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.

Drainage of tuberculous pneumothorax in a Northern African country: Characteristics and difficulties.

Introduction-aim: Tuberculous pneumothorax (TP) is a serious complication of cavitary pulmonary tuberculosis. The aim of this study was to identify TP drainage characteristics and difficulties.

Methods: This was a retrospective multicenter study of patients hospitalized for TP between 1999 and 2021 in three hospitals from Tunis (Tunisia): Abderahmen Mami, La Rabta, and Charles Nicolle.

Can Coronavirus Disease 2019 Induce Sarcoidosis: A Case Report.

Since the emergence of coronavirus disease 2019, a large spectrum of clinical manifestations following this acute viral infection has been reported especially autoimmune manifestations and inflammatory disorders. However, a causal link has not yet been established. Herein, we reported a case of pulmonary mediastinal sarcoidosis following coronavirus disease 2019 infection.

Usefulness of cardiac computed tomography in prosthetic heart valve dysfunction.

Background: Prosthetic heart valve (PHV) dysfunction is a serious complication. Echocardiography remains the first-line imaging investigation to assess PHV dysfunction. However, the role of Computed Tomography (CT) scanning in this type of case has not been thoroughly studied yet.

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.

Docetaxel monotherapy induces necrotic acute pancreatitis.

Introduction: Drug-induced acute pancreatitis (AP) is uncommon and represents 0.1 to 2% of all AP cases. Chemotherapy-induced AP is very rare.

Current and new imaging techniques in risk stratification of asymptomatic severe aortic stenosis.

Aortic stenosis (AS) is one of the most common valvular diseases in clinical practice. The prevalence of calcified AS with moderate or severe stenosis exceeds 2% after 75 years. The optimal timing of intervention for asymptomatic severe AS is uncertain and controversial.

A giant calcified aneurysm of the basal inferior wall: a rare phenomenon.

Left ventricular aneurysms (LVA) are mainly a late consequence of transmural myocardial infarction. Approximately 80% of LVA are located in the anterior and/or apical walls, most commonly associated with left anterior descending artery occlusion but any region may be engaged. Basal inferior wall aneurysms are rare and constitute nearly 3% of all LVA.

Radiofrequency ablathermia of pulmonary nodules : CT follow-up and prognostic study.

Introduction: Radiofrequency ablathermia of pulmonary nodules is a local curative treatment whose efficacy assessment is still a current topic.

Aims: To specify the monitoring protocol, the scannographic aspects of treated lesions, deduce criteria of incomplete ablation, and identify the prognostic factors influencing overall and progression-free survivals.

Methods: A prognostic descriptive retrospective study conducted in the medical imaging department of Abderrahman Mami Hospital.

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.

Unusual cause of laryngeal dyspnea and swallowing troubles in a 2-year old child.

Plexiform neurofibromas are rare benign tumors developed from peripheral nervous system often associated with neurofibromatosis type 1. We report the case of multifocal plexiform neurofibromas in a 2-year-old child with cervical mass obstructing the trachea causing respiratory distress. A cervical ultrasound examination was performed followed by enhanced CT and MRI.

Deep learning-based CAD schemes for the detection and classification of lung nodules from CT images: A survey.

Background: Lung cancer is the most common cancer in the world. Computed tomography (CT) is the standard medical imaging modality for early lung nodule detection and diagnosis that improves patient's survival rate. Recently, deep learning algorithms, especially convolutional neural networks (CNNs), have become a preferred methodology for developing computer-aided detection and diagnosis (CAD) schemes of lung CT images.

Spontaneous hemothorax and neurofibromatosis type 1: How to explain it, how to explore it and how to treat it?

Neurofibromatosis type 1 (NF1), also known as Von Recklinghausen's disease is an autosomal dominant genetic disorder. It is the most common of phacomatoses. Pulmonary complications have been rarely described in the literature.

Interstitial pneumonia in a glassblower: think to chronic beryllium disease!

Chronic beryllium disease (CBD) is an occupational illness with varying severity. In this report, we describe a 27 year old man, glassblower, who developed a fatal CBD after six months of unknown Beryllium's exposure. The diagnosis was suspected on histological examination and then consolidated by confirmation of Beryllium's exposure at the working area.

Interstitial lung diseases: Imaging contribution to diagnosis and elementary radiological lesions.

Interstitial pneumonias comprise a heterogeneous group of disorders in which a multidisciplinary approach is important for accuracy in diagnosis; indeed, one might say, even mandatory. The team of collaborators should include radiologists, because high resolution computed tomography (HRCT) of the thorax is the first, and most of times, the only imaging examination to be prescribed after chest X-ray. Elementary lesions of the interstitium can be accurately described with HRCT, inasmuch as lung windowing with sharp filtering in this technique reproduces the microscopic features of the lung.

Angiofibrolipoma of Posterior Mediastinum with Transforaminal Extension.

Angiofibrolipoma is a histological variant of lipoma, which commonly occurs in subcutaneous tissues. In the present report we illustrate the case of an angiofibrolipoma of the posterior upper mediastinum in a 75-year-old man presented with progressive chest pain. Xray chest showed a homogeneous opacity vertically oriented along the right lateral aspect of thoracic vertebrae with an obtuse angle to the mediastinum.

Spontaneous Right Hemothorax in the Elderly.

Rupture of thoracic aortic aneurysm is a life threatening condition. Rupture in the right pleural cavity is extremely rare. We report the case of an 80-year-old man with a spontaneous right hemothorax.
