Parasitic infections of the lung occur worldwide among both immunocompetent and immunocompromised patients and may affect the respiratory system in a variety of ways. Late radiological findings result from unresolved acute RP. The classic form is much more common than the acute form and can be classified as simple or complicated, according to the radiographic findings: simple silicosis: pattern of small and round or irregular opacities, complicated silicosis: large conglomerate opacities that equate to progressive massive fibrosis.

In approximately a third of patients, the presentation may mimic pulmonary infection 6. It is thought to have been initially described by Katzenstein and Fiorelli in 1994 14. Heavy asbestos exposure is predominantly encountered among men, as most exposures are occupational in the setting of construction, mining, or ship/automotive industries. Radiographic findings on chest x-ray can consist of bilateral consolidation and/or ground-glass opacities, which tend to appear in perihilar regions. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Weerakkody Y, Bell D, et al. a perilobular pattern with ill-defined linear opacities that are thicker than the thickened interlobular septa and have an arcade or polygonal appearance. As is the case with other drug-induced pulmonary toxicity, amiodarone can cause a variety of histopathologic patterns including 6,7: A distinctive feature of amiodarone lung is the presence of foamy histiocytes which contain intracytoplasmic osmiophilic lamellar bodies. Only rarely does it appear in patients with no other identifiable pulmonary illness 5. Multiple patchy lung opacities is a pattern seen in a wide variety of conditions ( Table 50.2 ). Arch. Early in the disease chest x-rays will appear normal, or only demonstrate changes of asthma. Chest. On pixel-wise explanations for non-linear classifier decisions by layer-wise relevance propagation. It is named because this sign resembles a reverse S shape, and is therefore sometimes referred to as the reverse S-sign of Golden.. Focal airspace disease. Nonspecific interstitial pneumonia with fibrosis: radiographic and CT findings in seven patients. Radiographics. Prone thin-section imaging through the lung bases is often important to clarify whether dependent opacities at supine imaging represent atelectasis or true abnormality. Check for errors and try again. CT features are focal soft-tissue masses, often with irregular or ill-defined margins and calcifications, surrounded by areas of emphysematous change. Radiology. Clinical presentation is insidious and nonspecific with shortness of breath prompting imaging. The literature has primarily focused on the diagnosis, clinical-radiological aspects of COVID-19 pneumonia, and the most common possible differential diagnoses. Immediate subpleural sparing, when present, is considered very specific for NSIP. Radiographic features Plain radiograph. Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. Radiology. Clinical presentation. Lung opacities may gradually resolve over six months without radiological sequelae or with minimal damage . Check for errors and try again. A 47 year old man sustained a head injury after tripping. The French terms "envole de ballons" and "lcher de ballons", which translate to "balloons release", are also used to describe this same appearance. In some situations, there is a rapid progression of the disease which is sometimes termed accelerated silicosis (considered from of rapidly progressive pneumoconiosis). 3. 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. 2003;181 (1): 163-9.

Post-primary infections are far more likely to cavitate than primary infections and are seen in 20-45% of cases. ICIs act through a unique mechanism of action when compared with those of conventional chemotherapeutic agents.

Linear opacities in middle lobe or lingula can be seen, as a result of subsegmental atelectasis or bronchiectasis with mucosal impactions.
