CARACTERíSTICAS RADIOLóGICAS DE LOS HEMANGIOENDOTELIOMAS EPITELIOIDES DE PARTES BLANDAS, HíGADO Y HUESO

objective: to contribute to the awareness of imaging features of epithelioid hemangioendothelioma (ehe) in soft tissues, liver and bone. radiographic images were obtained from patients with histológica! diagnosis of ehe treated in our institution over the past twenty years. we reviewed the computed tomography, mri, and ultrasound findings concerning size, number, behavior with and without intravenous contrast agent, signs of local involvement, and distant metastases. imaging findings were correlated with histológica! results and clinical evolution was analyzed. findings: soft tissue ehe appeared as solid masses without specific features. liver ehe showed a characteristic peripheral location and progressive enhancement. osseous ehe behaved as lytic lesions with soft tissue mass or adjacent edema. two liver ehe and one epithelioid hemangioendothelioma of bone were initially diagnosed as metastasis. conclusion: the epithelioid hemangioendothelioma may pose problems in differential diagnosis; therefore, having awareness of its radiological features enables us to determine proper diagnosis and treatment.
