    i beg to differ

    i think the answer is lung abscess.

    clubbing takes place only in long standing hypoxia...except lung abscess(which is acute) all the others r chronic.
    in case of bronchogenic carcinoma the clubbing is part of the paraneoplastic syndrome

    OHCM 54. Thoracic causes are:

    * bronchial carcinoma
    * chronic lung suppuration (empyema, abscess, bronchiectasis,cystic fibrosis )
    * fibrosing alveolitis
    * mesothelioma

    Common causes of finger clubbing can be divided up according to the system with primary pathology:

    cardiovascular causes:
    cyanotic congenital heart disease
    infective endocarditis

    respiratory causes:
    lung carcinoma - usually squamous cell carcinoma
    pulmonary fibrosis, especially fibrosing alveolitis
    cystic fibrosis
    chronic pulmonary suppuration:
    lung abscessThe clubbing seen with bronchogenic carcinoma is often part of a hypertrophic osteoarthropathy.

    Uncommon causes of finger clubbing can be divided up according to the system with primary pathology:

    cardiovascular causes:
    atrial myxoma

    respiratory causes:
    tuberculosis - typically within 6 weeks of onset
    pleural mesothelioma

    gastrointestinal causes:
    liver cirrhosis
    ulcerative colitis
    Crohn's disease
    coeliac disease

    thyroid acropachy in thyrotoxicosis

    ut there is no information about bronchitis

    Clinical features:

    progressive dyspnoea
    clubbing -> conferms bronchitis
    bilateral end-inspiratory crackles

    CXR - diffuse bilateral shadowing, honeycomb lung. There may be pleural plaques which are an indicator of previous exposure to asbestos. However, pleural plaques do not indicate lung disease or any increased risk over similarly exposed subjects of developing a tumour.
    Lung function tests - severe restrictive ventilatory defect; reduced gas transfer.
    Lung fibrosis not detectable on CXR may be revealed on CT scan.
