title: Intramuscular cavernous hemangioma arising from masseter muscle: a diagnostic dilemma (2006: 12b).
abstract: We report here a case of intramuscular cavernous hemangioma of the right masseter muscle in a 41-year-old woman-misdiagnosed preoperatively as parotid tumor-along with its imaging and pathologic findings. Preoperative diagnosis of intramuscular cavernous hemangiomas of the masseter muscle is problematic, in that they may be confused with parotid tumor or other muscular lesions. In a patient with soft-tissue mass suspected of representing a hemangioma, MR imaging may provide more specific information regarding the characteristics, the origin, and the extent of the lesion than other imaging modalities.
