Introduction. Thyroglossal duct cysts are developmental, epithelial lesions
localized in the neck's median line. They occur mainly in children and
adolescents, however, also in 1/3 of patients older than 20 years of age.
Symptoms dependent on the size and location along the path of the
thyroglossal duct. Case outline. This article presents a case, with
diagnostic imaging and surgical treatment, of a two-year-old girl
hospitalized due to dyspnea, caused by a large cyst localized at the base of
the tongue during an upper respiratory tract infection. Before surgery,
biochemical examinations diagnostic imaging were performed to exclude
ectopic thyroid tissue. Surgery was performed applying Sistrunk's procedure,
which entailed excising the cyst's tissue at its origin. Conclusion. In
patients presenting with thyroglossal duct cysts, upper respiratory tract
infections increase the probability of discovering previously existing
cysts. A cyst localized around the foramen cecum can cause inspiratory and
expiratory dyspnea.
