Angiosarcoma. Diagnosis and clinical course.

The findings at radiography, computed tomography and angiography and the clinical course of 30 cases of angiosarcoma were reviewed. The variety of primary sites results in a multitude of findings but the most common finding was that of a hypervascular soft tissue mass seen on CT and angiography. Additional findings of well demarcated cortical defects in long bones were also frequently noted. The general clinical behavior of these aggressive malignant tumors was also reviewed and it was noted that they had a deceptively benign presentation.
