Correct Answer » B Explanation |
 |
- Thymoma is the most common tumor of the mediastinum overall.
- It arises from the epithelial cells of the thymus and is characteristically located in the anterior mediastinum.
- Therefore, when an MCQ asks for the most common mediastinal tumor overall, the answer is thymoma.
Why the other options are incorrect
- A. Neurogenic tumor
- Neurogenic tumors are the most common tumors of the posterior mediastinum, not the mediastinum overall.
- Examples include schwannoma and neurofibroma.
- C. Pericardial cyst
- A pericardial cyst is a cystic lesion, not a tumor.
- It is an important lesion of the middle mediastinum.
- D. Teratoma
- Teratomas are germ-cell tumors that occur predominantly in the anterior mediastinum.
- They are not the most common mediastinal tumor overall.
