SSTR Expressing Mediastinal Ectopic Thyroid: A Rarity Unveiled.

Abstract

Rarely, ectopic thyroid tissue can coexist with an eutopic thyroid. Technetium pertechnetate scan is peculiar for thyroid tissue uptake. However, DOTANOC uptake in mediastinal ectopic thyroid has been rarely reported. We present a unique case of an ectopic mediastinal thyroid mass that did not show any uptake on a pertechnetate scan and showed significantly increased uptake on ⁶⁸Ga-DOTANOC positron emission tomography-computed tomography with an eutopic cervical thyroid with normal pertechnetate and physiological mild DOTANOC uptake.
