Conventional and magnetic resonance angiographic evaluation of cirsoid aneurysm

Cirsoid aneurysms are considered to be notoriously difficult lesions. A proper diagnostic evaluation is essential for the successful management of these lesions. The authors present here both conventional and magnetic resonance angiographic appearance of six cases of cirsoid aneurysms. Four of these had congenital and two had post traumatic cirsoid aneurysms. Only two out of the six patients were evaluated by magnetic resonance angiography, while all the six patients underwent conventional angiography. Though magnetic resonance angiography described the feeders of the malformation well, it could not define the draining veins satisfactorily. On the contrary, conventional angiography described both feeding arteries and the venous drainage.
