This can cavitate. Other manifestations include pleural effusions and miliary tuberculosis. Other infections can cavitate, including pneumonias due to Staphylococcus , Klebsiella , and Cryptococcus . The outline of the tumour may be spiculated. Look for associated pleural effusion or hilar lymphadenopathy.
Proximal tumours can cause distal consolidation or collapse.
Local rib destruction or multiple bony metastases can also occur so look for these. I would like to thank Dr Anju Sahdev, Dr Brian Holloway, and Dr Robert Dick for contributing some of the films which are illustrated.
