Enlarged hemorrhagic lingual thyroid managed with transoral robotic surgery.

Purpose: Lingual thyroid glands are rare embryologic variants of undescended tissue centered in the base of the tongue. Despite notable size, many lingual thyroids can be asymptomatic, though intervention is warranted for progressive or emergent symptoms. We report a rare manifestation of a hemorrhagic lingual thyroid addressed with both interventional radiology and robotic techniques.

Methods: A previously asymptomatic 41-year old female presented to the emergency department with massive hematemesis after significant binge drinking and vomiting. Emergent intubation was performed and gastroenterology workup ruled out Mallory-Weiss tears or ruptured esophageal varices. Fiberoptic laryngoscopy and imaging revealed a bleeding tongue base mass concerning for malignancy.

Results: Aberrant feeding vessels with identifiable blush were embolized by Neurointerventional Radiology and the patient underwent tracheostomy for airway protection. Lingual thyroid was confirmed by biopsy and the mass was definitively resected via transoral robotic surgery. The patient had no further bleeding events and was decannulated uneventfully.

Conclusions: Lingual thyroid glands can present with life-threatening hematemesis and obstruction that may masquerade as entities of vascular or neoplastic origin. Management encompasses multidisciplinary diagnostic confirmation, airway protection, and minimally invasive resection that minimizes functional morbidity.
