title: MR imaging of a lymphangioma involving the masseter muscle.
abstract: Lymphangiomas and cystic hygromas are tumors of lymphatic origin that are relatively common in the head and neck area. However, based on our literature review of this subject, the masseter muscle has never been implicated as a primary tumor site. It is our purpose to report such a case and to emphasize the value of magnetic resonance imaging for diagnosing a mass located in the masseteric region.
