The typical radiographic findings of bronchiolitis obliterans organizing pneumonia (BOOP) are known to be patchy air-space consolidation that is often subpleural, and with or without ground-glass opacities. However, there are scant radiologic reports about the micronodular pattern of BOOP. We report here on a case of BOOP that manifested as diffusely scattered ill-defined centrilobular micronodules on HRCT.

Idiopathic bronchiolitis obliterans with organizing pneumonia (BOOP) is a specific clinicopathologic syndrome characterized by a pneumonia-like illness, with excessive proliferation of granulation tissue within bronchioles, alveolar ducts and alveoli. The changes are most numerous in alveolar ducts. The presence of intraluminal tufts of organizing connective tissue in alveolar ducts and more distal airspaces has been termed organizing pneumonia The radiologic manifestations are distinctive with bilateral, diffuse alveolar opacities predominantly in the subpleural and lower lung zone. Patchy migratory pneumonic foci or solely nodular infiltrates are rarely present in BOOP. BOOP is a diagnosis of importance because of its dramatic response to steroids.

A rapid response to corticosteroid treatment and a generally favourable outcome are characteristic features of BOOP (Bronchiolitis obliterans organizing pneumonia). However, with increasing experience of the clinical spectrum of this disease, it is now recognized that some patients are refractory to steroid, which is associated with a poor prognosis. Here, two cases of BOOP initially treated with predinisone and antibiotics without effects, but subsequently responded to secondary cyclosporine treatment, are reported.

Bronchiolitis obliterans organizing pneumonia (BOOP) is a clinicopathologic syndrome of pulmonary inflammatory responses which has become increasingly recognized and has been described in association with a variety of disorders. We present a case of polymyositis associated with BOOP that responded to a corticosteroid therapy. The patient had a nonproductive cough, increasing dyspnea, fatigue, mild proximal limb weakness, and bilateral basal interstitial infiltrates on chest X-ray. This case will add further strength to the association of BOOP with polymyositis. (J Korean Neurol Assoc 19(5):547~549, 2001)

Cryptogenic organizing pneumonia (COP) is an inflammatory lung disease involving the distal bronchioles, respiratory bronchioles, bronchiolar ducts, and alveolae. The etiology is usually unknown; however, there are several known causes and associated systemic diseases. Corticosteroid therapy is the best treatment option and the prognosis of COP is good, with recovery in up to 80% of patients. We described a patient with in-operable hepatocellular carcinoma (HCC) undergoing chemoembolization with doxorubicin in a drug-eluting bead (DEB). COP developed in the patient after chemoembolization but resolved spontaneously in several months.

Diffuse interstitial lung diseases (DILDs) are a heterogeneous group of non-neoplastic, noninfectious disorders resulting from damage to the lung parenchyma, and present with similar clinical features. There has been difficulty in the classification and diagnosis of DILDs because they contain more than 200 diseases. The American Thoracic Society and European Respiratory Society (ATS/ERS) expert meeting have proposed to classify DILDs into 4 categories, (1) known cases, (2) granulomatous diseases, (3) idiopathic interstitial pneumonias (IIPs), and (4) other forms. Among them, IIPs also comprise several different clinicopathological entities; however, it was previously thought to be a single disease, idiopathic pulmonary fibrosis (IPF), and resulted in a lot of confusion. Therefore, the ATS/ERS consensus classification provided a standardized nomenclature and diagnostic criteria of IIPs. IIPs are now classified into seven clinicopathologic entities; IPF, nonspecific interstitial pneumonia (NSIP), cryptogenic organizing pneumonia (COP), acute interstitial pneumonia (AIP), respiratory bronchiolitis-associated interstitial lung disease (RB-ILD), desquamative interstitial pneumonia (DIP), and lymphoid interstitial pneumonia (LIP). Because of these complexities, it is not easy to make the diagnosis of the patients with DILDs. This review will present a brief overview of DILDs and summary of diagnostic approaches with highlights on several specific items. An important thing to emphasize is the diagnosis of DILDs should be multi-disciplinary and the final diagnosis should be rendered only after reviewing all of the clinical, radiological, and pathological data of the patient. The more detailed description and discussion on some common diseases of DILDs will be followed by different authors.
