BACKGROUND: Pericardial agenesis is a rare congenital heart disease characterized by a variable clinical presentation. CASE SUMMARY: A 32-year-old man was sent by an occupational health physician to our health care centre because of pathological electrocardiogram (ECG). On transthoracic echocardiogram, we had some difficulty to obtain a good quality of four-chamber apical view that was shifted upper and laterally towards the left anterior axillary line. Nonetheless, an abnormal diastolic expansion of the apex of the left ventricle (LV) that had an otherwise normal systolic function was detected...

Hyperpolarized 129 Xe gas MRI is an emerging technique to evaluate and measure regional lung function including pulmonary gas distribution and gas exchange. Chest computed tomography (CT) still remains the clinical gold standard for imaging of the lungs, though, in part due to the rapid CT protocols that acquire high-resolution images in seconds and the widespread availability of CT scanners. Quantitative approaches have enabled the extraction of structural lung parenchymal, airway and vascular measurements from chest CT that have been evaluated in many clinical research studies...

INTRODUCTION: We present a narcolepsy type 1 patient that develop an autoimmune encephalitis post vaccine and/or a SARS-CoV-2 infection. CASE REPORT: At 23 years old, the patient was referred to the emergency room with difficult speaking, headache and tremor followed by changes in behavior, autonomic dysfunction, right focal motor seizure and lethargy. He has received seven weeks before mRNA-1273 (Moderna) vaccine followed by a SARS-CoV-2 infection four weeks after vaccination (positive antigen test)...

Cancer of the penis is a rare tumor that occurs in the elderly. Because of its rarity, it is often not diagnosed early, and its treatment poses difficulties for practicing oncologists. We report the case of an elderly patient treated for locally advanced squamous cell carcinoma (SCC) of the penis, with a review of the literature. A 71-year-old man, who had been complaining of pruritus on the penis two years ago, presented with an ulcerated lesion on the prepuce and the glans. A biopsy of the lesion with pathological study showed a SCC of the penis...

Background Clinical presentation, diagnosis, and treatment of myocarditis in children can be highly challenging, and results can vary greatly. Research on the precise processes of myocardial injury, including the effects of viral infections and newly identified variables like COVID-19, is still underway. Though treatment approaches, such as immunosuppressive therapy, are still debatable, diagnostic methods such as cardiac MRI and biomarkers show promise in improving diagnostic accuracy. The purpose of this study is to describe the spectrum of pediatric acute myocarditis, assess existing therapy approaches, and develop regional guidelines based on the experience of a tertiary care institution...

The aim of this retrospective study was to identify myocardial injury after COVID-19 inflammation and explore whether myocardial damage could be a possible cause of the persistent symptoms following COVID-19 infection in previously healthy individuals. This study included 139 patients who were enrolled between January and June 2021, with a mean age of 46.7 ± 15.2 years, of whom 68 were men and 71 were women without known cardiac or pulmonary diseases. All patients underwent clinical work-up, laboratory analysis, cardiac ultrasound, and CMR on a 1...

Prostatic malakoplakia (PMP) is a rare inflammatory disease, and misdiagnosis on imaging is a major reason for unnecessary punctures; however, information on imaging is even rarer. Five patients with PMP between May 2022 and February 2023 were enrolled in this study to summarize the imaging manifestations. All patients underwent ultrasound (US)-guided prostate biopsy and were confirmed by pathology, and the presence of prostate cancer was also excluded by pathology. The five patients, with a median age of 71 years (range = 58-74 years), had a median total prostate-specific antigen (T-PSA) of 10...

BACKGROUND: Anomalous aortic origin of a coronary artery from the opposite sinus is a rare congenital abnormality that may be encountered during primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). CASE SUMMARY: A 65-year-old man presented with chest pain and signs of heart failure. Electrocardiogram demonstrated atrial fibrillation with ST elevation in the high lateral leads, and he was taken emergently to the cardiac catheterization laboratory for primary PCI...

OBJECTIVE: This study aimed to investigate the utility of CT quantification of lung volume for predicting critical outcomes in COVID-19 patients. METHODS: This retrospective cohort study included 1200 hospitalised patients with COVID-19 from 4 hospitals. Lung fields were extracted using artificial intelligence-based segmentation, and the percentage of the predicted (%pred) total lung volume (TLC (%pred)) was calculated. The incidence of critical outcomes and posthospitalisation complications was compared between patients with low and high CT lung volumes classified based on the median percentage of predicted TLCct (n=600 for each)...

Lymphatic malformations frequently present as benign masses in the neck and clavicle region among infants and young children. Cystic hygroma represents an often-encountered form of lymphatic malformation. This case report details the medical history of a one-year-old girl characterized by a multifaceted medical background, initially exhibiting symptoms of persistent cough, cold, and neck swelling. Further investigations revealed more severe conditions: complex congenital heart defects, including large atrial septal defect (ASD), large ventricular septal defect (VSD), and aorta arising from the right ventricle with cystic hygroma and annular pancreas...

