Brown tumors are erosive bony lesions caused by chronic excessive secretion of parathyroid hormone. Since the introduction of routine calcium measurement, the diagnosis of hyperparathyroidism has usually been made in asymptomatic patients and as a result, brown tumors are rarely observed as an initial manifestation of hyperparathyroidism. We report the case of a 70-year-old woman who presented with right wrist pain. A roentgenogram showed erosive bone tumors of the ulna and radius, which were mistaken for primary or metastatic bone tumors. Extensive workups were performed to determine the cause(s); however, these lesions were finally diagnosed as brown tumors associated with primary hyperparathyroidism due to a parathyroid adenoma. This case illustrates the diagnostic pitfall in patients who present with skeletal manifestations of hyperparathyroidism and the need for vigilance and a high level of suspicion by physicians.

Secondary hyperparathyroidism is the condition is which increased parathyroid hormone(PTH) is secreted to compensate for a chronically low calcium level and chronic renal failure is the most common cause. In 1934, Albreight reported an assocition between hyperparathyroidism and the chronic renal failure and in 1960, stanbury first reported subtotal parathyroidectomy in the treatment of secondary hyperparathyroidism. The physiologic mechanisms leading to secondary hyperparathyroidism in the chronic renal failure are well known and relatively well controled with medical management, but sometimes may necessitate surgical intervention in medically intractable cases. In Korea, the surgery of secondry hyperparathyroidism is not frequently done yet as in western countries. We experienced two cases of secondary hyperparathyroidism recently and report its results of subtotal parathyroidectomy.

Purpose: Patients with secondary hyperparathyroidism are at high risk for developing postoperative hypocalcemia. However, there are limited data regarding predictors of postoperative hypocalcemia in renal failure patient with secondary hyperparathyroidism. This study aimed to determine the clinical presentations of renal hyperparathyroidism and the predictors of early postoperative hypocalcemia after total parathyroidectomy. Methods: Data of patients with renal hyperparathyroidism who underwent total parathyroidectomy between January 2007 to December 2014 were reviewed retrospectively. Patients were divided into 2 cohort groups according to their serum calcium levels within 24 hours of parathyroidectomy: the hypocalcemia group (calcium levels of 2 mmol/L or less), and the normocalcemia group (calcium levels more than 2 mmol/L). With the use of multivariable logistic regression analyses, the predictors of early postoperative hypocalcemia after total parathyroidectomy in patients with renal hyperparathyroidism were investigated. Results: Among 68 patients, 56 patients (82.4%) were symptomatic preoperatively. Fifty patients (73.5%) presented with bone pain and 14 patients (20.6%) had muscle weakness. Early postoperative hypocalcemia occurred in 25 patients (36.8%). Preoperative alkaline phosphatase level was the predictor of early postoperative hypocalcemia (adjusted odds ratio, 1.004; 95% confidence interval, 1.001–1.006; P = 0.002). Conclusion: Results from our study show that most of the patients with renal hyperparathyroidism were symptomatic preoperatively and the most common clinical presentations were bone pain and muscle weakness. The significant predictor of early postoperative hypocalcemia after total parathyroidectomy was the preoperative alkaline phosphatase levels.

Sonmez, Erkin,Tezcaner, Tugan,Coven, Ilker,Terzi, Aysen The Korean Neurosurgical Society 2015 Journal of Korean neurosurgical society Vol.58 No.4

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally. Skeletal involvement such as generalized osteopenia, bone resorption, bone cysts and Brown tumors are seen on the late phase of hyperparathyroidism. The symptoms include axial pain, radiculopathy, myelopathy and myeloradiculopathy according to their locations. Plasmocytoma, lymphoma, giant cell tumors and metastates should be ruled out in the differential diagnosis of Brown tumors. Treatment of Brown tumors involve both the management of hyperparathyroidism and neural decompression. The authors report a very rare spinal Brown tumor case, arisen as the initial manifestation of primary hyperparathyroidism that leads to acute paraparesis.

