[Angiographic findings in chondrosarcomas]

In chondrosarcomas, angiography may be helpful in confirming malignancy, delineating the anatomic extent and detecting recurrence. The angiographic findings in three chondrosarcomas are demonstrated including a vertebral one, abrupt narrowing of tumor vessels, neovascularlity and accumulation of contrast medium during the capillary phase. Changing calibre of arteries and neovascularity are better seen on selective angiograms and after subtraction technique.
