  • The parathyroid adenoma is the most common cause of the primary hyperparathyroidism. The characteristic of primary hyperparathyroidism is hypercalcemia and high value of serum parathyroid hormone. The primary hyperparathyroidism with parathyroid adenoma is treated by excision of parathyroid gland involved. Especially, parathyroid storm in patients with primary hyperparathyroidism is more prevalent than commonly appreciated. The symptoms and signs of the syndrome are not only due to the hypercalcemia, but also to the toxic effects of the parathyroid hormone. Its wide, but nonspecific clinical presentations make it easily confused with other cardiovascular or renal diseases. The mortality rate in untreated cases of parathyroid storm is essentially 40%. A 33 year old woman with primary hyperparathyroidism was found to have a left lower parathyroid adenoma, presented with hypercalcemic crisis. Initially, good responsiveness to a saline infusion, furosemide administration was noted. Unfortunately, she became consciousness disturbance after fine-needle aspiration of the parathyroid tumor. The recurrent storm was refractory to medical therapy, but was treated succesfully by emergent surgical removal tumor revealed a parathyroid adenoma with parathyroid hormone. Hypercalcemia was alleviated postoperatively. These observations corroborated a functioning parathyroid adenoma.

  • Background and Objectives : Parathyroid adenoma is a rare disease in Korea, but the incidence of parathyroid adenoma has gradually increased due to generalized measurement of serum calcium and imaging study according to wide spread public health screening program. In previous researches, the analysis of clinical aspects were insufficient due to a few cases. The purpose of this study was to assess the clinical analysis of surgically treated parathyroid adenoma with hyperparathyroidism. Methods : We reviewed the medical records of nineteen cases of parathyroid adenoma with hyperparathyroidism. Initial symptom to visit hospital, hypercalcemia associated medical symptom, surgical outcome and complication were investigated. Serum total calcium, parathyroid hormone, phosphate, alkaline phosphatase were checked before and after surgery. Imaging study was performed with combination of radionuclide parathyroid scan, ultrasonography and neck CT scan. Results : The initial symptoms were no symptom(6/19), pelvic pain(5/19), muscular weakness (3/19), bone pain(3/19) and palpable neck mass(2/19) in order of frequency. Serum total calcium, parathyroid hormone decreased and phosphate increased after surgery than before surgery statistically significantly. Sensitivities of parathyroid scan, neck ultrasonography and neck CT as preoperative localization test were 88.2%, 72.7%, 73.3% each. The most common postoperative complication was transient hypocalcemia(9/19). Conclusion : Similar to previous study, parathyroid adenomas have numerous clinical features and surgical treatment via unilateral approach with preoperatively localized single parathyroid adenoma was successful. In our study, parathyroid adenoma was predominantly detected by elevated serum calcium level with no clinical symptom so we need to evaluate parathyroid adenoma, if serum calcium elevated.

  • A case of primary hyperparathyroidism due to parathyroid adenoma is presented. A 14 year-old male was admitted to the hospital comptaining of voiding difficulty. The intravenous pyelogram demonstrated a stone in the proximal one third of the left ureter and marked hydronephrosis of the left kidney. The Tc-99m sestamibi nuclear scan demonstrated a hot spot below the lower pole of the left lobe of the thyroid. Laboratory study demonstrated hypercalcemia (12.4 mg/dL) and elevated parathyroid hormone (143.67 pg/mL). A parathyroid gland located below the lower pole of the left lobe of the thyroid was excised. A parathyroid adenoma, consisting of mainly chief cells was found on pathologic examination. Postoperatively the patient had transient hypocalcemic symptoms, which resolved with administration of calcium preparation and vitamin D.

  • It has become evident in recent years that parathyroid adenoma and well differentiated thyroid cancer occur together more than would be expected by chance alone. However, the association between them is not well understood. We have experienced 4 cases of coexistent parathyroid adenoma and well-differentiated thyroid cancer during the past 16 years. None of them had a familial incidence or a history of radiation exposure. Three cases showed symptomatic hypercalcemia(including renal stones, bone pain, joint pain) and in two of them(patient 1 and patient 2), thyroid abnormalities were detected preoperatively by neck ultrasonography or neck CT for evaluation of parathyroid lesions. However, in patient 3, a parathyoid humor was identified and removed incidentally during the course of thyroidectomy. In 3 cases, surgeries for thyroid carcinoma and parathyroid adenoma were performed during the same exploration of the neck, but in patient 4, thyroidectomy preceded parathyroidectomy; The interval between thyroidectomy and subsequent parathyroidectomy was 11 yeras. The thyroid tumors in 3 cases were papillary carcinoma, the sizes of which ranged from 1.0 cm to 1.5 cm in greatest diameter. The remaining case(patient 4) was minimal invasive follicular carcinoma. Total or near-total thyroidectomy with various types of cervical lymphnode dissection and bilateral neck exploration for the parathyroid lesion was performed in 3 cases with papillary carcinoma. Ipsilateral lobectomy and contralateral partial thyroidectomy with consequent unilateral neck exploration for the parathyroid tumor was performed in the case of follicular cancer. In our experience, parathyroid adenoma and well-differentiated thyroid carcinomas can be coexistent and we felt that the attention to the hypercalcemic patients would be needed for detection of this rare condition.