Deng Erya,Jiang Tingting,Chai Huihui,Weng Ning,He Hongfeng,Zhang Zhengxian,Peng Chengzhong,Yue Wenwen,Xu Huixiong 대한영상의학회 2024 Korean Journal of Radiology Vol.25 No.3

Objective: To prospectively evaluate the outcomes of ultrasound (US)-guided radiofrequency ablation (RFA) in tertiary hyperparathyroidism (THPT). Materials and Methods: Patients with THPT underwent RFA between September 2017 and January 2022. Laboratory parameters, including serum intact parathyroid hormone (iPTH) levels, were monitored for 48 months after RFA and compared with the levels at baseline. Complications related to RFA and changes in hyperparathyroidism-related clinical symptoms were recorded before and after RFA. Results: A total of 42 patients with THPT were recruited for this study. Ultimately, 36 patients with renal failure and 2 patients who underwent successful renal transplantation (male:female, 17:21; median age, 54.5 years) were enrolled. The follow-up time was 21.5 ± 19.0 months in the 36 patients with renal failure. In these 36 patients, iPTH levels were significantly decreased to 261.1 pg/mL at 48 months compared with the baseline value of 1284.9 pg/mL (P = 0.012). Persistent hyperparathyroidism, defined as iPTH levels maintained at > 585.0 pg/mL for 6 months after treatment, occurred in 4.0% of patients (1/25). Recurrent hyperparathyroidism, defined as iPTH levels > 585.0 pg/mL after 6 months, were 4.0% (1/25) and 0.0% (0/9) at 6 months and 4 years after treatment, respectively. In two patients with THPT after successful renal transplantation, iPTH decreased from the baseline value of 242.5 and 115.9 pg/mL to 171.0 and 62.0 pg/mL at 6 months after treatment. All complications resolved within 6 months of ablation without medical intervention, except in 10.5% (4/38) patients with permanent hypocalcemia. The overall symptom recovery rate was 58.8% (10/17). The severity scores for bone pain, arthralgia, and itchy skin associated with hyperparathyroidism improved after treatment (P < 0.05). Conclusion: US-guided RFA is an effective and safe alternative to surgery in the treatment of patients with TPTH and improves hyperparathyroidism-related clinical symptoms.

Background and Objectives Most secondary hyperparathyroidism is caused by chronic kidney disease. The purpose of this study is to evaluate the effectiveness of subtotal parathyroidectomy in the surgical treatment of renal hyperparathyroidism. Subjects and Method We studied twelve patients with renal hyperparathyroidism who underwent parathyroidectomy from Dec. 2002 to Mar. 2007. We measured the amount of serum, intact parathyroid hormone, calcium, ionized calcium, inorganic phosphorus, and alkaline phosphatase preoperatively and postoperatively. Results Subtotal parathyroidectomy was performed in nine patients, and three enlarged parathyroid glands were removed from three patients. Hyperparathyroidism was observed in four patients (33.3%), normal parathyroid function in six patients (50.0%) and hypoparathyroidism in two patients (16.7%) at 5 years after surgery. All of three patients who had removed three enlarged parathyroid glands showed persistent hyperparathyroidism. Serum ionized calcium was normal in 10 patients and two patients showed hypocalcemia after operation. Conclusion Based on the results of this study, we conclude that subtotal parathyroidectomy may be effective in the surgical treatment of renal hyperparathyroidism. However, further studies are necessary to determine the optimal amount of remnant parathyroid tissue in subtotal parathyroidectomy to maintain normal parathyroid function postoperatively.

