Caseous mitral annulus calcification: A forgotten benign condition mimicking cardiac mass, a case report.

Key Clinical Message: Caseous mitral annulus calcification is a rare benign condition that can be misdiagnosed on echocardiography especially when it presents as a mass. This report highlights the contribution of cardiac MRI and computed tomography to the diagnosis through the case of a patient previously treated for breast cancer.

Abstract: We report the case of a patient, previously treated for breast cancer, in whom echocardiography suggested the diagnosis of a cardiac tumor due the presence of a mass on the posterior mitral annulus.

Cystic adventitial disease of the popliteal artery with unusual spontaneous regression: A case report with literature review.

This report highlights the case of cystic adventitial disease of the left popliteal artery in a 45-year-old male patient. Imaging modalities confirmed the diagnosis and high resolution MRI found a cystic connection to the adjacent knee joint. The evolution was unusual with spontaneous regression of the symptoms.

Isolated Persistent Left Superior Vena Cava Revealed by an Associated Asthma.

Background: Persistent left superior vena cava (PLSVC) is a rare anomaly of the thoracic venous system. . We present a case of a patient with isolated asymptomatic PLSVC, who was diagnosed because of dyspnea revealing an associated asthma.

Distance education in times of covid 19: a leap into the future?

Introduction: Online education has grown a lot in recent months in our country during the global health crisis (COVID19). It has been widely used at all levels and fields of education ranging from elementary school to graduate and postgraduate studies. The aim of this study is to evaluate this teaching method compared to classical face-to-face teaching by referring to the learner's point of view.

A bilinear convolutional neural network for lung nodules classification on CT images.

Purpose: Lung cancer is the most frequent cancer worldwide and is the leading cause of cancer-related deaths. Its early detection and treatment at the stage of a lung nodule improve the prognosis. In this study was proposed a new classification approach named bilinear convolutional neural network (BCNN) for the classification of lung nodules on CT images.
