Radiographic features. Cardiac silhouette refers to the outline of the heart as seen on frontal and lateral chest radiographs and forms part of the cardiomediastinal contour.. CNS. It is almost always caused by a pathologic airspace/alveolar process, in which something other than air fills the alveoli. upper limb: 15-25%. from joint: 5-10%. Evaluate the hila for lymphadenopathy, calcifications, and masses.The left hilum is normally higher than the right. Differential diagnosis. vascular occlusion due to angioinvasive aspergillosis).. It is classified as a subtype of interstitial lung disease. Asbestosis typically occurs 10-15 years following the commencement of exposure to asbestos and is dose related 3.Heavy asbestos exposure is predominantly encountered among men, as most exposures are occupational in the setting of construction, mining, or ship/automotive industries. Endotracheal tubes (ETT) are wide-bore plastic tubes that are inserted into the trachea to allow artificial ventilation. Lung metastases are common. Some of the more common accessory fissure include 1:. Amiodarone lung is an interstitial lung disease seen in patients being administered the cardiac drug amiodarone and can manifest in a number of histopathologic patterns. In all cases, respiratory bronchiolitis-interstitial lung disease is typically associated with heavy tobacco smoking (usually of 30 pack-years or more) and is often seen in young middle-aged patients (30-40 years of age).. Clinical presentation. Cannonball metastases refer to multiple large, well-circumscribed, round pulmonary metastases that appear not unsurprisingly like cannonballs. The differential attenuation of x-ray photons by two adjacent structures defines the silhouette, e.g. Lung atelectasis (plural: atelectases) refers to collapse or incomplete expansion of pulmonary parenchyma. There are two major types of cardiac conduction devices: pacemakers and automatic implantable cardioverter-defibrillators tuberculous peritonitis may also give this appearance. The cervicothoracic sign is a variation of the silhouette sign on frontal chest radiography used to determine whether a superior (para)mediastinal soft tissue mass is anterior or posterior to the trachea.. A positive cervicothoracic sign occurs when a thoracic lesion contacts the neck or extends into it, thereby obliterating the upper borders of the lesion on A complete version of the work and all supplemental materials, including a copy of the permission as stated above, in a suitable standard electronic format is deposited immediately upon initial publication in at least one online repository that is supported by an academic institution, scholarly society, government agency, or other well-established organization that Epidemiology. The most common cause is metastases from ovarian, gastric, or colon cancer. Right middle lobe collapse (or simply termed middle lobe collapse) has distinctive features, but can be subtle on frontal chest radiographs. It is one of the many patterns of lung opacification and is equivalent to the pathological diagnosis of pulmonary consolidation.. It is usually visible on standard CT, however, it is best seen on HRCT chest. This article will broadly discuss all the histological subtypes as a group, focusing on Individual lobes of the lung may collapse due to obstruction of the supplying bronchus. Synovial sarcoma is one of the (less common) causes of cannonball metastases to the lung. Great vessels / gastric bubble. Silhouette sign is somewhat of a misnomer and in the true sense actually denotes the loss of a silhouette, thus, it is sometimes also known as loss of silhouette sign or loss of outline sign 4.. pulmonary valve stenosis; pulmonary arterial hypertension; atrial septal defect (ASD) ventricular Tree-in-bud sign is not generally visible on plain radiographs 2.. The most common cause is metastases from ovarian, gastric, or colon cancer. Air space opacification is a descriptive term that refers to the filling of the pulmonary tree with material that attenuates x-rays more than the surrounding lung parenchyma.. The gastric bubble should be seen clearly and not displaced.. Hila and mediastinum. The aortic knob should be clearly seen. Location. Lobar collapse refers to the collapse of an entire lobe of the lung. Lung cancer (primary lung cancer), or frequently if somewhat incorrectly known as bronchogenic carcinoma, is a broad term referring to the main histological subtypes of primary lung malignancies that are mainly linked with inhaled carcinogens, with cigarette smoke being a key culprit. The incidence of synchronous lung metastasis at initial cancer presentation is about 18 per 100,000, noting this figure does not include metachronous metastases (occurring after initial cancer staging) 8.The incidence is slightly higher in males (20 in 100,000) than females (16 in 100,000) 8.The specific As such it is a subtype of atelectasis (collapse is not entirely synonymous with atelectasis, which is a more generic term for 'incomplete expansion'). On imaging, they have a variety of Right ventricular enlargement (also known as right ventricular dilatation (RVD)) can be the result of a number of conditions, including:. azygos fissure: most commonly seen accessory fissure; inferior accessory fissure head and neck: 5%. by fluid) and thus Interstitial lung disease (ILD) is an umbrella term that encompasses a large number of disorders that are characterized by diffuse cellular infiltrates in a periacinar location.The spectrum of conditions included is broad, ranging from occasional self-limited inflammatory processes to severe debilitating fibrosis of the lungs. Radiographic features. enteric - enteric adenocarcinoma of the lung / primary pulmonary enteric adenocarcinoma; Epidemiology. Accessory fissures of the lung usually occur at the borders of bronchopulmonary segments.They are common normal variants but are less commonly seen on imaging. A core biopsy may be helpful if the primary tumor is unknown. Bronchiectasis (plural: bronchiectases) is defined as an irreversible abnormal dilatation of the bronchial tree. For a general discussion please refer to the article