원발성 부갑상선 기능항진증의 치료 경험

Purpose: The number of patients diagnosed with primary hyperparathyroidism has been increased owing to the routine biochemical screening of serum calcium since 1970's in the western countries as well as recently in Korea. However, the absolute number of surgically treated patients in Korea is still smaller than other developed countries in the incidence wise, and this could indicate the tendency of relatively late diagnosis and treatment of primary hyperparathyroidism in Korea. This study was performed to investigate the clinical character and post operative results of surgically treated Korean patients. Methods: 80 primary hyperparathyroidism patients surgically treated at Asan Medical Center from Jan 1996 to August 2002 were reviewed retrospectively. Results: The etiological proportion of the primary hyperparathyroidism (single adenoma 80%, hyperplasia or multiple adenoma 10%, MENI 9%, cancer 1%) was similar to the western countries. However, the proportion of the symptomatic patients (82%) to the asymptomatic patients (18%) was much higher compared to the recent data of western countries. 41 patients (single adenoma 36 case, hyperplasia 4 cases, cancer 1case) were followed up more than 3 months after surgery with monitoring the serum calcium and i-PTH. In 23 patients (44%), their i-PTH level was above normal range more than once during follow up period without hypercalcemia. The postoperative serum calcium level was lower and the preoperative i-PTH level was higher in these patients significantly compared to the patients with normal postoperative i-PTH level. The tumor size tended to be larger in these patients but statistically insignificant. These results suggest that these patients had more severe hyperparathyroidism. Conclusion: The proportion of the patients who were symptomatic and has persistent post operative high i-PTH level suggesting severe hyperparathyroidism was relatively high compared to the western countries. Earlier diagnosis and treatment is demanded in Korea. (Korean J Endocrine Surg 2003;3:1-6)

목적: 일차성, 이차성, 삼차성 부갑상선 기능 항진증은 각각 원인과 치료방법 그리고 임상 경과가 서로 다르지만 부갑상선 절제술이 표준치료로 알려져 있다. 본 연구에서는 각각의 부갑상선 항진증의 수술 전후의 임상적 변화를 알아보고 부갑상선 절제술의 의미를 재고 해보고자 하였다. 방법: 1996년부터 2009년까지 총 126명이 서울대학교 병원에서 부갑상선 절제술을 시행 받았으며 각각 일차성 96명, 이차성 24명, 삼차성 6명이었다. 환자들의 나이, 성별, 생화학적 검사, 수술방법, 병리학적 검사 결과를 전자 의무기록을 통해 후향적으로 분석하였다. 결과: 모든 세 군의 환자에서 혈청 칼슘, 부갑상선 호르몬, 이온화 칼슘이 수술 전보다 호전을 보였다. 이차성 환자군은 다른 두 군에 비해 수술 전, 후의 부갑상선 호르몬이 높았으며(p<0.001, p=0.036), 수술 후 지속적인 부갑상선 기능 항진증(30.4%) 및 일과성 저칼슘혈증(87.5%)도 다른 두 군에 비해 많이 발생하였다.(p< 0.001) 일과성 저칼슘혈증의 대부분(90.4%) 은 6개월 이내 회복 되었다. 이차성 환자에서 부갑상선 아전 및 전 절제술을 시행 받은 경우 수술 후 일과성 저칼슘혈증이 많이 나타났으나(71.4%), 제한적 절제술을 시행 받은 경우 지속적 부갑상선 기능항진증이 더 많이 나타났다.(50%) 결론: 부갑상선 절제술은 생화학 검사상의 호전을 위한 치료 방법으로 추천될 수 있으며, 이차성에서는 제한적 절제를 하는 경우 지속적 부갑상선 항진증의 빈도가 더 높으므로 부갑상선 아전 및 전 절제술을 시행해야 한다. Purpose: Primary hyperparathyroidism(PHPT), secondary hyperparathyroidism(SHPT) and tertiary hyperparathyroidism(THPT) are different in the cause, treatment and prognosis. However the parathyroidectomy has been an efficient treatment in all hyperparathyroidism groups. A single institution`s 14 year experience of surgical treatment was analyzed to investigate perioperative changes of clinical characteristics and reconsider the value of parathyroidectomy as the treatment option. Materials and Methods: From 1996 to 2009, 126 patients underwent parathyroidectomy at single institute and the number of patients with PHPT, SHPT and THPT were 96, 24 and 6 retrospectively. The electronic medical records of age, sex, biochemical analysis, operative method, and pathologic results were reviewed retrospectively. Results: Postoperative calcium (Ca), parathyroid hormone (PTH), ionized calcium (iCa) levels were improved definitely than preoperative Ca, PTH, iCa level in all three groups. Pre and postoperative PTH level in SHPT was higher than in PHPT and THPT(p<0.001, p=0.036) and postoperative persistent PTH increased status were more common in SHPT.(30.4%, p<0.001) Postoperative temporary hypocalcemia was more common in SHPT(87.5%, p<0.001), almost of them (90.4%) were recovered in 6 month. In SHPT group, temporary hypocalcemia were more common in subtotal or total parathyroidectomy group than in limited resection group (94.1%) but persistent iPTH increase were more common in limited resection group (50%). . Conclusion: Parathyroidectomy is highly recommended to improve biochemical laboratory findings in patients with hyperparathyroidism. And in SHPT, subtotal or total parathyroidectomy is more appropriate surgical method for reducing the high incidence of persistent hyperparathyroidism.

