Abstract:
Objective To study MRI differential diagnosis of peripheral hemangioma and vascular malformations.Methods MRIfindings of peripheral hemangiomas and vascular malformations proved by operation in 61 cases were retrospectively analyzed in comparison with pathological results.Results In 29 cases of peripheral hemangiomas,20 cases showed equal signal intensity (equal to muscle) and 9 cases showed heterogeneous signal intensity on T1-weighted images; 24 cases showed increased signal intensity (approach fat signal) and 5 cases showed markedly increased signal intensity (increase fat signal) on T2-weighted images,25 cases had septa as low signal network on T2-weighted images,4 cases showed enhancement separated mass enhancement after intravenous contrast injection.In 32 cases peripheral vascular malformations,16 cases showed equal signal intensity and 16 cases showed heterogeneous signal intensity on T1-weighted images.3 cases showed high signal intensity and 29 cases showed markedly increased signal intensity on T2-weighted images,15 cases showed inhomogeneous enhancement after intravenous contrast injection.Conclusion MRI plays an important role in differential diagnosis of peripheral hemangiomas and vascular malformations.
