We report a 57-year-old man presenting with symptoms of sharp pricking, exertional retrosternal chest pain multiple times, each episode lasting for a few seconds. On evaluation, the ECG of the patient showed normal sinus rhythm with T wave inversions in leads V1-V3. Troponin T test was negative. Transthoracic echocardiography showed a globular mass in the interventricular septum. Cardiac MRI was suspicious of the lesion to be a hydatid cyst. Surgical excision of the lesion followed by histopathology was confirmatory of hydatid cyst...

INTRODUCTION: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited myocardial disease with an elusive association with myocardial inflammation. A myocarditis phenotype has been well established without systematic evidence of a viral trigger. We intend to study the relationship between myocardial inflammation detected by Cardiac magnetic resonance (CMR) and ARVC in a paediatric population. METHODS: Retrospective case series of all patients <18 years admitted to two CMR units for clinical suspicion of myocarditis from March 2012 to June 2017 who had genetic testing for inherited cardiomyopathies including analysis for known ARVC genes...

A 41-year-old woman was visiting Oxford, where she had a sudden cardiac arrest. Cardiopulmonary resuscitation was started by a bystander until the paramedics arrived, who found her in ventricular fibrillation, and delivered three shocks. After 28 min she had return of spontaneous circulation. Emergency coronary angiography revealed normal coronary arteries. Echocardiography followed by a cardiac MRI showed non-dilated left ventricles with no evidence of late gadolinium enhancement. She had a single-chamber implantable-cardioverter defibrillator (ICD)...

We report a rare case of a mediastinal malignant granular cell tumor in a 41-year-old man presenting with dyspnea, retrosternal chest pain, and recurrent pericardial effusion under treatment with corticosteroids. Because of recurrent episodes, further investigations with chest MRI and F-FDG PET/CT revealed a large infiltrating and strongly hypermetabolic mass in the mediastinum with pericarditis. Histopathology and immunohistochemical analysis showed large cells with greater pleomorphism and eosinophilic granular cytoplasm with positive staining for S100 protein and CD68 as well as high Ki67 proliferative index (15%) confirming the diagnosis of a malignant granular cell tumor...

Introduction: Brown-Séquard Syndrome (BSS) is one of the rarest incomplete spinal cord syndromes. The combination of injuries to peripheral nerves and the central nervous system result in an array of symptoms that can result in overlapping clinical presentations and delayed diagnosis. Early detection of spinal cord injury in patients with peripheral nerve injury has been observed to have a positive effect on outcomes. Case presentation: This report discusses the case of a 29-year-old male patient with Brown-Sequard-Plus Syndrome (BSPS) and Brachial Plexopathy (BP) secondary to gunshot wound in the left inferior neck...

BACKGROUNDS: Whole-body bone scintigraphy (WBBS) and MRI are widely used in assessment of patients with synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome. However, the value of F-18 fluorodeoxyglucose-positron emission tomography/computed tomography (18 F-FDG PET/CT) in SAPHO syndrome was unclear. The aim of this study was to characterize the manifestation of SAPHO syndrome on 18 F-FDG PET/CT and explore its relationship with clinical symptoms and WBBS. METHODS: Twenty-six patients who suffered from SAPHO syndrome and had undergone whole-body 18 F-FDG PET/CT were recruited in Peking Union Medical College Hospital from 2004 to 2016...
