Killian-Jamieson diverticulum: real-time sonographic findings

Area of Science:

• Radiology
• Gastroenterology
• Otolaryngology

Background:

• Killian-Jamieson diverticulum (KJD) is a rare pharyngoesophageal outpouching.
• Its cervical location often leads to misdiagnosis as a thyroid nodule on ultrasound.
• Accurate differentiation is crucial for appropriate patient management.

Observation:

• A case of incidental Killian-Jamieson diverticulum (KJD) discovered during neck ultrasound.
• The diverticulum's characteristic changes in shape during dynamic ultrasound scanning were noted.
• These dynamic findings were key to differentiating KJD from a thyroid lesion.

Findings:

• Dynamic ultrasound assessment successfully identified the Killian-Jamieson diverticulum.
• The characteristic change in shape during swallowing or neck movement confirmed the diagnosis.
• This non-invasive method prevented misinterpretation as a thyroid nodule.

Implications:

• Neck ultrasound can detect Killian-Jamieson diverticulum (KJD).
• Dynamic scanning is essential for differentiating KJD from thyroid nodules.
• Accurate ultrasound diagnosis can prevent unnecessary invasive procedures like fine needle aspiration.
