We describe a rare case of an ectopic submandibular gland associated with atrophy of the ipsilateral floor of the mouth muscles.
Case report and review of the world literature regarding ectopic submandibular glands.
The reported patient had an ectopic submandibular gland associated with atrophy of the ipsilateral anterior digastric and mylohyoid muscles. This implies maldevelopment of these muscles in the floor of the mouth and arrest of the normal migration of the submandibular gland. The condition was diagnosed using magnetic resonance imaging and conventional submandibular gland sialography.
Submandibular gland ectopia in the floor of the mouth is a rare phenomenon. The described case represents the first report of an ectopic submandibular gland associated with atrophy of the ipsilateral floor of the mouth muscles. Radiologists and clinicians should familiarise themselves with this entity and its imaging findings, in order to prevent unnecessary biopsy of this benign condition.
我们描述了一例罕见的异位下颌下腺病例，该病例伴有同侧口底肌肉萎缩。
病例报告及对世界范围内有关异位下颌下腺文献的回顾。
报告的患者有一个异位下颌下腺，伴有同侧二腹肌前腹和下颌舌骨肌萎缩。这意味着口底这些肌肉发育不良以及下颌下腺正常迁移受阻。该病症通过磁共振成像和传统的下颌下腺涎管造影术得以诊断。
口底下颌下腺异位是一种罕见现象。所描述的病例是与同侧口底肌肉萎缩相关的异位下颌下腺的首例报告。放射科医生和临床医生应熟悉这一病症及其影像学表现，以避免对这种良性病症进行不必要的活检。
