Abstract:
Objective To evaluate the role of magnetic resonance angiography ( MRA ) in diagnosing peripheral hemangioma andvascular malformation . Methods 61 cases of hemangioma and vascular malformations in peripheral soft tissue were undergone MRAexamination.Results Of 13 patients with hemangioma,the arteries within hemangioma were increased and gradually fine from proximal to distal in 7 cases and in company with arteriovenous fistulae in 2 cases,there were no arteries within hemangioma in 6 cases.Vascular malformations were found in 48 patients,arteries and veins of vascular malformation were showed in 35 cases,but arteries of vascular malformations were only showed in one case.Arteries of vascular malformation were showed in 5 cases and the arteries were pressed on arterial angioyraphy in 23 cases.On MR venography(MRV),the shallow malformed veina were showed in 25 cases and in company with deep malformed veina in 13 cases,only the shallow and deep veina increased and thickness be showed in 2 cases.Arterioveinous fistulae could be seen in 8 cases on MR aterio-venography.There were no vessel be showed in 12 cases within the losions.Conclusion MRA is of significant value in diagnosis and differential diagnosis of peripheral hemangioma and vascular malformations.
