Correct!
1. The thoracic CT shows a non-specific, non-calcified, lobulated left upper lobe nodule corresponding to the chest radiographic finding
The unenhanced thoracic CT shows a lobulated, non-calcified nodule in the left upper lobe, corresponding with the finding present at chest radiography. The CT shows no morphologically specific features, such as fat or calcium, which would suggest a specific diagnosis or allow the lesion to be regarded as likely benign. There is no evidence of a “feeding artery” or “draining vein” that would indicate that he nodule represents an arteriovenous malformation. A few other nodules are visible in the lungs bilaterally, but a “miliary” pattern- diffuse, randomly distributed small, round, discrete nodules (1-3 mm), and typical of a hematogenously disseminated process- is not present.
