central PE using CTPA as the gold standard.

A floating thrombus of the right ventricle in severe massive pulmonary embolism.

Floating right heart thrombus (FRHT) is a severe presentation of thromboembolic disease and usually coexists with massive pulmonary embolism. Patients with FRHT are more hemodynamically compromised and usually have a higher mortality rate than patients without FRHT. An echocardiographic finding of FRHT is important because it identifies as poor prognosis.
