Infected Thyroglossal Duct Cyst Involving Submandibular Region: A Case Report

Abstract

Thyroglossal duct cyst presents most frequently in the midline of the neck, either at or just below the level of the hyoid bone. They generally manifest as painless neck swelling, and they move on protrusion of tongue and during swallowing. A case of thyroglossal cyst was reported in the left submandibular region in a 14-year-old girl, above the level of hyoid bone; ultrasound examination favored a cystic lesion which moved in a vertical fashion on swallowing whereas fine needle aspiration cytology report was suggestive of simple cystic lesion of thyroglossal cyst. No lymphoid or malignant cells were present. The cyst was excised completely by surgical procedure under general anesthesia. Histopathological analysis revealed thyroglossal cyst showing columnar and flattened epithelium of cyst with focal aggregate of chronic inflammatory cells supported by fibrocollagenous cyst wall. The clinical, ultrasound, and histopathological findings suggested that the lesion was an infected thyroglossal cyst. There was no evidence of recurrence 6 months after surgery.

The prevalence of thyroglossal tract thyroid tissue on SPECT/CT following 131I ablation therapy after total thyroidectomy for thyroid cancer

“…The superiority of SPECT/CT in delineating this tissue is highlighted by substantial interobserver agreement compared with only fair interobserver agreement on planar imaging. The actual prevalence of thyroglossal tract thyroid tissue may be even higher given that thyroglossal duct cysts have been reported to occur more than 1 cm from the midline, and activity more lateral than 1 cm was classified as negative using our definition. Our results also suggest that, when present, this tissue contributes to a significant amount of total neck RAI activity on planar imaging.…”

Correlations between ultrasonography performed by the ENT specialist and pathologic findings in the management of three cases with thyroglossal duct cyst

“…Moreover, these are reported complex cases with unusual presentations such as submental-intralingual [3], in hyoid bone [4], or intralaryngeal [5] as in the third case we presented. Often TDC is discovered as infected [6] or as giant cervical masses [7] causing stridor, as in our second case, or obstructive sleep apnea [8]. There are cases presenting simultaneous cysts [9] and synchronous tumors [10].…”
