Bronchiolitis (plural: bronchiolitides) is a broad term that refers to any form of inflammation of the bronchioles. It is often used in situations where there inflammation primarily occurs in airways smaller than 2 mm 6. It can carry variable clinical, functional and morphological expression constrictive bronchiolitis refers to bronchiolar narrowing from adventitial and submucosal fibrosis. Bronchiolitis is not usually detected at chest radiography. However, bronchiolitis may manifest with nonspecific findings such as ill-defined small or hazy clustered nodules or areas of air trapping characterized by hyperlucency and/or oligemia Some types of bronchiolitis affect specific ethnic groups or are associated with a characteristic clinical history. For example, diffuse panbronchiolitis typically affects Japanese subjects. Constrictive bronchiolitis should be considered in lung transplant recipients with ongoing rejection. Given the high frequency of bronchiolitis, radiologists should develop a systematic approach to both cellular and constrictive bronchiolitis. Recognition of specific clinical or imaging characteristics. Bronchiolitis may be classified into inflammatory and fibrotic subtypes. Direct signs of bronchiolitis include centrilobular nodules and tree-in-bud pattern. Indirect signs include mosaic attenuation and air trapping. High-resolution CT findings correlate with the histology of different forms of bronchiolitis. The CT features presented in this article represent the typical features associated with each entity. Although classic examples of each entity exist, there can be substantial overlap. Usually respiratory bronchiolitis has no imaging findings, although occasionally minor patchy ground glass opacities and ill-defined centrilobular nodules may be seen, which tend to be more pronounced in the upper zones 2. History and etymology. It is thought to have been first described by D E Niewoehner et al. in 1974 3,4. See als
While the term bronchiolitis in itself implies inflammation of the bronchioles by definition, some authors group the term inflammatory bronchiolitis as a specific group in terms of imaging as distinct from the more fibrotic - constrictive type 1. Conditions that are described under this include infective bronchiolitis - infectious bronchiolitis Radiologists consciously or unconsciously encounter bronchiolitis on images frequently. The purpose of this article is to simplify the concept of bronchiolitis to facilitate the formulation of a succinct and accurate differential diagnosis and suggest potential causes for the imaging findings. Direc Patients with acute tracheobronchitis usually have normal radiologic findings. Occasionally, tracheal or bronchial wall thickening may be seen. Bronchiolitis is characterized at high-resolution CT by the presence of centrilobular nodules and branching linear or nodular areas of increased attenuation having a tree-in-bud appearance ( Fig 12). The centrilobular nodules have a patchy distribution in the lung It was described in earlier years as Bronchiolitis-obliterans-organizing pneumonia (BOOP). Patients with COP typically present with a several-month history of nonproductive cough. Many cases are idiopathic, but OP may also be seen in patients with pulmonary infection, drug reactions, collagen vascular disease, Wegener's granulomatosis and after toxic-fume inhalation Direct signs of bronchiolitis include centrilobular nodules and tree-in-bud pattern. Indirect signs include mosaic attenuation and air trapping. Although classic examples of each entity exist, there can be substantial overlap in the appearances, and distinguishing among these entities is not always possible. When high-resolution CT features overlap, clinical details will usually help to narrow the differential diagnosis
. OB should not be confused with bronchiolitis obliterans organizing pneumonia (BOOP) PURPOSE: To evaluate the thin-section computed tomographic (CT) findings of follicular bronchiolitis and compare them with the histologic findings. MATERIALS AND METHODS: Thin-section CT scans obtained in 12 patients (age range, 24-77 years; mean age, 47 years) with follicular bronchiolitis proved at open lung biopsy were reviewed by two observers
Bronchiolitis is characterized by centrilobular nodules and branching linear or nodular areas of increased attenuation (tree-in-bud pattern). Obstructing bronchopulmonary aspergillosis mimics allergic bronchopulmonary aspergillosis at CT and manifests as bilateral bronchial and bronchiolar dilatation, large mucoid impactions, and diffuse lower lobe consolidation caused by postobstructive atelectasis. Characteristic CT findings in angioinvasive aspergillosis consist of nodules surrounded by. Bronchitis (plural bronchitides) refers to inflammation of large airways (i.e. bronchi). Terminology. It is considered a generic term referring to inflammation of the bronchial wall, representing the common final response of the airways to various irritants 3. Types. This may be acute or chronic and can be precipitated by a variety of conditions . Amyloidosis: Amyloidosis is characterized by extracellular deposition of various proteins in β-pleated sheets and may be localized (10-20%) or.
Bronchiolitis obliterans (BO) is a disease of small airways that results in progressive dyspnea and airflow limitation. It is a common sequela of bone marrow, lung, and heart-lung transplantation, but can also occur as a complication of certain pulmonary infections, adverse drug reaction, toxic inhalation, and autoimmune disorders Bronchiolitis mit air trapping bei allergischer Alveolitis (Hypersensitivitätspneumonie).