Brown Tumor of the Cervical Spines: A Case Report with Literature Review

Mohammad Dursi Alfawareh,Mohammed Mohamoud Halawani,Walid Ismail Attia,Mohamoud Halawani 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.1

To report a rare case of axis brown tumor and to review literature of cervical spine brown tumor. Brown tumor is a rare bone lesion, incidence less than 5% in primary hyperparathyroidism. It is more common in secondary hyperparathyroidism with up to 13% of cases. Brown tumor reactive lesion forms as a result of disturbed bone remodeling due to long standing increase in parathyroid hormones. Cervical spine involvement is extremely rare, can be confused with serous spine lesions. To date, only four cases of cervical spine involvement have been reported. Three were due to secondary hyperparathyroidism. Only one was reported to involve the axis and was due to secondary hyperparathyroidism. This is the first reported case of axis brown tumor due to primary hyperparathyroidism. A case report of brown tumor is presented. A literature review was conducted by a Medline search of reported cases of brown tumor, key words: brown tumor, osteoclastoma and cervical lesions. The resulting papers were reviewed and cervical spine cases were listed then classified according to the level, cause, and management. Only four previous cases involved the cervical spine. Three were caused by secondary hyperparathyroidism and one was by primary hyperparathyroidism which involved the C6. Our case was the first case of C2 involvement of primary hyperparathyroidism and it was managed conservatively. Brown tumor, a rare spinal tumor that presents with high PTH and giant cells, requires a high level of suspicion.

Normocalcemic Primary Hyperparathyroidism: Need for a Standardized Clinical Approach

Guido Zavatta,Bart L. Clarke 대한내분비학회 2021 Endocrinology and metabolism Vol.36 No.3

Since normocalcemic primary hyperparathyroidism (NHPT) was first defined at the Third International Workshop on the Management of Asymptomatic Primary Hyperparathyroidism in 2008, many papers have been published describing its prevalence and possible complications. Guidelines for the management of this condition are still lacking, and making the diagnosis requires fulfillment of strict criteria. Recent studies have shown that intermittent oscillations of serum calcium just below and slightly above the normal limits are very frequent, therefore challenging the assumption that serum calcium must be consistently normal to make the diagnosis. There is debate if these variations in serum calcium outside the normal range should be included under the rubric of NHPT or, rather, a milder form of classical primary hyperparathyroidism. Innovative approaches to define NHPT have been proposed that still need to be validated in prospective studies. Non-classical complications, especially cardiovascular complications, have been associated with NHPT, indicating that hyperparathyroidism may be a cardiovascular risk factor. New associations between parathyroid hormone (PTH) and several other comorbidities have also been reported from observational studies, suggesting that excessive PTH secretion might cause tissue dysfunction independent of serum calcium. Heterogeneous studies using different definitions of NHPT, however, make it difficult to draw definitive conclusions regarding the role of PTH excess when complications other than osteoporosis or kidney stones are described. This review will focus on clinical aspects and suggest an approach to NHPT.
