INTRODUCTION The spontaneous rupture of a parathyroid adenoma accompanied by extracapsular hemorrhage is a rare, potentially fatal, condition and is a cervicomediastinal surgical emergency. CASE PRESENTATION This report describes an atypical two-step spontaneous rupture of an asymptomatic parathyroid adenoma in a 56-year-old Caucasian woman who presented with a painful mass in the right side ...

Introduction Phaeochromocytoma may occasionally induce hypercalcaemia. Case reports of correction of hypercalcaemia by surgical removal of the phaeochromocytoma indicate the importance of humoral mechanisms (Swinton, Clerkin and Flint, 1972; Kukreja et al., 1973). Kukreja et al. (1973) noted a pre-operative elevation of serum immuno-reactive parathyroid hormone (i-PTH) implying that hypercalcae...

Objectives. We compared five parathyroid scintigraphy protocols in patients with primary (pHPT) and secondary hyperparathyroidism (sHPT) and studied the interobserver agreement. The dual-tracer method ((99m)Tc-sestamibi/(123)I) was used with three acquisition techniques (parallel-hole planar, pinhole planar, and SPECT/CT). The single-tracer method ((99m)Tc-sestamibi) was used with two acquisiti...

The incidence of parathyroid carcinoma is rare. We recently encountered a case of double carcinoma, located in the right and left upper parathyroid glands. A 67-year old man came to the Teikyo University Hospital because of his bilateral parathyroid masses with hypercalcemia and high parathyroid hormone (PTH). Preoperative diagnoses were parathyroid adenoma in the left lobe and papillary thyroi...

We measured pre- and post-dialysis concentrations of ionized calcium (iCa) in whole blood, total calcium (tCa) in plasma, and intact parathyrin (PTH) in serum of 19 patients undergoing maintenance hemodialysis. Plasma tCa was inappropriately increased relative to iCa in 63% of the specimens; the iCa correlated with the PTH concentration in 12 of 19 pre-dialysis specimens, whereas tCa correlated...

Thyroid surgery is a widely performed operation in recent two decades with complication rate less than 5% [1]. Parathyroid damage is most frequent complication of thyroid surgery because parathyroid is near to or even inside of thyroid gland, and because it is a challenge to distinguish by naked eyes. It has been reported that the incidental rate of parathyroidectomy in thyroid surgery ranges b...

recently, a number of procedures for interventional radiology diagnosis and treatment have been developed by the radiologists. the ‘interventional radiology’ refers to the therapeutic procedures performed under imaging guidance. the emergence of this specialty has been made possible by a lot of advances in the technology, imaging systems, and radiologists experience. interventional radiologists...

Abstract Thyroid cancer ranks as the leading endocrine malignancy in adults. The foundation for primary diagnosis of thyroid is a high-resolution ultrasound (US) gland including US-guided fine-needle biopsy (FNB) suspected nodules. Advanced cross-sectional imaging, computed tomography (CT), magnetic resonance and positron emission tomography, can be useful selected patients. mainstay treatment ...

Parathyroid glands from cases of hyperparathyroidism have been examined with particular attention to mast cells. In ;normal' glands accompanying an adenoma they were common, although there was a wide range in their frequency, whereas in pathological tissue, both adenoma and hyperplasia, mast cells were scarce. This difference between glands was examined with respect to alterations in gland size...
