title: Intramuscular hemangioma of the posterior belly of the digastric muscle failing to highlight on magnetic resonance imaging.
abstract: Intramuscular hemangiomas of the digastric muscle are rare. We present the fifth case reported and the second to be imaged in vivo with magnetic resonance imaging. Accurate preoperative diagnosis of these lesions is difficult, but may be facilitated by a high degree of clinical suspicion and imaging. Magnetic resonance imaging using T2-weighted sequencing has been reported to effectively highlight these lesions. We present a case in which magnetic resonance imaging failed to highlight an intramuscular hemangioma of the posterior belly of the digastric muscle. Possible reasons for this failure are discussed.
