Stefania Zerbo
The commonest cause of blunt cardiac injuries is from traffic accidents followed by violent falls, sport activities, accidents or a fight but rupture of the heart is rare and lethal. The precise incidence of cardiac injury after a blunt chest trauma is unknown as rates vary greatly in the literature from between 7% and 76% of cases. Autopsy studies have shown that the right ventricle is the most frequently ruptured, followed by the left ventricle, right atrium, intraventricular septum, left atrium and interatrial septum with decreasing frequency...

Background: Imaging has a big role in tuberculosis (TB) diagnosis and chest X-ray is preferable because it is available in primary health care and can point out the location, area, and morphology of lesions, such as cavity, consolidation, pleural effusions, and fibrosis. We aimed to compare the chest X-ray findings in multi-drug resistant TB (MDR-TB) and in drug-sensitive TB (DS-TB) cases. Methods: This is a retrospective cross-sectional study which compares chest X-ray findings of two groups of patients, involving 183 DS-TB patients and 183 MDR-TB patients...

Introduction Growing evidence supports ischemia-guided management of chest pain, with invasive and non-invasive tests reliant upon achieving adenosine-induced coronary hyperemia (defined as increased blood flow to an organ's perfusion bed). In the non-invasive setting, surrogate markers of hyperemia, such as increases in heart rate, are often used, despite not being formally validated. We tested whether heart rate and other non-invasive indices are reliable markers of coronary hyperemia. Methods The first part involved Doppler flow-based validation of the best pressure-wire markers of hyperemia in 53 patients...

Pulmonary artery sarcomas (PAS's) are extremely rare malignant tumors that arise from the endothelial lining of the pulmonary arteries. On CT scans PAS's appear as intraluminal filling defects in the pulmonary arteries, mimicking pulmonary embolism (PE). Due to the similarities in radiographic features as well as in clinical presentation, PAS's are usually misdiagnosed as pulmonary embolism. Since PASs are F-18 FDG avid, F-18 FDG PET/CT scan is a useful imaging tool for differentiating between these two conditions, as shown in this case report...

Pulmonary alveolar microlithiasis (PAM) is a rare autosomal recessive disease characterized by the formation of calcium phosphate microliths in the alveoli. Mutations in the gene encoding the solute carrier family 34 member 2 gene are considered to be involved in the pathogenesis of PAM. Although PAM can develop in children, the majority of patients with PAM are diagnosed in adulthood due to the slow progressive nature of the disease within the lungs. In childhood, the majority of patients with PAM are asymptomatic and changes in the lung parenchyma are usually identified incidentally...

Injuries of the supra-aortic trunk after blunt chest trauma are rare. This is a case report of a blunt traumatic lesion of the innominate artery (IA) origin that exhibited aortic arch involvement with a focus on imaging and treatment. A 41-year-old fisherman presented an IA injury secondary to a high-impact blunt chest trauma. Upon physical examination, vital signs were stable and upper extremity pulses were present. In addition to several bone fractures (costal ribs, clavicle, scapula, temporal, maxillary, and sphenoid), computed tomography angiography revealed dissection/pseudoaneurysm of the IA sparing the bifurcation...

Pericardial cysts are rare benign anomalies generally discovered as incidental findings on radiographic images. Rarely, pericardial cysts cause symptoms and may lead to complications. A 56-year-old woman presented to the emergency department for mild chest pain. A cardiovascular and respiratory examination revealed no abnormalities, while a chest X-ray and subsequent thoracic computed tomography (CT) showed a pericardial cyst. The patient refused both percutaneous treatment and thoracic surgery. Three years later, a thoracic CT scan showed that the pericardial cyst had disappeared...

The patient was a 69-year-old male who had started experiencing acute-onset pain in both shoulder joints and edema of both hands and feet. His symptoms progressively worsened within 1 month. Laboratory data indicated elevated CRP and erythrocyte sedimentation rate despite the normal range of antinuclear antibodies and rheumatoid factor and normal organ function. Furthermore, imaging data of the hand indicated synovitis without bone erosions. Meanwhile, chest CT revealed a lung tumor, leading to a diagnosis of primary lung adenocarcinoma with EGFR mutation (cT2aN3M0, stage IIIB)...
