What are the angiographic features of metastatic fibrous histiocytoma?
What are the angiographic features of metastatic fibrous histiocytoma?
Metastatic fibrous histiocytomas exhibit distinct angiographic features depending on their location, such as avascularity in the brain and hypovascularity with corkscrew vessels in the kidneys.
Site-specific angiographic patterns seen in one metastatic fibrous histiocytoma case; leaves open diagnostic value in larger cohorts.
The angiographic findings in 2 cases of metastatic fibrous histiocytoma are discussed. A lesion in the brain was completely avascular and displaced the surrounding vessels, whereas the renal lesions were hypovascular, usually well demarcated, sometimes exhibited beak formation, and demonstrated fine, corkscrew-like tumor vessels with delayed emptying but no tumor blush or early draining veins.
