OBJECTIVES To evaluate the ability of surgeons to predict the laterality of parathyroid adenomas from technetium Tc 99m sestamibi scans and compare their results with the radiologic interpretations. DESIGN Retrospective medical record review with single- blinded review of sestamibi scans. SETTING Tertiary care academic medical center PATIENTS The study population included 110 consecutive ...

Ectopic parathyroid adenomas can be encountered during four gland explorations, but nearly 80% of adenomas are localized with ultrasound and sestamibi imaging. Ectopic adenomas are thought to arise from abnormal migration during development. As a cervical congenital anomaly, common carotid artery agenesis is an extremely rare anomaly characterized by separate origins of the internal and externa...

Background. Parathyroid adenoma is the commonest cause of primary hypercalcaemia and usually presents with symptoms/signs of hypercalcaemia. This paper highlights an unusual presentation. Case Report. A 27-year-old female presented with a painful left mandibular swelling, suspicious of neoplasia. A computed tomography (CT) guided biopsy was performed. Based on the histology result, serum calciu...

A 50-year-old woman with a maxillary giant cell tumor had primary hyperparathyroidism from a mediastinal parathyroid adenoma. Computed tomography showed a mildly enhanced, oval soft tissue nodule (2.5 × 1.5 × 1.7 cm) at the anterosuperior mediastinum. Mediastinal parathyroidectomy was performed with a 3-arm surgical robot. After surgery, the plasma parathyroid hormone level decreased markedly (...

BACKGROUND Primary hyperparathyroidism is caused by the excessive growth of parathormone secretion, its consequence being hypercalcemia. The parathyroid adenoma is responsible for over half of primary hyperparathyroidism cases. The mandibular tumor can be the initial sign in the case of primary hyperparathyroidism. CASE PRESENTATION We present the case of a 33 year old patient with history of...

Brown tumors are considered one of the most pathognomonic skeletal changes that accompany primary hyperparathyroidism (PHPT). It results from excessive secretion of parathyroid hormone (parathormone or PTH). The mandible is the most involved facial bone by brown tumor. Ectopic located parathyroid adenoma is uncommon, and thus, its diagnosis and management can sometimes be challenging. Difficult...

AN UNEXPECTED HYPERPARATHYROIDISM AS A CONSEQUENCE OF RADICAL TREATMENT OF PRIMARY HYPERPARATHYROIDISM (Abstract): The possibility of a rebound of the parathyroid hormone (PTH) plasma level after a temporary return to the physiological range following the ablation of a parathyroid adenoma is a well known phenomenon; on the opposite, the pathogenesis until now is not completely clear. This resea...
