A 57 year old female patient was diagnosed as primary hyperparathyroidism after incidental finding of hypercalcemia. She was treated with radioiodine for Graves disease twenty years ago. Preoperative localization procedures with sonography and CT were unrevealing but 201 thallium scintiscan clearly demonstrated ectopic parathyroid adenoma which was confirmed by surgery. Brief review of the preoperative parathyroid localization procedure was done and the relationship between radioiodine therapy and hyperparathyroidism was discussed.

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.

Objective: To evaluate the safety, feasibility, and efficacy of microwave ablation (MWA) for the treatment of primary hyperparathyroidism (PHPT). Materials and Methods: This study enrolled 67 PHPT patients (22 men, 45 women; mean age, 56.0 ± 16.3 years; range, 18-83 years) from January 2015 to December 2018. The laboratory data, including the serum intact parathyroid hormone (iPTH), calcium, phosphorus, and alkaline phosphatase (ALP) levels, were evaluated before MWA and again 2 hours, 1 day, 7 days, 1 month, 3 months, 6 months, 12 months, 18 months, and 24 months after. Results: Complete ablation was achieved with all 72 hyperplastic parathyroid glands found on the 67 patients enrolled, 64 of whom were treated in one session and 3 were treated over two sessions. The technical success rate was 100%. The median follow-up time was 13.6 months (range, 10.0-31.1 months). The clinical success rate was 89.4%. The volume reduction rate was 79.4% at 6 months. Compared to pre-MWA, the serum iPTH, calcium, phosphorus, and ALP levels had significantly improved 6 months post-MWA (iPTH, 157.3 pg/mL vs. 39.2 pg/mL; calcium, 2.75 ± 0.25 mmol/L vs. 2.34 ± 0.15 mmol/L; phosphorus, 0.86 ± 0.20 mmol/L vs. 1.12 ± 0.22 mmol/L; ALP, 79 U/L vs. 54 U/L, respectively; all, p < 0.01). Hoarseness was a major complication in 4 patients (6.0%), but it improved spontaneously within 2-3 months. Conclusion: MWA is safe, feasible, and effective for the treatment of PHPT.

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.

Mucolipidosis II (ML II) or inclusion cell disease (I-cell disease) is a rarely occurring autosomal recessive lysosomal enzyme-targeting disease. This disease is usually found to occur in individuals aged between 6 and 12 months, with a clinical phenotype resembling that of Hurler syndrome and radiological findings resembling those of dysostosis multiplex. However, we encountered a rare case of an infant with ML II who presented with prenatal skeletal dysplasia and typical clinical features of severe secondary hyperparathyroidism at birth. A female infant was born at $37^{+1}$ weeks of gestation with a birth weight of 1,690 g (<3rd percentile). Prenatal ultrasonographic findings revealed intrauterine growth retardation and skeletal dysplasia. At birth, the patient had characteristic features of ML II, and skeletal radiographs revealed dysostosis multiplex, similar to rickets. In addition, the patient had high levels of alkaline phosphatase and parathyroid hormone, consistent with severe secondary neonatal hyperparathyroidism. The activities of ${\beta}$-D-hexosaminidase and ${\alpha}$-N-acetylglucosaminidase were moderately decreased in the leukocytes but were 5- to 10-fold higher in the plasma. Examination of a placental biopsy specimen showed foamy vacuolar changes in trophoblasts and syncytiotrophoblasts. The diagnosis of ML II was confirmed via GNPTAB genetic testing, which revealed compound heterozygosity of c.3091C>T (p.Arg1031X) and c.3456_3459dupCAAC (p.Ile1154GlnfsX3), the latter being a novel mutation. The infant was treated with vitamin D supplements but expired because of asphyxia at the age of 2 months.

Milk-alkali syndrome (MAS), a triad of hypercalcemia, metabolic alkalosis, and renal failure, is associated with ingestion of large amounts of calcium and absorbable alkali. MAS is the third most common cause of hypercalcemia in hospital, after primary hyperparathyroidism and malignant neoplasm. MAS is not often reported in the Korean literature. We describe MAS secondary to intake of calcium citrate for the treatment of osteoporosis with thoracic spine compression fracture. A 70-year-old man presented to our hospital with a 1-week history of general weakness and lethargy. He was found with acute kidney injury (serum creatinine, 4.6 mg/dL), hypercalcemia (total calcium, 14.8 mg/dL), and alkalosis. Laboratory evaluation excluded both hyperparathyroidism and malignancy. Mental status and serum calcium level was normalized within a week after proper hydration and intravenous administration of furosemide. However, he developed aspiration pneumonia, pseudomembranous colitis, and sepsis with multi-organ failure. Despite intensive treatment including inotropics, mechanical ventilation, and renal replacement therapy, he expired with no signs of renal recovery on the 28th hospital day.

섬유성 골이형성증은 비정상적인 섬유성 골조직으로 대체되며 느리게 진행하는 골병변이다. 섬유성 골이형성증과 부갑상선기능항진증은 흔하게 관찰되는 질환이나 McCune-Albright 증후군 없이 일차성 부갑상선기능항진증에 동반된 섬유성 골 이형성증은 거의 보고된바가 없다. Tc-99m MDP 골스캔이 섬유성 골이형성증의 진단에 유용하다고 알려져 있으나, Tc-99m MIBI 영상은 아직 보고된 바가 없다. 저자들은 McCune-Albright 증후군이 없이 부갑상선기능항진증에 동반된 섬유성 골 이형성증의 Tc-99m MIBI 스캔과 Tc-99m MDP 골스캔의 영상을 비교하였다. Tc-99m MDP 골스캔상 병변 부위에서 증가된 섭취 소견을 보였으며, Tc-99m MIBI 조기영상에서도 동일한 위치에서 섭취증가가 관찰되었다. 2시간 지연 Tc-99m MIBI 영상에서는 Tc-99m MIBI의 섭취가 배출되는 소견을 보였다. 섬유성 골이형성증 병변에서 Tc-99m MIBI 스캔이 유용할 것이라고 생각하며, 섬유성 골이형성증 병변에서 Tc-99m MIBI의 섭취를 증가시키는 인자에 대한 더 많은 연구가 필요할 것으로 생각한다.

부갑상선암은 매우 드문 내분비악성 종양으로 부갑상선기능 항진증의 0.5~4%를 차지하며 흔히 고칼슘 혈증과 부갑상선호르몬의 증가를 보인다. 비기능성 부갑상선암은 부갑상선기능 항진증으로 나타나는 증상이 없으며 병리조직학적 진단기준이 분명하지 않아 늦게 진단이 되는 질환이다. 근치적 절제술이 가장 표준적인 치료이지만 수술 후 국소재발이 흔하기 때문에 불완전 절제가 시행되었거나 미세 잔류 종양이 있는 경우 외부 방사선치료를 시행하여 국소 조절률 향상을 얻을 수 있다고 보고되고 있다. 저자는 부갑상선에 발생한 비기능성 악성종양으로 근치적 절제술 후 외부 방사선치료를 시행한 1예를 경험하였기에 문헌 고찰과 함께 이를 보고하고자 한다.
