1. What types of lung cancer are there?
2. Which ones are associated with smoking?
3. Identify the tumor in the video. Which lobe is it in?
4. Identify the hilum. How far away is the tumor from the hilum?
5. Review the prior videos in this case or infer from your knowledge of anatomy: How far away was the tumor from the lateral chest wall?
6. How far away was the tumor from the anterior chest wall?
7. Do you think the tumor would have been easily accessed by biopsy.
8. Re-think Parts 1 and 2 of this case. Do you think placement of the needle was appropriate, given the location of the tumor?
9. Why is there hemorrhage around the tumor?
10. Can you identify a specific blood supply for the tumor?
11. Based on the appearance of the tumor and its blood supply and knowing the gross and microscopic anatomy of the lung, can you create a scenario where a biopsy would lead to massive intrabronchial hemorrhage?
12. The autopsy did not identify a specific hole in a specific vessel. Do you think a specific hole would be easy or hard to detect?
13. The autopsy did not identify a specific hole in a specific vessel. How does this affect your analysis?
14. Re-think Part 8 of this case. Why now do you think there is hemorrhage seen on the surface of the right upper lobe?
15. There is a lymph node identified in the video. Find it. What structure is it closest too?
