갑상선 초음파상 결절로 오인하기 쉬운 Killian-Jamieson 게실: 증례 보고

Abstract

Pharyngoesophageal or Killian-Jamieson diverticulum is due to herniation of the mucosa and submucosa of the pharynx through a potentially weak area of the pharyngeal wall. It originates on the anterolateral wall just below the cricopharyngeous. It can be detected incidentally during thyroid ultrasonography (US). We present here a case report of pharyngoesophageal (Killian-Jamieson) diverticulum mimicking a thyroid nodule on US. We discuss the image findings that might be useful for the differential diagnose and to prevent invasive procedures such as needle aspiration biopsy.
