68-Year-Old Woman With Pathologically Diagnosed Small Cell Lung Cancer (IMAGE)
Caption
Per reference-standard diagnosis, TNM stage was IIIA (T3N2M0) and Veterans Administration Lung Cancer Study Group stage was LS. Coronal (A) STIR image and (B) DWI from whole-body MRI. Primary lesion in right hilum (thick arrow) was suspected to be invading right main bronchus, thus assessed as T3. Ipsilateral mediastinal lymph node (thin arrow) was suspected to be metastatic, and N category was thus assessed as N2. (C) Coronal fused PET and STIR image from coregistered FDG PET/MRI show primary lesion in right hilum (thick arrow) and mediastinal lymph node metastasis (thin arrow). (D) Coronal fused image from integrated FDG PET/CT shows primary lesion in right hilum (thick arrow) and mediastinal lymph node metastasis (thin arrow). (E) Coronal image from unenhanced CT shows primary lesion in right hilum (thick arrow) and mediastinal lymph node metastasis (thin arrow). Primary lesion was not suspected to invade right main bronchus invasion. Thus, whole-body MRI, FDG PET/MRI, and FDG PET/CT accurately assessed patient as stage IIIA (T3N2M0) and LS disease. Conventional imaging accurately assessed LS disease, but incorrectly assessed patient as stage IIIA (T2bN2M0).