INTRODUCTION: Primary chest wall tumors arise from muscle, fat, blood vessels, the nerve sheath, cartilage, or bone of the chest wall. One of the chest wall sarcomas is Ewing Sarcoma (ES), first described in 1921 by James Ewing, which is a highly aggressive bone and soft-tissue cancer. This case report aimed to present an Ewing Sarcoma with intra thoracic and multiple extra thoracic metastases in young adult male patient. PRESENTATION OF CASE: We describe a unique case of metastatic of ewing's sarcoma in a 23-year-old male that showed a mass on the right lower posterior lung with pleural effusion, which was initially thought to be lung tumor that metastasized to the pleura...

We present a case of a young patient with chest pain. Labs and cardiac imaging were suspicious for acute myocarditis. Genetic testing revealed a diagnosis of desmoplakin cardiomyopathy. Desmoplakin cardiomyopathy may be considered in patients with recurrent acute myocarditis or a family history of cardiac disease to avoid the potential for misdiagnosis.

BACKGROUND: Patients with congenital myopathies may experience respiratory involvement, resulting in restrictive ventilatory dysfunction and respiratory failure. Pulmonary hypertension (PH) associated with this condition has never been reported in congenital ryanodine receptor type 1(RYR1)-related myopathy. CASE PRESENTATION: A 47-year-old woman was admitted with progressively exacerbated chest tightness and difficulty in neck flexion. She was born prematurely at week 28...

PURPOSE: This study aims to highlight presentations, acute findings and imaging phenotypes of patients presenting to the emergency department (ED) within 30 days of a transcatheter aortic valve replacement (TAVR). METHODS: A retrospective review of patients diagnosed with aortic valve disease who underwent a TAVR between Jan 2015 and Nov 2021 at a large academic medical center was completed. From an initial 1271 patients, 146 were included based on their presentation to the ED within 30 days post-TAVR procedure...

A 74-year-old man was suffering from nine months of perineal pain and progressive worsening of urinary symptoms including nocturia and urgency. His prostate-specific antigen (PSA) levels were 1.48 ng/mL at the time of referral. Initially, a differential diagnosis of prostatitis or seminal vesicle inflammation was made, and four weeks of antibiotics were prescribed, which were later extended to six weeks due to failure of symptoms to resolve. Magnetic resonance imaging (MRI) of the prostate was then conducted...

A myocardial diverticulum is a rare congenital anomaly characterized by pouch-like protrusions within the myocardial wall, which can potentially lead to various cardiac complications. This case report describes a unique presentation of a left ventricular diverticulum (LVD) with an associated apical thrombus, highlighting the diagnostic and management challenges posed by this condition. A 58-year-old man presented to the emergency department with left arm weakness, wrist drop, and chest pain, initially raising concerns for a stroke...

BACKGROUND: We present a case of a pregnant patient with recurrent angina, in which her symptoms were initially attributed to coronary artery spasm. However, during follow-up, she was diagnosed as having pheochromocytoma, a rare neuroendocrine tumour. CASE SUMMARY: The 35-year-old patient was admitted to the hospital because of chest pain and elevated cardiac troponins after the use of MDMA. Physical examination, electrocardiogram, echocardiography, coronary angiogram, and cardiac MRI were normal...

KEY CLINICAL MESSAGE: Plasma cell myeloma is a rare entity in the pediatric population. The peak incidence is in the seventh decade, with less than 2% of cases occurring in patients under the age of 40. It is worth noting that any destructive bony lesion in a child should be investigated. ABSTRACT: Plasma cell myeloma (multiple myeloma) is the most common form of plasma cell neoplasm. It is a rare entity in young patients. The peak incidence is in the seventh decade, with less than 2% of cases occurring in patients under the age of 40...

Venous malformations (VMs) located in the anterior mediastinum are rare. Thus, diagnosis using imaging is often challenging, and they are typically diagnosed only after total tumor resection. Herein, we report a case of VM located in the anterior mediastinum diagnosed using computed tomography (CT) and magnetic resonance imaging (MRI). A 56-year-old woman presented for further evaluation of an anterior mediastinal mass observed during a chest CT. On CT, the mass was observed to have scattered calcifications and early and persistent enhancement with contrast material pooling dorsally in the delayed phase...

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous syndrome that is poorly defined, reflecting an incomplete understanding of its pathophysiology. AIM: To redefine the phenotypic spectrum of HFpEF. METHODS: The PACIFIC-PRESERVED study is a prospective multicentre cohort study designed to perform multidimensional deep phenotyping of patients diagnosed with HFpEF (left ventricular ejection fraction≥50%), patients with heart failure with reduced ejection fraction (left ventricular ejection fraction≤40%) and subjects without overt heart failure (3:2:1 ratio)...
