Abstract

Introduction: Epithelioid Hemangioendothelioma (EHE) is a rare vascular neoplasm. Common locations of EHE are the bone, soft tissue, liver, and lung, but the mediastinal location is extremely rare. Few cases of mediastinal EHE, invading the Superior Vena Cava (SVC) have been reported.

Case Presentation: We report a case of a 21-year-old man with EHE invading the SVC, which was incidentally detected on performing chest radiography. A contrast-enhanced chest Computed Tomography (CT) scan demonstrated a well-defined, oval mass located on the right side of the anterior mediastinum. The mass showed homogeneous enhancement with punctate calcifications, and it invaded the SVC at the confluence area of the right and left brachiocephalic veins.

Conclusion: Mediastinal EHE invading the SVC may present as a homogeneously enhancing mass with punctate calcifications. It should be added to the differential diagnosis of tumors of the mediastinum. Accurate preoperative diagnosis of EHE is critical for surgical planning; therefore, knowledge of the radiologic features of EHE is important.

Keywords: Epithelioid hemangioendothelioma, mediastinal tumor, superior vena cava, computed tomography, radiography, punctate calcifications.
