Abstract：Objective To study the imaging features of primary bone epithelioid angiosarcoma , to improve the diag-nostic accuracy .Methods Retrospective analysis of 6 cases confirmed by pathology image of primary bone epithelioid angio-sarcoma manifestations.There were 2 male, 4 female, median age 51.7 years, the course of 1-12 months.Results 6 cases of primary bone epithelioid angiosarcoma patients underwent imaging examination , including 1 cases only underwent X-ray ex-amination, X-ray plain film +CT of 1 cases, 2 cases of X-ray plain film+MR, 2 cases of X-ray plain film +CT+MR.The X-ray and CT manifestations:5 cases were with single lesion , 1 cases of multi center for disease;5 cases showed patchy , map like osteolytic bone destruction , a mild swelling, no sclerosis, calcification and periosteal reaction;1 cases were soap bubble obvious expansion growth , hardening visible the basic integrity of the edge , tumor shows irregular calcification .MR features:the tumor was iso-T1, long T2 signal intensity, enhancement of tumor showed inhomogeneous enhancement , with slightly high or low signal in T1WI, high signal on T2WI, 1 cases of tumor can be seen in the small pieces of long T 1, T2 area.Conclu-sion Primary bone epithelioid angiosarcoma is a kind of tumor that endothelial cells were epithelioid morphology as characte -rized and highly malignant vascular tumors , imaging showed lack of characteristic , diagnosis depends on pathological examina-tion.
