Abstract

Abnormalities of the anterior belly of the digastric muscle are rare but have received increased attention by radiologists in recent years in an attempt to avoid confusion with submental cysts or enlarged submental lymph nodes on CT or MR images. We present a case of bilateral accessory digastric muscles which fuse (partially) with the midline raphe of the mylohyoid muscle. Fibres from the right accessory anterior digastric muscle proceeded to decussate and join the mylohyoid muscle and the contralateral insertion of the digastric muscle. Embryological development and possible clinical consequences are discussed.
