Branchial cleft cyst.
Computed tomography (CT) and magnetic resonance imaging might reveal a unilocular cystic mass in the posterior submandibular space at the level of the mandibular angle. As the mass enlarges, it usually displaces the submandibular gland anteromedially, the sternocleido-mastoid muscle posterolaterally, and the contents of the carotid space posteromedially (figure). The jugulodigastric lymph node is located in the same area as a typical second branchial cleft cyst. As a result, a second branchial cleft cyst can be mistaken for an enlarged suppurative, reactive, or tumor-infiltrated jugulodigastric node.
