Ectopic thyroid tissue: unusual differential diagnosis of cervical paraganglioma

Ectopic thyroid tissue: unusual differential diagnosis of cervical paraganglioma

Ectopic thyroid tissue (ETT) lateral to the midline is rare. Its occurrence in the carotid bifurcation is exceptional. We present a 45 years woman who consulted with a slow growing right cervical swelling. Clinical examination Ultrasonography, contrast enhanced CT and cervical MRI concluded to a paraganglioma. Intra-operatively, the tumor didn't have the characteristic aspect of a paraganglioma...

Cervical paraganglioma presenting as thyroid neoplasia.

Ectopic cervical thymic tissue: diagnosis by fine needle aspiration.

Cervical thymic masses are congenital lesions that result from aberrant thymic migration during embryogenesis. Although most of these masses are asymptomatic, they may cause debilitating symptoms secondary to encroachment on adjacent aerodigestive structures. Preoperative diagnosis of ectopic thymic tissue is rare; most cases are clinically misinterpreted as branchial cleft remnants or cystic h...

Lateral cervical ectopic thyroid masses with eutopic multinodular goiter: an unusual presentation.

Multiple thyroid ectopia with a normally located thyroid gland is a very rare condition. We present a 34-year old Nigerian woman who had had anterior and left-sided lateral neck swellings for the past 15 years. She was clinically euthyroid and thyroid function test results were normal. Neck ultrasonography revealed multinodular goiter with extension to the left pre-auricular area. Fine Needle A...

Ectopic Sequestered Thyroid Tissue: An Unusual Cause of a Mediastinal Mass

An 80-year-old female presented with an incidental finding of a retrosternal mass on magnetic resonance imaging. Ultrasound demonstrated a mediastinal lesion adjacent to but separate from the inferior pole of the right thyroid lobe. Fine needle aspiration cytology demonstrated colloid and follicular cells. At surgery, the right thyroid lobe was found to be normal. A discrete 5 cm nodule was fou...
