    Abstract:
    A 60-year-old woman was admitted to our department for evaluation of a hepatic mass. The mass was diagnosed as a hemangioma of the liver by abdominal angiography because of typical cotton wool appearance and stretched arterial vessels and no peripheral staining. However, one month later, the mass was surgically removed because of extravasation. Histological findings of a specimen of the mass revealed that it entirely contained abundant necrotic tissue, and a small residual part after transcatheter arterial embolization was consistent with hemangioma. However, she complained of hemoptysis and thigh pain after several weeks. Computed tomography revealed multiple lung masses and a mass of right musculus gluteus medius. Reexamined histological findings of the liver tumor showed hemangiosarcoma. We should pay attention to the fact that it is sometimes difficult to differentiate cavernous hemangioma from angiosarcoma by angiography.
