On conventional radiography, characteristic findings of large cell carcinoma of the lung, include: large rounded peripheral mass, bulky hilum (representing the tumor and local nodal involvement), and lobar collapse.^[1]

• Conventional chest radiograph may be helpful in the diagnosis of large cell carcinoma of the lung
• The majority of non-small cell lung cancers require further evaluation with CT scan and MRI
• Common features of conventional radiography to perform the diagnosis of non-small cell lung cancers, include:^[2]

• Primary detection and characterization of parenchymal tumor
• Assessment of main bronchi and tracheal involvement
• Detection of chest wall invasion
• Assessment of hiliar and mediastinal invasion/adenopathy
• Detection of obstructive atelectasias and signs of pneumonitis
• Detection of pleural effusion

• On conventional radiography, characteristic findings large cell lung cancer, include:^[2]

• Rounded large peripheral mass
• Bulky hilum (representing the tumor and local nodal involvement)
• Lobar collapse
• Pleural effusion

• On conventional radiography, signs of large cell carcinoma of the lung, include:^[2]

• Golden “S” sign: created by a central mass obstructing the upper lobe bronchus and should raise suspicion of a primary lung cancer. Usually seen with right upper lobe collapse.
• Coin lesion: round or oval, well-circumscribed lesion
• Luftsichel sign: curvilinear opacity represents compensatory hyperinflation of the lobe
• Bronchial cut off sign: abrupt truncation of a bronchus from obstruction
