The case emphasizes the importance of considering uncommon etiologies, such as congenital anomalies, as a differential diagnosis when evaluating pediatric neck masses. The patient was prescribed broad-spectrum antibiotics, which led to the regression of the mass and inflammatory signs. Close follow-up in endocrinology and otorhinolaryngology appointments was maintained, and after 7 months, hypoplasia of the left lobe was observed. Thyroid function was reevaluated, and after two years, no recurrences were noted. The case highlights the significance of a comprehensive examination and assessment of corresponding clinical features, which can significantly reduce the rate of misdiagnoses and achieve an individualized diagnosis.<\/jats:p>","DOI":"10.3389\/fped.2023.1212767","type":"journal-article","created":{"date-parts":[[2023,7,7]],"date-time":"2023-07-07T17:55:20Z","timestamp":1688752520000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Case report: Fourth branchial cleft cyst: a case of acute suppurative thyroiditis"],"prefix":"10.3389","volume":"11","author":[{"given":"M.