  • In general, the anatomical location and number of parathyroid glands are well known, but they are often found in a variety of locations, making it difficult to find parathyroid glands during surgery. Besides Intra-thyroidal parathyroid adenoma is extremely rare case, and it is harder to identify in surgery. We encountered a 51-year-old patient with a thyroid nodule. The results of the additional blood test and the Tc-99m MIBI were combined to determine that the left lower lobe parathyroid adenoma was highly likely. This patient was treated with left thyroid lobectomy with parathyroid identification using Near-infrared (NIR) imaging. Afterwards, the biopsy confirmed that it was a parathyroid adenoma, and has since been monitored through outpatient observation without any problem. We present this rare case with a review of related literatures.

  • Parathyroid adenoma can cause extracapsular bleeding. In 1934, Capps first reported a case of massive hemorrhage secondary to rupture of a parathyroid adenoma. Recently, we experienced a 73-year-old female presented with pharyngeal discomfort and extensive ecchymosis over the neck without history of trauma. Endoscopic investigation revealed submucosal hemorrhage in the posterior wall of the hypopharynx. CT scan and ultrasonography demonstrated the presence of a mass below the left thyroid lobe. Serum calcium level was normal and PTH level was elevated. We underwent left thyroidectomy and parathyroidectomy 2 weeks later from first visit. During the operation, hypopharyngeal mucosa was teared and it was treated with pharyngostoma formation and L-tube feeding. We report a rare case of normocalcemic parathyroid adenoma with spontaneous hemorrhage and propose the proper management period with a literature review.

  • Cystic parathyroid adenoma is one of rare causes of hyperparathyroidism, and tends to cause increased serum level of parathyroid hormone, alkaline phosphate and serum calcium level similar to when compared to those of solid adenoma. The possibility of a coincidental appearance of primary hyperparathyrodism and nonmedullary thyroid cancer is rare, and often neglected. A 40-year-old female presented with constipation and weight loss for 3 months. The serum calcium, phosphate and alkaline phosphate were 16.6 mg/dl, 2.2 mg/dl and 505 IU/L respectively and serum parathyroid hormone level was 1556.2 pg/mL. Neck US showed mixed nodules at both thyroid lobes, and PET-CT showed a right thyroid nodule without FDG uptake. The patient was diagnosed of primary hyperparathyroidism and underwent parathyroidectomy and a total thyroidectomy. Histopathologic results revealed parathyroid adenoma with cystic change (2 cm greater diameter) in the right lower parathyroid gland and coexistent papillary carcinoma of the right lobe of thyroid gland (infiltrating, 0.3 cm in greater diameter). She remained well and serum calcium, phosphate, parathyroid hormone level were normalized within 24 hours.

  • Primary hryperparathyroidism is a relatively rare disease entity in Korea. It's characterized by severe skeletal and renal changes due to hypersecretion of parathyroid hormone, and rarely shows peptic ulceration, hypertension, pancreatitis and impaired mentality. Recently the determination of the serum calcium level has become a routine laboratory test and the awareness of primary hyperparathyroidism has been incerased, the disease is being diagnosed with increasing frequency. Primary hyperparathyroidism is most commonly caused by parathyroid adenoma and rarely hyperplasia, cancer of parathyroid glands. The authors operated sucessfully a case of primary parathyroid adenoma by diagnosed by nuclear medical diagnostic work-up. The patient had anterior neck mass(soft, non tender nodule) on physical examination, multiple goiter on thyroid ultrasonogram and scan. The parathyroid lesion was difficult to find preoperatively.

  • A 65-year-old patient who underwent total thyroidectomy 10 years ago was suspected of having a parathyroid adenoma, and minimally invasive parathyroidectomy was planned. Preoperative ultrasonography(USG) and 99mTc MIBI scan indicated a left lower parathyroid lesion. In the first operation, intraoperative parathyroid hormone monitoring (IOPTH) was not possible due to hospital circumstances. Although no adenomatous lesion was found in the expected surgical field, surgery was completed after removing lesions around the left lower parathyroid gland. However, post-surgery, parathyroid hormone did not decrease at all, so a second operation was performed with IOPTH preparation. In the second operation, intraoperative ultrasonography was performed, and a suspected adenoma lesion was removed from the left upper lesion. He has been under follow-up for 3 years without complications. Surgeon-peformed intraoperative USG and preoperative scintigraphy had advantages in determining the localization of parathyroid lesion even withiout IOPTH.

  • In thyroid and parathyroid surgery, damage to the recurrent laryngeal nerve(RLN) is the most common iatrogenic cause of vocal cord paralysis. Identification and preservation of the BLNs and meticulous technique can siginificantly decrease the incidence of this complication. We experienced one case of NRRLN in a patient with the parathyroid adenoma. During the dissection, there was no branch to be considered as RLN in tracheoesophageal groove. While searching for the RLN, We found a white structure coursing horizontally at the level of cricoid cartilage directly arising from the vagus nerve in the carotid sheath. That structure was nonrecurrent recurrent laryngeal nerve(NRRLN) and NRRLNs are exceedingly rare. Awareness of the possibility of NRRLN will prevent the surgeon from accidentally severing one if it is encountered during surgery.
