Abstract:
Objective To study the manifestations and diagnostic value of MRI for cavernous hemangioma in maxillofacial region.Methods Thirty-one cases of cavernous hemangioma in maxillofacial region proved pathologically were retrospectively analyzed.Results The lesions localized in parotideomasseteric region in 13 cases,in buccal and zygomalicotemporal region in 12 cases,in orbital area in 3 cases and labium in 3 cases.The lesions appeared as ellipse or round-like in 3 cases,fusiform in 2 cases,mass or flat irregular shape in 26 cases.On MRI,20 cases showed long T1 signal intensity,4 cases were slight long T1 and 7 cases were equal T1;on T2WI,27 cases showed high signal intensity and 4 were slight signal intensity.Conclusion The diagnosis of cavernous hemangioma in maxillofacial region can be verified and the shape,the extent of lesion can also be showed by MRI.It provides a reliable basis for clinical diagnosis and operative plan.
