Ectopic thyroid results from a migration defect of the developing gland during embryogenesis causing congenital hypothyroidism. But it has also been detected in asymptomatic individuals. This study aimed to investigate the histopathological, functional, and genetic features of human ectopic thyroids. Six samples were histologically examined, and the expression of the specific thyroid proteins w...

Mediastinal ectopic thyroid is quite rare, occurring in less than 1% of all ectopic thyroids. Frequent location of mediastinal ectopic thyroid in reported cases is anterosuperior mediastinum. CT findings of ectopic thyroid can be various and are dependent on several factors, such as its iodine content, the extent of tissue degeneration, and the presence of colloid cysts. This is a case of right...

Rationale: Ectopic thyroid is commonly found in the neck region. Intra-abdominal ectopic thyroid is extremely rare, with only 2 cases reported in the pancreatic region. Very few reports have described detailed imaging findings of intra-abdominal ectopic thyroid. Patientconcerns:A 73-year-old womanwith aggravated recurrent right upper quadrant pain was found to have a retroperitoneal mass at the...

Ectopic thyroid can be encountered anywhere between the base of tongue and pretracheal region. The most common form is euthyroid neck mass. Herein, we aimed to present the findings of a female case with ectopic thyroid tissue localized in the left submandibular region. A 44-year-old female patient, who underwent bilateral subtotal thyroidectomy four years ago with the diagnosis of multinodular ...

BACKGROUND Ectopic thyroid tissue very rarely occurs in the buccal region. Even more rarely encountered is the papillary carcinoma arising in the ectopic tissue. METHODS AND RESULTS We herein present a 78-year-old female patient admitted with a giant, buccal mass that developed within the previous 2 years. Physical examination revealed a vegetative mass on the left buccal region without any c...

We present a case of a left-sided neck mass in an 8-year-old female that proved to be ectopic thyroid tissue. After excision, this patient continues to do well and is euthyroid without recurrence after 8-year follow-up. This is a very rare anomaly in a child, especially in conjunction with a normally located thyroid that is functional. We reviewed the literature of displaced ectopic thyroid tis...

Ectopic thyroid tissue is a rare congenital anomaly with extremely rare occurrence of dual ectopy. Authors present a case of a 13 year-old girl with anterior neck swelling since one year. Contrast enhanced CT demonstrated absence of normally located, bilobed thyroid gland, Instead two foci of ectopic thyroid tissue were seen in the lingual and pretracheal region. Imaging workup is of great valu...

Ectopic thyroid tissue in the adrenal gland (ETTAG) usually presents as a well-circumscribed cystic mass on a CT scan. However, the MRI features of ETTAG are incompletely understood. We report a case of ectopic thyroid tissue in the adrenal gland, which demonstrates findings similar to those of a pheochromocytoma on the MRI.
