“…[3,5,6] Ectopic parathyroid adenoma can represent a diagnostic dilemma, in a scenario like our reported case, a case reported by Malm et al described a mass which was suspicious for carotid body tumor and turned to be an ectopic parathyroid adenoma in the carotid sheath. [7] In an analysis of 202 patients with ectopic parathyroid adenoma, Roy et al reported an overall sensitivity of preoperative MIBI scans and ultrasound scan for detecting ectopic glands of 89% and 59% respectively. [3] However, in the same analysis, there was no imaging modality with a high rate of detecting ectopic glands in the carotid sheath, as the ultrasound sensitivity was 0% and the MIBI scan sensitivity was only 20%.…”

Parathyroid glands are four small-sized glands, located behind the upper and lower poles of the thyroid gland. The two superior glands are usually located at the posterolateral aspect of the upper pole of the thyroid whereas the inferior glands are found frequently near the lower thyroid pole. However, parathyroid glands can be found in ectopic positions in 6%-16% of normal adults. [1] These ectopic positions include intrathyroidal, [1,2] carotid sheath, [1] retroesophageal sites, mediastinal sites, and thymus. [1][2][3] Compared to the superior parathyroid glands the inferior glands demonstrate a greater degree of variability in location since they might stopover anywhere along the thyrothymic tract as they descend with the thymus gland from the angle of the mandible down to the pericardium during embryogenesis. [4] Parathyroid adenomas can be found in various ectopic positions including the carotid sheath. We report a 52-year-old Libyan woman who presented with neck mass and a fragility fracture. Her serum Calcium was elevated (14.3 mg/dl), as well as her parathyroid hormone (1202 pg/ml). Technetium-99m-sestamibi scan showed a large localized parathyroid adenoma at the upper lateral left aspect of the neck just below the left submandibular gland. The patient underwent surgical resection, and the histopathology confirmed the diagnosis of parathyroid adenoma.The rarity of the ectopic parathyroid adenoma in the carotid sheath led to a delayed diagnosis of this case. Therefore, ectopic parathyroid adenoma should be considered in the differential diagnosis of masses that arise from the carotid sheath.

The aim of this study was to examine the course of the carotid artery (CA) and define CA anomalies important for neck surgery using conventional and three-dimensional computer tomography (3D CT). This was designed as an observational study with retrospective CT and 3D CT angiography analysis. 4,000 CAs depicted on 2,000 CT angiographies were analyzed to determine the relationship of common, internal, and external portions of the CA to the neck organs, with special emphasis on the thyroid gland area and organs involved in the neck dissection surgery. A total of 47 out of 4,000 imaged CAs had congenital anomalies (1.18%). These anomalies were found in 45 patients, unilaterally in 33 and bilaterally in two. The level of the common CA bifurcation to internal and external CAs was rarely abnormal. It was at the level of C5 and C6 in two cases only (0.05%). The common CA, either aberrant or tortuous, ran abnormally close to the thyroid gland in 22 cases (0.55%). In planning neck dissection surgery, laryngectomy, or thyroidectomy, the surgeon should bear in mind that CA anomalies are present in approximately 1.2% of cases. Preoperative conventional CT angiography or 3D CT allows precise identification of anomalous CAs, thereby reducing the possible risk of intraoperative injury.

In an attempt to describe the morphofunctional consequences of uni- and bilateral aplasia of the common carotid artery (CCA), which is usually a vascular source of the external carotid (ECA) and internal carotid (ICA) arteries, we investigated online databases of anatomical and clinical papers published from the 18th century to the present day. We found 87 recorded cases of uni- and bilateral CCA aplasia in subjects from the first hours to the eighth decade of life, which had been discovered in 14 (known) countries. Four crucial parameters were described: the embryology of the carotid arteries, morphophysiology of the carotid arteries, CCA aplasia, and unilateral versus bilateral CCA aplasia, including history, general data, diagnosing, vascular sources, caliber, course of the separated ECA and ICA, associated vascular variants, and pathological disorders. To complete the knowledge of the morphofunctional consequences of the absence of some artery of the carotid system, and risking the possibility of repeating some words, as “carotid artery”, or “carotid aplasia” and the headings from our previous article about bilateral ICA absence, this review is the first in the literature that recorded all cases of the CCA aplasia published and/or cited for the past 233 years. Main characteristic of the CCA absence is its association with 21 different diseases, among which the aneurysms were in 13.69% of cases, and 17.80% of cases were without pathology.
