External laryngocoele

Case contributed by Dr Praveen Jha

Presentation

Cystic swelling in neck, with recent hoarseness of voice

Patient Data

Age: 30 years
Gender: Male
CT

A cystic lesion is seen adjacent to thyrohyoid membrane on right side, which appears to communicate with larynx, through thyrohyoid membrane. Lesion shows homogenous fluid attenuation, with no post-contrast enhancement.

Case Discussion

Characteristic location and clinical history, as well as CT features, suggest external laryngocele

An important differential consideration is a thyroglossal cyst. However, cyst did not move on deglutition, and typical location favoured a laryngocele.

Information was received about a confirmatory diagnosis from source.
