title: Aberrant cervical thymus in an infant: an unusual cause of stridor.
abstract: We report an 8-month-old infant presenting with stridor caused by a nonpalpable neck mass discovered at imaging and surgery. The diagnosis of aberrant thymic tissue was confirmed at histopathology. The authors reviewed the literature and discuss the embryology, imaging findings and differential diagnosis of this rare disorder.
