Hemangioma of other sites [228.09], Reason for Study: ^Reason: hx right masseter muscle hemangioma sp excision History: hx right masseter muscle hemangioma sp excision MRI NeckThere is relatively well marginated mass located mostly in the right masseter muscle and partly involving right parotid gland. The lesion shows T2 high signal intensity, T1 iso signal intensity with masseter muscle and shows enhancement. In addition, there are multiple small signal void lesions within the lesion especially on T2 weighted images indicate possibility of phleboliths. There are other small lesions within the right parotid gland showing similar MR characteristics.Constellation of these MR finding suggest possibility of venous vascular malformation. PHARYNX/LARYNX: The nasopharynx, oropharynx, and hypopharynx are unremarkable. The larynx is unremarkable. The upper trachea and esophagus are unremarkable. There is no abnormal soft tissue mass or pathological enhancement.GLANDS: The contrast-enhanced appearance of the submandibular, and sublingual glands bilaterally is unremarkable. The thyroid gland is unremarkable. ORAL CAVITY: The oral tongue and the floor of mouth are unremarkable.CERVICAL SOFT TISSUES: Scattered small cervical lymph nodes are identified.OTHER: The visualized intracranial structures are unremarkable.Neck MRA3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The vertebral artery origins are normal. There is normal flow enhancement through the bilateral common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries.
1. Right mainly masseter muscle and partly involving right parotid gland venous vascular malformation as described above. If indicated, percutaneous sclerotherapy can be considered. 2. Normal neck MRA.
