Imaging Procedures and Findings

Lesion with low signal in T1WI and high signal in T2WI is seen in anterior of left zygomatic arch and ramus of mandible. Avidly enhancement after GAD is evident (not shown in these pictures ). Angiography reveals hyper vascular lesion in course of ligual and zygomatic artery.

Discussion

masses are secondary to lesions involving anatomic structures that normally traverse spaces of the head and neck, e.g., lymphatics, nerves, and vessels not be localized to one of head and neck spaces.. Examples include the following three categories: (1) lymphatic masses (lymphangioma); (2) neural masses (neurofibroma, schwannoma, perineural spread of tumor); and (3) vascular masses (hemangioma). Differentiation between these subtypes can occasionally be made by virtue of signal intensity characteristics hemangiomas are congenital abnormalities have increased signal intensity on T2WIs and are infiltrative. Hemangiomas may have phleboliths, which may be easily detected on CT.. hemangioma should be considered in a patient with a history of chronic facial swelling and who shows CT or MR evidence of an infiltrative process that traverses several spaces. Some venous hemangiomas may have a similar hypervascular imaging appearance with flow voids .A key feature for the differential diagnosis from paraganglioma is the lack of displacement of the adjacent vessels.
