Cervical thymic cyst mimicking laryngocele

Area of Science:

• Medical Science
• Surgical Pathology
• Congenital Abnormalities

Background:

• Cervical thymic cysts constitute approximately 0.3% of all congenital cervical cysts.
• Typically asymptomatic, thymic cysts can rarely present with dysphagia or tracheal obstruction.
• A soft, mobile, painless mass that enlarges with the Valsalva maneuver is characteristic of a laryngocele.

Purpose of the Study:

• To report a unique case of a cervical thymic cyst presenting with symptoms mimicking a laryngocele.
• To highlight the importance of considering thymic cysts in the differential diagnosis of neck masses with laryngocele-like features.
• To contribute to the literature by documenting an unprecedented clinical presentation of a thymic cyst.

Main Methods:

• Case report presentation.
• Review of clinical presentation, diagnostic findings, and management.
• Literature search for similar reported cases.

Main Results:

• A patient presented with a neck mass exhibiting characteristics typically associated with a laryngocele.
• Diagnostic evaluation revealed the mass to be a thymic cyst, a presentation not previously reported.
• The cyst mimicked laryngocele presentation, including enlargement with the Valsalva maneuver.

Conclusions:

• Cervical thymic cysts can present atypically, mimicking other conditions such as laryngocele.
• This case underscores the need for comprehensive diagnostic evaluation for congenital neck masses.
• Further research may be warranted to understand the varied presentations of thymic cysts.
