(A) Abdominal CT enhancement scan showed a mixed density image of about 22 * 28 mm in the IVC area with calcification and fatty density images [The lesion was indicated by the arrow in (A-C)]. (B) The mass originated from the wall of the IVC. (C) The mass had been removed, and the inferior vena cava was open and remains to be sutured. (D) The tumor was 2.5 cm in size, gray-red in color, solid and hard in texture. (E) Histopathological examination showed that mature bone fragmentation, hematopoietic tissue of bone marrow, and some free wall-like tissues were mainly seen under the microscope. (F) Immunohistochemical test showed positive ERG.

IVC area and below the right renal vein, contained calcification and fatty density (Figure 1A). It was considered to be a retroperitoneal neoplasm compress the inferior vena cava. After conversion to open surgery (Figure 1B), we resected the mass and partial IVC wall adhered to the mass (Figure 1C), then repair the IVC wall with an extended polytetrafluoroethylene graft. On naked eye examination, the tumor was 2.5 cm in size, gray-red in color, solid and hard in texture (Figure 1D). Cytoplasmic vacuoles (immunophenotype suggests vascular endothelium) with interstitial hyaline degeneration which consistent with epithelioid hemangioendothelioma was also found in it (Figures 1E,F).
