The carotid arteries, classically described as taking a relatively straight course through the
neck, deviate medially in a minority of patients. At the extreme, the internal carotid arteries …

We read with interest the article by Steinl et al 1 discussing the simultaneous detection of
retropharyngeal carotid arteries (CAs) and parathyroid adenomas in 5 patients. At our …

Ectopic parathyroid adenomas can be encountered during four gland explorations, but
nearly 80% of adenomas are localized with ultrasound and sestamibi imaging. Ectopic …

Primary hyperparathyroidism is predominantly caused by a single parathyroid adenoma.
Knowledge of normal and ectopic locations of parathyroid glands is crucial to help guide …

A 66-year-old female underwent preoperative evaluation for primary hyperparathyroidism.
Ultrasound (US) neck and technetium (Tc)-99m-sestamibi planar scintigraphy were …

A 76-year-old woman was referred to our hospital for evaluation of a parathyroid adenoma,
detected on sonography. It had been located posteroinferiorly to the right thyroid lobe …

During routine dissection of the neck region of a middle aged female cadaver, the
brachiocephalic trunk was found to arise from the arch of the aorta along the left margin of …

Although interpatient variations in the course and anatomy of extracranial internal carotid
arteries (EICAs) have been described previously, intrapatient variability is rarely cited in the …

We report the imaging features of an occult parathyroid adenoma with unusual location in
the carotid sheath. Our patient presented with primary hyperparathyroidism. Following …

BACKGROUND AND PURPOSE: Retropharyngeal carotid arteries are a clinically relevant
anatomic variant. Prior studies have documented their incidence, but only a single case …
