Dear Friends,
Today I am presenting chest radiographs of a 61-year-old man, asymptomatic.
What would be your diagnosis?
1. Thymoma
2. Teratoma
3. Lipoma
4. Any of the above
You have two days to post your answers. The correct answer will be given during the webinar of next Wednesday at 12:30 noon; you can join the webinar here

Findings: chest radiographs demonstrate an anterior mediastinal mass (A and B, arrows). In an asymptomatic patient, thymoma or teratoma are the best possibilities. A lipoma cannot be excluded because fat cannot be distinguished from soft tissues in the plain film. Therefore, the correct answer should be: 4. Any of the above.
Enhanced coronal and axial CT show an uniform fatty mass in the anterior mediastinum (C and D, arrows)
Final diagnosis: mediastinal lipoma
Congratulations to Katarzyna, who was the first to give the correct answer
Teaching point: remember that fat density cannon be distinguished from soft-tissue density in the plain film
This is the last Diploma case of the season. Will be back in September with new cases
As announced, Dr. Pepe solved this case (amongst others) during the webinar. If you did not have the opportunity to watch the webinar live, you can watch it now on the EBR webpage.
Enjoy your vacation!
