The aim was to compare computed tomography (CT) features in acute and chronic aortic dissections (AADs and CADs) and determine if a certain combination of imaging features was reliably predictive of the acute versus chronic nature of disease in individual patients. Consecutive patients with aortic dissection and a chest CT scan were identified, and 120 CT scans corresponding to 105 patients were reviewed for a variety of imaging features. Statistical tests assessed for differences in the frequency of these features...

Introduction: Retrosternal goiter refers to any thyroid enlargement in which over 50% of the thyroid permanently located under the thoracic inlet or the lower pole of thyroid is not palpable with the neck in hyperextended position. Due to the increasing number of surgical procedures of retrosternal goiter, the present study was carried out to examine the symptoms, diagnosis, treatment, and treatment complications in retrosternal goiter patients. Materials and Methods: Data related to demographic data (age and gender), clinical symptoms (dyspnea, dysphagia, dysphonia, lumps in neck, and hoarseness), methods of diagnosis (computed tomography [CT], chest X-ray [CXR], ultrasonography, and magnetic resonance imaging), and postoperative complications (bleeding, early and late dysphonia, early and late dyspnea, transient and permanent hypocalcemia, transient, and permanent recurrent laryngeal nerve paralysis) were collected...

BACKGROUND: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital coronary anomaly. The enlarged right coronary artery provides retrograde collaterals to supply the left ventricle then preferentially directs into the lower pressure pulmonary artery system causing coronary steal phenomenon. Few patients who survive through adulthood without surgery must have abundant, well-formed functioning collaterals with adequate perfusion of the left ventricle...

Background and aims In functional chest pain (FCP) of presumed esophageal origin central nervous system hyperexcitability is generally believed to play an important role in pain pathogenesis. However, this theory has recently been challenged. Using magnetic resonance diffusion tensor imaging, the aim was to characterize any microstructural reorganization of the pain neuromatrix in FCP patients. Methods 13 FCP patients and 20 matched healthy controls were studied in a 3T MR scanner. Inclusion criteria were relevant chest pain, normal coronary angiogram and normal upper gastrointestinal evaluation...

OBJECTIVE: chest computed tomography (CT) images and their quantitative analyses have become increasingly important for a variety of purposes, including lung parenchyma density analysis, airway analysis, diaphragm mechanics analysis, and nodule detection for cancer screening. Lung segmentation is an important prerequisite step for automatic image analysis. We propose a novel lung segmentation method to minimize the juxta-pleural nodule issue, a notorious challenge in the applications...

A 21 year old male with no relevant medical history presented to our Institution for further assessments of a right paracardiac mass founded on a chest X-ray. Chest computed tomography revealed a wide median defect of the diaphragm at the level of xiphoid process of the sternum, with the herniation of omental fat tissue in the mediastinum. Cardiac magnetic resonance confirmed the presence of a huge hernia originating from the foramen of Morgagni (sterno-costal hiatus), displacing the heart leftwards and posteriorly and compressing the right ventricle (RV), giving to it a tubular shape...

OBJECTIVES: This study sought to compare early emergency department (ED) use of coronary computed tomography angiography (CTA) and stress echocardiography (SE) head-to-head. BACKGROUND: Coronary CTA has been promoted as the early ED chest pain triage imaging method of choice, whereas SE is often overlooked in this setting and involves no ionizing radiation. METHODS: The authors randomized 400 consecutive low- to intermediate-risk ED acute chest pain patients without known coronary artery disease and a negative initial serum troponin level to immediate coronary CTA (n = 201) or SE (n = 199)...

Chest radiographs are obtained as a standard part of clinical care. Rapid advancements in medical technology have resulted in a myriad of new medical devices, and familiarity with their imaging appearance is a critical yet increasingly difficult endeavor. Many modern thoracic medical devices are new renditions of old designs and are often smaller than older versions. In addition, multiple device designs serving the same purpose may have varying morphologies and positions within the chest. The radiologist must be able to recognize and correctly identify the proper positioning of state-of-the-art medical devices and identify any potential complications that could impact patient care and management...

Osteochondroma is the most common benign bone tumor but it rarely arises from the scapula. Scapulothoracic bursitis is quite rare and osteochondroma is one of the unusual causes of this condition. Synovial chondromatosis may occur extremely uncommonly in this bursa. We reported an unusual case of scapulothoracic bursitis with synovial chondromatosis which is caused by osteochondroma. To the best of our knowledge, there is no defined chondromatosis in the scapulothoracic bursa secondary to scapular osteochondroma in the literature...

Leiomyoma of uterine origin is a common histologically benign neoplasm in women; however, growth intravenously with intracardiac extension is a rare phenomenon. This is a diagnostic challenge that can present with varied clinical manifestations and multiple differential diagnosis. This is a case of a 45-year-old female patient with chest heaviness and an intracardiac mass on 2-dimensional (2D) echocardiogram. Previous history of hysterectomy was likewise noted. Imaging workup, including 2D echocardiogram and contrast-enhanced chest and abdomen computed tomography scans, was performed which demonstrated a large, heterogeneous, elongated filling defect in the right atrium and right ventricle extending to the inferior vena cava, left renal vein, and left gonadal vein...

Primitive neuroectodermal tumor is a high-grade malignant tumor originating from the neural crest and neuroectoderm, which can be subdivided into central and peripheral categories. Peripheral primitive neuroectodermal tumor is thought to be identical to Ewing's sarcoma, and falls under a broader category of Ewing's sarcoma family of tumors. Very rarely, it may present without osseous involvement, known as extraosseous Ewing's sarcoma. Here we present a case of a 38-year-old woman, who presented with several-month history of a slow-growing chest wall mass, initially thought to be a breast mass...

Although the lung is a common site for metastatic disease from extrathoracic malignancies, a pattern of lepidic growth of these metastases is considered rare. A 67-year-old man with a history of partial hepatectomy for hepatocellular carcinoma (HCC) presented to our hospital with dyspnea and a nonproductive cough. Chest radiographs and computed tomography imaging demonstrated consolidation in the right upper lobe and an ipsilateral pleural effusion. Findings were initially suspected to be secondary to infection, given the radiographic appearance and the rapid development from a normal computed tomography 3 months previously...

RATIONALE AND OBJECTIVES: Chest tomosynthesis has been suggested as a suitable alternative to CT for follow-up of pulmonary nodules. The aim of the present study was to investigate the possibility of detecting pulmonary nodule growth using chest tomosynthesis. MATERIALS AND METHODS: Simulated nodules with volumes of approximately 100 mm3 and 300 mm3 as well as additional versions with increasing volumes were created. The nodules were inserted into images from pairs of chest tomosynthesis examinations, simulating cases where the nodule had either remained stable in size or increased in size between the two imaging occasions...
