Rare presentation of Ewing sarcoma metastasis to the sella and suprasellar cistern.
We present an exceedingly rare case of a Ewing sarcoma metastasis manifesting as a sellar mass mimicking a pituitary adenoma. The differential diagnosis of the young adult with a sellar mass is presented and correlated with a review of available literature, demonstrating this case's unique potential for clinical teaching. More specifically, this case illustrates that in a patient with a clinical history of Ewing sarcoma, a metastasis may involve the sella and suprasellar cistern without apparent osseous involvement.
