Large right cervicofacial soft tissue mass showing the following characteristics:
- composed of numerous serpiginous vascular structures
- displaying a low signal on T1, high signal on T2 and T2 fat sat with no restricted diffusion
- vivid enhancement on the postcontrast sequences (dynamic sequences not performed)
- centered on the parotid space with extension to the following spaces:
- parapharyngeal space compressing and displacing the oropharynx to the left
- carotid space encasing the internal carotid artery up to its intracavernous segment as well as the ipsilateral internal jugular vein
- submandibular space with involvement of the submandibular gland, and the right premandibular space, displacing the masseter muscle
- infratemporal and pterygopalatine fossae
- involvement of the medial pterygoid muscle
- posterior cervical space displacing the SCM muscle
- intraosseous extension of the temporal bone (mastoid and petrous parts)
- pre-and retroauricular soft tissues
Case Discussion
MRI features of a large cervicofacial mass composed of numerous enhancing vascular structures with multidirectional extension highly suggestive of slow-flow vascular malformation.
