CABANE T, PATRICIO et al. Laryngocele as a differential diagnosis of a thyroid cyst. Rev Chil Cir [online]. 2011, vol.63, n.4, pp. 415-417. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262011000400014.

A cervical mass is a usual complaint within the clinical practice. Among possible causes, thyroid cysts and nodules are frequent findings. However, there are differential diagnoses that arise from neighboring structures, which can be difficult to assess. We report an 18 years old male presenting with a cervical mass, clinically and ecographically suggestive of a right thyroid cyst. Fine needle aspiration was negative for neoplastic cells. Within surgery a paratracheal lesion was identified and resected. The histological findings were compatible with a laryngocele. A laryngocele is an abnormal dilatation of the laryngeal sacule that can simulate a thyroid cyst. Computarized tomography and magnetic resonance are of great importance in its diagnosis, but sometimes is found within surgery or in the anatomopathologic study.