on lobar collapse. Lobar consolidation is the term used to describe consolidation in one of the lobes of the lung. It infers an alveolar spread of disease and is most commonly due to pneumonia. Usual interstitial pneumonia (UIP) is a histopathologic and radiologic pattern of interstitial lung disease, which is the hallmark pattern for idiopathic pulmonary fibrosis (IPF).. On imaging, usual interstitial pneumonia usually presents with a lung volume loss and an apicobasal gradient of peripheral septal thickening, bronchiectasis, and honeycombing. Pulmonary edema is a broad descriptive term and is usually defined as an abnormal accumulation of fluid in the extravascular compartments of the lung 1. heart borders against the adjacent lung segments, and it is the pathological Pulmonary edema is a broad descriptive term and is usually defined as an abnormal accumulation of fluid in the extravascular compartments of the lung 1. It is now considered the most common histological subtype in terms of prevalence, causing 38.5% of all cases 9. They may be inserted by medical, surgical, anesthetic/ICU, or radiology specialists. Epidemiology. Air bronchograms will not be visible if the bronchi themselves are opacified (e.g. Epidemiology. lymphoma can present as omental caking, diffuse peritoneal thickening, and ascites, the best clue is significant lymphadenopathy Implantable cardiac conduction devices (also known as cardiac implantable electronic devices or CIEDs) are a very common medical device of the thorax, with over one million implanted in the United States of America alone.. Differential diagnosis. Round atelectasis, also known as rounded atelectasis, folded lung or Blesovsky syndrome, is an unusual type of lung atelectasis where there is infolding of a redundant pleura. The neonatal chest radiograph in the exam setting may strike fear into the heart of many radiology registrars, but it need not! It can occur in a variety of settings, including: trauma; osteoporosis; Langerhans cell histiocytosis (LCH) from soft tissues: 90-95%. Renal cell carcinomas (RCC) (historically also known as hypernephroma or Grawitz tumor) are primary malignant adenocarcinomas derived from the renal tubular epithelium and are the most common malignant renal tumor.They usually occur in 50-70-year old patients and macroscopic hematuria occurs in 60% of the cases. The French terms "envole de ballons" and "lcher de ballons", which translate to "balloons release", are also used to describe this same appearance.Metastases with such an appearance are classically secondary to 1,2: Pathology. Central venous catheters (CVC), also known as central venous lines (CVL), refer to a wide range of catheters that are inserted so that their distal tips lie in a central vein.Central venous access devices can broadly be divided into four categories. Terminology. A core biopsy may be helpful if the primary tumor is unknown. In general, patients are young and are diagnosed before the age of 40 years 9.. Check aortic size and shape and the outlines of pulmonary vessels. tongue: rare 9 (synovial sarcoma of the tongue) conjunctiva 3. It is considered the most common cause of Although uncommon, it can be seen along with several other described signs of pulmonary Typically the centrilobular nodules are 2-4 mm in diameter and peripheral, within 5 mm of the pleural surface. Clinical presentation. Pathology extremities: 80-95% 1. lower limb: 60-70%. In general, patients are young and are diagnosed before the age of 40 years 9.. Presentation tends to be with progressive shortness of breath and chronic cough 4.Inspiratory crackles are It has a variety of underlying causes, with a common etiology of chronic inflammation. This entity is most commonly encountered in patients with longstanding asthma, and only occasionally in patients with cystic fibrosis 4,5.. Only rarely does it appear in patients with no other identifiable pulmonary illness 5.. Vertebra plana (plural: vertebrae planae), also known as the pancake, silver dollar or coin-on-edge vertebra, is the term given when a vertebral body has lost almost its entire height anteriorly and posteriorly, representing a very advanced compression fracture.. The disease occurs in two clinical forms that are subdivided by their temporal relationship to the exposure to silica: acute silicosis: manifests as alveolar silicoproteinosis classic silicosis: manifests as a chronic interstitial reticulonodular disease The classic form is much more common than the acute form and can be classified as simple or In radiological studies, it presents as increased attenuation of the It is considered the most common cause of lymphoma can present as omental caking, diffuse peritoneal thickening, and ascites, the best clue is significant lymphadenopathy Epidemiology. Hampton hump refers to a dome-shaped, pleural-based opacification in the lung most commonly due to pulmonary embolism and lung infarction (it can also result from other causes of pulmonary infarction (e.g. Epidemiology. This entity is most commonly encountered in patients with longstanding asthma, and only occasionally in patients with cystic fibrosis 4,5.. Only rarely does it appear in patients with no other identifiable pulmonary illness 5.. The system is similar to the Fleischner criteria but designed for the subset of patients intended for low-dose The size and shape of the cardiac silhouette provide useful clues for underlying disease. Lymphocytic interstitial pneumonitis is a benign lymphoproliferative disorder characterized by lymphocyte predominant infiltration of the lungs. Tubes come in a variety of sizes and have a balloon at the tip to ensure that gastric contents are not aspirated into the lungs.Adult tubes are usually approximately 1 cm in diameter. From the frontal projection, the cardiac silhouette can be divided into right and left borders: Lung-RADS (Lung Imaging Reporting and Data System), is a classification proposed to aid with findings in low-dose CT screening exams for lung cancer.The goal of the classification system is to standardize follow-up and management decisions. tuberculous peritonitis may also give this appearance.
