ABSTRACT A 7 yr old female spayed Canaan dog was presented for evaluation of a subclinical intrathoracic mass noted during meta-static staging for a digit and lingual mass. Thoracic ultrasound and computed tomography revealed a 6.0 × 5.5 cm mass within the cranial mediastinum. The mass was septated with mixed fluid and soft-tissue structures and no evidence of vascular invasion. Narrow excision of the mass via a sternal thoracotomy was performed. Histopathology of the mass was consistent with a thyroglossal duct cyst adenocarcinoma. This is the first reported case of a thyroglossal duct cyst adenocarcinoma arising in the cranial mediastinum of a dog. There was no evidence of metastasis or recurrence 25 mo after surgery and adjunctive therapy.

Thyroglossal Duct Cysts

Thyroglossal duct cysts (TDC) classically present as midline neck masses in close relation to the hyoid bone; yet—not uncommonly—their locations may be varied from the midline and from the hyoid. By means of the diagnostic modality of computed tomography (CT), high-resolution images of several cases of alternate presentations and locations of the TDC are examined. Included are examples of TDC in the suprahyoid, transhyoid, infrahyoid, and lateral positions. The potential value of CT in the diagnosis of the unusual cyst will be demonstrated and discussed.

Rule Out

A 2 yr old dog presented for dysphagia and coughing secondary to a 4 cm × 4 cm turgid subepiglottic mass. Cervical radiographs, an esophagram, and computed tomography confirmed the presence of a cystic mass that was not intimately associated with any surrounding structures. An incisional biopsy confirmed the cystic nature of the mass and helped to rule out a malignancy. A marginal surgical excision was performed via a ventral approach. Histopathology of the mass was consistent with a thyroglossal duct cyst. This is the first report of a thyroglossal duct cyst in this location in a dog. There was no recurrence of clinical signs 14 mo after surgery.

Unusual Location

An atypically sited thyroglossal cyst in a 69-year-old woman is described in this report. The cysts may be located in the intralingual, suprahyoid, thyrohyoid or suprasternal region. The intrahyoid location is rare. The diagnosis was confirmed by computed tomography (CT). Surgical procedure should be indicated in intrahyoid thyroglossal duct cyst cases.

Ectopic Thyroid Tissue

Thyroglossal duct cysts are typically benign and usually asymptomatic. Malignant transformation is uncommon. Intralaryngeal extension is rare and results in dysphonia or dyspnea. There is no literature nowadays reporting the thyroglossal duct cyst carcinoma combining the clinical features of intralaryngeal extension. The authors present a case of progressive hoarseness and midline neck mass for 2 years. The laryngoscope and computed tomography revealed a 6-cm thyroglossal duct cyst containing ectopic thyroid tissue with intralaryngeal extension and causing airway obstruction. Complete excision with Sistrunk operation revealed papillary thyroid carcinoma. The patient resumed normal phonation after the surgery. There was no evidence of tumor recurrence and no hoarseness or dyspnea at 6 months follow up. This is the first reported case of a huge thyroglossal duct cyst carcinoma with intralaryngeal extension causing airway compromise. Complete excision of tumor is essential and vital to the symptom relief. A thyroglossal duct cyst carcinoma with endolaryngeal involvement should be considered in the differential diagnosis when the case has a massive midline neck mass with ectopic thyroid tissue and develops dyspnea or hoarseness concurrently.
