Overview
Computed tomography is the method of choice for the diagnosis of non-small cell lung cancer. On CT, characteristic findings of large cell carcinoma of the lung, include: ground-glass opacity, rounded mass, large mediastinal node involvement, nodular pleural thickening, and lobar collapse.[1][2]
CT
- Computed tomography is the method of choice for the diagnosis of non-small cell lung cancers
- In some cases, non-small cell lung cancers require further evaluation with MRI
- Common features of CT scan for the diagnosis of non-small cell lung cancers, include:[3]
- Assessment of the main bronchi
- Evaluation of the entire thorax
- Detection of chest wall invasion
- Assessment of hiliar and mediastinal invasion/adenopathy
- Determination of non-small cell lung cancer staging
- Precise determination of size and tumor dimensions
- Detection of liver, bone, adrenal , and brain metastasis
- On CT, common findings of large cell carcinoma of the lung, include:[3]
- Ground glass opacity
- Rounded and well-circumscribed mass
- Large mediastinal nodules/masses
- Rapid growth
- Lymph node involvement
- Frequently subcarinal
- Nodular pleural thickening
- Pleural effusion
- May be loculated
- Usually large
- Narrowing of the lobar and segmental bronchi on the right, due to filling defect.
- Atelectasis
- Early metastasis to brain
