RT Journal Article SR Electronic T1 Ectopic Parathyroid Adenoma in the Carotid Sheath JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 201 OP 202 DO 10.2967/jnmt.115.170993 VO 44 IS 3 A1 Christopher D. Sanders A1 Jared D. Kirkland A1 Ely A. Wolin YR 2016 UL http://tech.snmjournals.org/content/44/3/201.abstract AB Primary hyperparathyroidism is predominantly caused by a single parathyroid adenoma. Knowledge of normal and ectopic locations of parathyroid glands is crucial to help guide surgeons who plan targeted unilateral parathyroidectomy to reduce surgical time and risk. We describe a female patient with clinical primary hyperparathyroidism who underwent a failed initial parathyroidectomy, with subsequent imaging localizing an ectopic parathyroid adenoma in the carotid sheath.
