BACKGROUND: The management of blunt thoracic aortic injury (BTAI) has evolved radically in the last decade with changes in the processes of care and the introduction of thoracic endovascular repair (TEVAR). These changes have wrought improved outcome, but the direct effect of TEVAR on outcome remains in question as previous studies have lacked vigorous risk adjustment and long-term follow-up. To address these knowledge gaps, we compared the outcomes of TEVAR, open surgical repair, and nonoperative management for BTAI...

We report a case of a 56-year-old woman diagnosed with infiltrating ductal carcinoma of the left breast, who had undergone left modified radical mastectomy followed by radiotherapy and adjuvant chemotherapy. FDG PET-CT showed metastatic brachial plexopathy with intra-spinal and extra-axial brain metastasis. Metastatic brachial plexopathy along with brain and spinal metastasis is a rare condition with very less incidence. The scan also showed left para-sternal anterior chest wall recurrence with antero-superior mediastinal metastasis...

A computed tomography scanner first, then a magnetic resonance imaging were performed for chest pain in a 24-year-old woman allowed to find out a 5-cm long and 2-cm large right pleural tumour close to the rachis (T9 and T10) and spindle-shaped. This patient was a smoker and reported a fall down the stairs a few weeks ago. A scan-guided biopsy was decided and microscopic examination revealed a fibrous tissue in which were entrapped regular and non-suspicious alveolar glands. After elimination of differential diagnosis, the most probable hypothesis was that this lesion was due to the traumatism reported by the patient...

BACKGROUND: The detection and quantification of solid components in pulmonary subsolid nodules (SSN) are of vital importance on differential diagnosis, pathological speculation and prognosis prediction. However, no objective and wide-accepted criterion has been built up to now. The purpose of this study is to explore the optimal threshold that can be used for the detection and quantification of solid components in SSNs by using threshold segmentation method on computed tomography (CT) images...

BACKGROUND: Myocardial involvement in young adults has various causes. Acute myopericarditis is one of the myocardial involvements in young adults. It is easy to confuse with acute ST-elevation myocardial infarction because of the electrocardiographic features. This study aims to investigate a number of imaging techniques and clinical features for acute myopericarditis in young adults (<30 years of age). METHODS: This retrospective study included 147 patients selected from the 2147 patients at the age of <30 with acute chest pain admitted into emergency service between 2010 and 2016...

Brain and eye hydatid cysts are early symptomatic, as opposed to those developing in other organs, including lungs, where they remain asymptomatic through adolescence, even to adulthood, due to their slow growth. Hence, discovering that patients have lung hydatid cyst occurs, frequently, during random chest imaging. Up to thirty percent of pulmonary echinococcal cysts may rupture spontaneously, after chest or abdominal trauma. The main lung hydatidosis complaints, such as dyspnea and chest pain, are caused by the reduction of the functional area of the lung, expectoration of the tapeworm cystoides into the bronchial tree, or by compression of surrounding structures...

Computer-aided reading (CAR) of medical images is becoming increasingly common, but few studies exist for CAR in tuberculosis (TB). We designed a prospective study evaluating CAR for chest radiography (CXR) as a triage tool before Xpert MTB/RIF (Xpert).Consecutively enrolled adults in Dhaka, Bangladesh, with TB symptoms received CXR and Xpert. Each image was scored by CAR and graded by a radiologist. We compared CAR with the radiologist for sensitivity and specificity, area under the receiver operating characteristic curve (AUC), and calculated the potential Xpert tests saved...

A 57 year old man was referred from an outside facility for an unresolving pneumonia. Imaging of the chest demonstrated a right lung mass with a consolidation in the middle lobe, pleural effusion, and mediastinal lymphadenopathy. Cytologic examination of cultures from the bronchoscopy and thoracentesis did not yield a definitive diagnosis. Video-assisted thoracoscopic surgery (VATS) was performed because of a retained hemothorax and a suggestive lesion. Biopsy specimens obtained during VATS were consistent with mucormycosis...

OBJECTIVES: Reductions in diaphragm activity are associated with the postoperative development of atelectasis. Neostigmine reversal is also associated with increased atelectasis. We assessed the effects of neostigmine, sugammadex, and spontaneous reversal on regional lung ventilation and airway flow. METHODS: Six Sprague-Dawley rats were paralysed with rocuronium and mechanically ventilated until recovery of the train-of-four ratio to 0.5. We administered neostigmine (0...

We present the case of an adult patient with active post-primary pulmonary tuberculosis (TB) and discuss specific morphological and textural aspects found at high-field magnetic resonance imaging (MRI) of the lung. The 42-year-old man, heavy smoker, undertook a routine employment medical examination and was admitted to a referral pulmonology and TB center due to the abnormal findings seen on his chest radiography. The patient presented nonspecific symptoms, bilateral bronchial breath at pulmonary auscultation, inflammatory syndrome on the laboratory blood tests and positive sputum smears for acid-fast bacilli, which together with the typical aspect on the chest radiography lead to a diagnosis of post-primary pulmonary TB and administration of specific medication...

Recurrent respiratory papillomatosis (RRP) is a disease of the respiratory tract caused by infection with the human papillomavirus (HPV) and is characterized by multiple recurring papillomas throughout the respiratory tract. Although rare, extra laryngeal involvement carries the risk of malignant transformation in 3-7% of adults. We report the case of a patient with unmonitored juvenile onset RRP with pulmonary involvement found to have malignant transformation to squamous cell carcinoma (SCC). Incidentally found on chest radiography for mild chest wall trauma, she was found to have a large left lower lobe mass with pathology consistent with SCC...

We report an initial investigation of a subtraction-based method to estimate right ventricle ejection fraction (RVEF) from ECG-gated planar equilibrium radionuclide angiography (ERNA) data. Twenty-six consecutive patients referred for scintigraphic evaluation of cardiac function prior to chemotherapy had ECG-gated first-pass (FP) imaging and ERNA imaging performed following the same radiotracer injection. RVEF was computed from FP images (RVEFFP) and separately from ERNA images (RVEFERNA). Standard methods for computing ejection fractions were used to obtain RVEFFP values...

CASE: A 44-year-old man intentionally stabbed himself in the anterior neck and left thorax with a fruit knife. Physical examination revealed two open wounds entering the thoracic cavity in the front chest, and a stab wound entering the trachea at the neck. Two chest tubes were initially inserted for the left lung injury with open hemopneumothorax. Nevertheless, the worsening oxygenation required positive pressure ventilation (PPV) with endotracheal intubation. OUTCOME: Right hemiparesis was found during weaning from PPV...
