title: [Cervical ectopic thymus in an infant].
abstract: Cervical ectopic thymus rarely occur. We reported a case of cervical thymus presenting as a unilateral neck mass in an infant. Ultrasonography showed a low echo-level mass with clear border and abundant blood flow signal in the left neck. Preoperative chest CT revealed normal structures in the superior mediastinum including the thymus. Surgical resection was performed and the histological diagnosis was ectopic cervical thymus.
