Thymic Cyst

Thymic cysts are benign lesions along the thymopharyngeal duct, usually in the anterior mediastinum/neck. Congenital (remnant of thymopharyngeal duct) or acquired (inflammatory/neoplastic-associated). Most are asymptomatic incidental mediastinal findings; large cysts may cause cough, chest pain, or compressive symptoms. Thymic malignancy must be excluded; resection for symptomatic or suspicious cysts.

Common Symptoms

Usually asymptomatic incidental mediastinal mass; cough; chest pain; compressive symptoms if large

Causes and Pathogenesis

Congenital thymopharyngeal-duct remnant or acquired inflammatory cyst forms a fluid-filled thymic lesion.

Treatment

Observation for small asymptomatic; surgical resection for symptomatic/suspicious cysts

Preventive Measures

Imaging follow-up; exclude associated thymic tumor.
