This was performed to observe various radiological presentations of lung cancer at the initial evaluation and to elicit correlation to histopathological diagnosis in all patients to a tertiary chest care hospital. AIM: To study various radiological presentations among lung cancer patients Method: we included all the patients with lung cancer reviewed during a 12mth period between March 2012 to November 2014 who had a definite tissue diagnosis and whose staging based on CT thorax were available. RESULTS: 65 patients were evaluated. Right sided lesions predominated with 60% and on left side being 40%. On either side put together, upper lobe 46.15% & middle lobe 36.9% and lower lobe 16.9%.Based on location of tumor 26% of the lesions are peripherally located, 24.5% are central localization, 13.8% are located intermedially. Radiological pattern of presentation: 67% of the cases presented as mass lesions, 9% as obstructive pneumonitis and 23% as combined mass with collapse and 23.07% as pleural effusion. Histological pattern of presentation: squamous cell carcinoma is most common type with 49.23%, adeno 33%, small cell 15%, others 1.5% Most of the cases presented to the hospital in stage IV with 56.36% and stage IIIA 16.36% and stage IIIB as 18.18%. CONCLUSION: we observed most of the lung cancers presented as mass lesion with peripherally located tumor and the most common histological type is squamous cell carcinoma, presented at advanced stages.

BACKGROUNDScimitar syndrome is characterised by hypoplasia and anomalous pulmonary venous drainage of right lung. Because of its rarity, we present a case of a 21-year-old male who came with respiratory tract symptoms and pulmonary arterial hypertension and was diagnosed as Scimitar syndrome with unilobar right lung based on imaging methods and FOB findings.
