Abnormal dilation of the laryngeal ventricle saccule/appendix. Acquired laryngoceles, such as are caused by coughing, trumpet playing, glassblowing, or tumor obstruction, resulting in elevated laryngeal pressure, and are more common than congenital ones. Secondary laryngoceles may occur when the tumor obstructs the orifice of the laryngeal ventricle and causes laryngocele.

The glottis lies between two horizontal lines, one drawn through the apex of the laryngeal ventricle, the other drawn 1 cm below the medial free edge of the vocal fold when the larynx is at rest. The scaffolding of the false and true vocal folds is formed by the vestibular and vocal ligaments, respectively (see Figures 58.3 and 58.6). Laterally, intervening between the vestibular and vocal ligaments, a horizontal slit opens into an elongated recess, the laryngeal ventricle. From the anterior part of the ventricle, the saccule of the larynx ascends between the vestibular ligament and the inner surface of the thyroid cartilage as high in some people as the upper border of the thyroid cartilage. It occasionally protrudes through the thyrohyoid membrane. Fibrous tissue surrounds the saccule. Dilatation of the saccule results in the formation of a laryngocele. The ventricle and saccule can harbour occult cancers and need to be actively inspected during diagnostic endoscopy.

A 45-year-old trumpet player presented with a lump in the right side of the neck, which appeared to grow in size when the man was playing the trumpet and become less prominent when he was relaxed. CT showed clearly defined, round, radio lucency in the soft tissue of the right side of the neck lateral to the larynx. A normal barium swallow report was available in the system for suspected swallowing difficulty performed at a different hospital. What is the likely diagnosis?

Differential diagnosis of congenital neck masses include variety of diseases. They are classified in three categories: inflammatory, neoplastic and congenital. Congenital neck masses include branchial cleft cysts, thyroglossal duct cysts, laryngocele, ranula, dermoid cyst, and thymic cyst [1]; teratomas and LMs are also included.
