  • Information About Lung Nodules
    Information about lung nodules Introduction/procedure You have been informed that you have a nodule (or nodules) in your lung. This is a very common finding and is usually nothing to worry about. Lung nodules are often very small (too small to investigate further) and cause no symptoms. They are often found incidentally whilst having a chest x-ray or CT scan for another condition and do not affect the function of the lungs or interfere with breathing. Once discovered, it’s important to observe the appearance of the nodule(s) over time. This is done by repeating an x-ray or CT scan of your chest at certain intervals. Some nodules can be seen on chest x-ray whilst others require a CT scan to be seen clearly. The interval between the scans or x-rays is usually 3 or 6 months and is determined by your age, whether you smoke and the original size of the nodule(s). It is not the same for everyone, but we follow nationally agreed guidelines. After each scan, the images will be reviewed by the specialist chest team and the nodules measured. You will be informed of the result of the review by telephone 2-3 weeks after the scan. Most lung nodules stay exactly the same size, get smaller or even disappear over time. If a nodule has not increased in size over a series of scans or x-rays, you will be informed that no more follow up is required. Rarely a lung nodule may increase in size. If so, it’s important to determine the nature of the nodule and further investigation will be necessary.

  • Radiation-Induced Organizing Pneumonia: a Characteristic Disease That Requires Symptom-Oriented Management
    International Journal of Molecular Sciences Review Radiation-Induced Organizing Pneumonia: A Characteristic Disease that Requires Symptom-Oriented Management Keisuke Otani *,†, Yuji Seo † and Kazuhiko Ogawa † Department of Radiation Oncology, Graduate School of Medicine, Osaka University, Suita 565-0871, Japan; [email protected] (Y.S.); [email protected] (K.O.) * Correspondence: [email protected]; Tel.: +81-6-6879-3482 † These authors contributed equally to this work. Academic Editor: Susanna Esposito Received: 30 November 2016; Accepted: 24 January 2017; Published: 27 January 2017 Abstract: Radiation-induced organizing pneumonia (RIOP) is an inflammatory lung disease that is occasionally observed after irradiation to the breast. It is a type of secondary organizing pneumonia that is characterized by infiltrates outside the irradiated volume that are sometimes migratory. Corticosteroids work acutely, but relapse of pneumonia is often experienced. Management of RIOP should simply be symptom-oriented, and the use of corticosteroids should be limited to severe symptoms from the perspective not only of cost-effectiveness but also of cancer treatment. Once steroid therapy is started, it takes a long time to stop it due to frequent relapses. We review RIOP from the perspective of its diagnosis, epidemiology, molecular pathogenesis, and patient management. Keywords: organizing pneumonia; bronchiolitis obliterans organizing pneumonia; breast cancer; corticosteroid treatment; radiation-induced organizing pneumonia 1. Introduction Pneumonia is one of the most common causes of death around the world, but various pathogeneses may be responsible. It is divided into alveolar and interstitial pneumonia, and interstitial pneumonia needs further classification [1]. Organizing pneumonia (OP) is a type of interstitial pneumonia and consists of cryptogenic organizing pneumonia (COP) and secondary organizing pneumonia (SOP) [2].

  • Aspergillosis and the Lungs Fungal Disease Series
    American Thoracic Society PUBLIC HEALTH | INFORMATION SERIES Aspergillosis And The Lungs Fungal Disease Series Aspergillosis (As-per-gill-osis) is an infection caused by a fungus called Aspergillus. Aspergillus lives in soil, plants and rotting material. It can also be found in the dust in your home, carpeting, heating and air conditioning ducts, certain foods including dried fish and in marijuana. Aspergillus infection is occurring more often and is now the leading cause of death due to invasive fungal infections in the United States.

Materials and Methods : HRCT scans of 46 patients (31 with malignant and 15 with benign lesion) with a solitary pulmonary nodule seen on chest radiograph were distributed in random order and analyzed retrospectively. Two blinded observers jointly analyzed the marginal and internal characteristics of nodules as seen on HRCT, and decisions on the findings were reached by consensus. Stepwise discriminant analysis for characteristic findings ofBAC was performed. Results : The most frequent CT findings ofBAC (n= 15) were internal bubble lu­ cency (1 4/15, 93 %)(p=O .-OOl), area of ground-glass opacity (12/1 5, 80 % ; average 58 % of tumor volume)(p=O.OOOl), pleural tag(12/15, 80 % ; p=0.097), and lobulated and spiculated margin(8/1 5, 53 % ; p=0.459). Findings of ground-glass opacity (p=O.OOOl) and bubble lucency (p=0.0187) appeared to be discriminant in the diagnosis of BAC. Conclusion : Peripheral pulmonary nodules containing an area of ground-glass opacity associated with internal bubble-lucency are characteristic ofBAC.

Appearance: The reversed halo sign (also known as the atoll sign, reverse halo sign, and the fairy ring sign) is defined by central ground-glass opacity with a surrounding halo or crescent of consolidation (Fig. 1).1 This should not be confused with the halo sign which refers to central consolidation with a surrounding halo or rim of ground-glass opacity.2 Furthermore, the reversed halo sign should be differentiated from cavitation (development of focal regions of internal gas) or pseudocavitation (likely internal bronchiolectasis described in subtypes of lung adenocarcinoma). Explanation: Pathology of the reversed halo sign in cryptogenic organizing pneumonia (COP) demonstrates alveolar septal inflammation corresponding to central ground-glass opacity and granulomatous tissue in peripheral airspaces (organizing pneumonia) in areas of peripheral consolidation.3 In patients with South American blastomycosis