At histopathologic analysis, interstitial lung diseases associated with collagen vascular diseases are diverse and include nonspecific interstitial pneumonia, usual interstitial pneumonia, bronchiolitis obliterans organizing pneumonia (BOOP), apical fibrosis, diffuse alveolar damage, and lymphocytic interstitial pneumonia. Although proportions of interstitial pneumonias vary, nonspecific interstitial pneumonia accounts for a large proportion, especially in progressive systemic sclerosis.
Bronchiolitis in hypersensitivity pneumonia appears with poorly defined centrilobular nodules, associated with ground-glass opacity and air trapping. The most common high resolution CT (HRCT) findings of bronchiolitis are centrilobular nodules and branching linear structures in the secondary pulmonary lobules or areas of air trapping. These findings can be helpful in suggesting the presence of. FIG. 3.20 • Respiratory bronchiolitis-associated interstitial lung disease (RB-ILD). This patient had a long history of cigarette smoking, chronic cough, and shortness of breath. CT scan shows bilateral reticular and ground-glass opacities in a predominantly upper lung distribution. AIP is a rapidly progressive form of interstitial pneumonia characterized histologically by hyaline membranes. Temporary bronchiolitis with air trapping is seen in: (post) infection; Inhalation of toxin; Rheumatoid arthritis, Sjogren; Post transplant; Drug reaction (penicillamine) Mosaic pattern in a patient with hypersensitivity pneumonitis.

Histologic bronchiolar abnormalities seen in asthma include bronchiolar wall thickening, mucus stasis in bronchioles, and constrictive bronchiolitis (Figs. 4A and 4B). Between clinical episodes, the bronchioles may be (nearly) normal when viewed in tissue collected for other reasons from asthmatic patients (Colby TV, personal observation). The high-resolution CT manifestations include areas of.

Focal bronchiolitis was the most frequently encountered pattern (25%, 100 of 406), but a definitive diagnosis for the cause of the disease was rarely identified, because the clinicians caring for the patient chose to not perform further evaluations to diagnose the cause . Our study suggests that this type of disease is often asymptomatic. We believe that in most cases a pattern of focal TIB. . Imaging plays a crucial role in the detection and management of patients with pneumonia. This review article discusses the different imaging methods used in the diagnosis and management of suspected pulmonary infections Constrictive bronchiolitis should be considered in lung transplant recipients with ongoing rejection.

Infections of the lower respiratory tract can remain localized to the airways (resulting in tracheitis, bronchitis, and bronchiolitis) or can reach the lung parenchyma (resulting in pneumonia). Even though a CXR is generally sufficient to establish the diagnosis of a pneumonic process, an HRCT becomes necessary in many cases, particularly if atypical processes or bronchiolar involvement occur Bronchiolitis is characterized by centrilobular nodules and branching linear or nodular areas of increased attenuation (tree-in-bud pattern).

Bronchiectasis is a chronic respiratory disease characterised by a syndrome of productive cough and recurrent respiratory infections due to permanent dilatation of the bronchi. Bronchiectasis represents the final common pathway of different disorders, some of which may require specific treatment. Therefore, promptly identifying the aetiology of bronchiectasis is recommended by the European. Bronchiolitis, a generic term applied to various inflammatory diseases affecting the bronchioles, is the most common form of disease affecting small airways (1, 2).
