A 42-year-old young adult male presented with history of fever and cough with sputum production for duration of 10 days. He also had history of dyspnea for 4 days and 2 episodes of hemoptysis. Examination of the respiratory system revealed decreased breath sounds and dull note on percussion over LEFT infrascapular area. No other positive signs were noted.
Plain film features are often non specific. They are most frequently seen as round or oval opacities with sharp and often notched margins 2. Associated airway compression with pulmonary atelectasis may be also seen in some cases. IN THIS CASES THERE IS HYPER LUCENCY OF LEFT HEMITHORAX WHICH IS ASSOCIATED TO AIR TRAPPING. CECT:Central lesions are usually seen as a single hilar or perihilar mass which is usually well-defined, round or ovoid. can be of any size but typically range ~ 2-5 cm. there is often marked homogeneous contrast enhancement due to high vascularity. calcifcation (usually eccentric) can occur but is not a common feature.
a differential diagnosis of bronchial carcinoid is to be kept in mind apart from pulmonary tuberculosis in a young patient presenting with recurrent episodes of pneumonitis and hemoptysis

Discussion (Related Text)
Bronchial carcinoid tumours are carcinoid tumours primarily occurring in relation to a bronchus. They were previously incorrectly termed as bronchial adenomas 10. Bronchial carcinoids are uncommon, slow growing, low-grade malignant neoplasms comprising 1-2% of all primary lung cancers. They are thought to arise from neuroendocrine/Kulchitsky's cells of bronchial epithelium. They usually occur in association with a segmental or larger bronchus. Carcinoid tumours of the lung fall into a subgroup of neuroendocrine tumours of the lung. They fall under lower end of grade and are not as high grade as small cell carcinoma of the lung or large cell neuroendocrine carcinoma of the lung. Typically affects patients from 3rd to 7th decades with the mean age around 45 years 6,9. Clinic Carcinoid tumours can also be divided into two groups dependent on location as follows bronchial carcinoid tumours - central lesions peripheral pulmonary carcinoid tumours - peripheral lesions
