Answer

A CT scan of the primary lesion and a CT scan of the chest (high resolution) should be obtained. CT of the primary lesion helps delineate the location and extent of the tumor and is critical for surgical planning.

CT of the chest is more sensitive than plain film radiography is for assessing pulmonary metastases. Ideally, the chest CT scan of the chest should be obtained before a biopsy is performed so as to avoid the ambiguity that can arise from postanesthesia atelectasis.
