Colonic Metastasis with Anemia Leading to a Diagnosis of Primary Lung Adenocarcinoma

Figure 3

CT scan of the chest demonstrating lung lesions. (a) Transverse view CT scan without IV contrast shows a 3.6 by 4.9 by 2.9 cm mass in left upper lobe (arrow). Interaction with the oblique fissure is noted. (b) Coronal view showing left upper lobe lesion (arrow) without any mediastinal or hilar lymphadenopathy. (c) A pulmonary nodule is visualized in the right lung (contralateral). This mass was not biopsied and was assumed to be secondary to the primary adenocarcinoma in the left lung.
