Imaging Diagnosis of Epithelioid Hemangioendothelioma in Thoracic Vertebrae and Liver.

Abstract

Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor of uncertain biologic behavior. Most cases come out as a single lesion of the soft tissue but also may appear in the lung, liver, and other locations. EHE in bone, especially in thoracic vertebrae, is an extremely rare occurrence and signifies a challenge for the imaging diagnosis. This paper presents a rare case of EHE occurring in thoracic vertebrae and liver revealed by fluoride-18-fluorodeoxyglucose-positron emission tomography and magnetic resonance imaging to provide a better understanding of its clinical application and further insight into diagnosing a rare thoracic tumor.
