Video-assisted mediastinoscopy (VAM) for surgical resection of ectopic parathyroid adenoma
Journal of Cardiothoracic Surgery, 2007
Background: Ectopic mediastinal parathyroid adenomas or hyperplasia account for up to 25% of primary hyperparathyroidism (HPT). Two percent of them are not accessible by standard cervical surgical approaches. Surgical resection has traditionally been performed via median sternotomy or thoracotomy and more recently, via video assisted thoracoscopic surgery (VATS). We present our experience with the novel use of Video-Assisted Mediastinoscopy (VAM) for resection of ectopic mediastinal parathyroid glands.
Localization and management of mediastinal parathyroid adenoma – a case report
IMC journal of medical science, 2022
Ectopic parathyroid adenoma sometimes poses diagnostic challenge and can be a cause of persistent and recurrent primary hyperparathyroidism. Anterior mediastinum is one of the locations for ectopic parathyroid adenoma. Surgical excision is the only cure and for successful surgery, pre-operative localization is crucial. Chance of failed surgery is being increased without prior localization of the ectopic gland. The combination of single photon emission computed tomography (SPECT) and computed tomography (CT) has got high sensitivity for accurate localization of ectopic parathyroid. On the other hand, with accurate localization surgical outcome is excellent. Here we report, successful localization and management of a case of primary hyperparathyroidism due to adenoma in anterior mediastinum in 47-year-old man.
Case Report Mediastinal Parathyroid Adenoma
2015
An ectopically placed parathyroid adenoma in the anterior mediastinum is a rare cause of persistent or recur-rent primary hyperparathyroidism (PHPT) and is recog-nized as an important cause of failed primary neck explo-ration. We encountered 3 such cases amongst 70 surgically treated patients with PHPT (4.3%) over a 20-year period. In 2 cases, the offending adenoma could be removed at first exploration whereas in the 3rd case, it was successfully removed with mediastinal exploration after 2 failed neck explorations. In established cases of PHPT with equivocal preoperative localization studies or negative neck explo-rations, an ectopically placed parathyroid adenoma should be considered and once localized, should be surgically removed for cure.
Thoracoscopic removal of a posterior mediastinal parathyroid adenoma
Journal of Clinical Images and Medical Case Reports
Ectopic Parathyroid Adenomas (EPA) can occur in many anatomical locations and the most frequent one was the mediastinum region. Traditionally, the adenoma resection has been performed through conventional thoracotomy or sternotomy. Recently, a few cases of thoracoscopic excision of mediastinal adenoma were reported. We report here the case of a successful exclusive thoracoscopic removal of a mediastinal parathyroid adenoma. A 58-year-old female patient presented with bilateral renal stones and fatigue. Biology results showed elevated serum calcium and parathyroid hormone levels. The diagnosis of primary hyperparathyroidism caused by solitary EPA in lateralesophageal region was confirmed by imaging tools. The patient underwent successful thoracoscopic resection. He was discharged on the 2rd postoperative day. Keywords: primary hyperparathyroidism; parathyroid adenoma; mediastinum; thoracoscopic excision.
The results of surgery for mediastinal parathyroid tumors: a comparative study of 63 patients
Langenbeck's Archives of Surgery, 2010
Purpose Parathyroidectomy for ectopic mediastinal hyperfunctioning glands could be performed by transcervical approach, sternotomy, thoracotomy, and recently by thoracoscopic and mediastinoscopic approaches. This study was aimed to analyze the results of traditional and videoassisted parathyroidectomy for mediastinal benign hyperfunctioning glands. Methods Fifty-one upper mediastinal exploration by a conventional cervicotomy, 12 by video-assisted approaches (two thoracoscopy and 10 transcervical mediastinoscopy) and six by sternotomy were performed in 63 patients with primary hyperparathyroidism. Results Video-assisted and sternotomic parathyroid explorations achieved biochemical cure in all cases; following conventional transcervical mediastinal exploration, a persistent hyperparathyroidism occurred in 11.8% of patients, who were subsequently cured by sternotomic approach. No complications occurred after video-assisted parathyroidectomy, while an overall morbidity rate of 50% and 10% was found after sternotomic and conventional cervicotomic approaches. Postoperative pain and hospital stay were significantly increased following sternotomy; patient's subjective cosmetic satisfaction was significantly higher after video-assisted and conventional cervicotomic approaches.

INTRODUCTION: The most common cause of chronic hypercalcemia is primary hyperparathyroidism (PHPT). However, owing to the diverse presentation of hypercalcemia, the diagnosis often goes unnoticed culminating as a continuum of recurrence of symptoms. Nephrolithiasis, decreased bone mineral density and peptic ulcer disease are the main clinical sequelae. Among the causes of PHPT 80% are caused by parathyroid adenomas (PA). However, only rarely, these adenomas are found ectopically. PRESENTATION OF CASE: We present the case of a 66-year-old female with a history of recurrent renal stones and peptic ulcer disease. She was found to have elevated serum calcium and PTH levels. However, subsequent high resolution CT scan of chest and neck failed to demonstrate any abnormality. Therefore, an anterior planar Technetium-99m-sestamibi (MIBI) scintigraphy scan using a single-tracer was done and it identified ectopic anterior mediastinal parathyroid adenoma. The patient was successfully managed with video-assisted thoracoscopic surgery and excision of the mass with follow up calcium level monitoring. DISSCUSSION: An elevated calcium level should prompt a thorough workup, as sometimes it's the only clue to the unrelated and diversified systemic manifestations of hypercalcemia. Hyperparathyroidism due to ectopic adenoma is quite rare and possess a diagnostic and management challenge. CONCLUSION: Symptomatic hypercalcemia and high level of PTH without local PA should alert physicians to search for ectopic locations through imaging. VATS is a safe and effective minimally invasive procedure for the resection of ectopic mediastinal PA and it should be considered as the first line approach for resection of these ectopic tumors.

Paratiroid adenomları primer hiperparatiroidizmin en sık nedenidir. Bu yazıda yorgunluk, hiperkalsemi ve hiperparatiroidisi olan 44 yaşında bir erkek hasta sunuldu. Paratiroid sintigrafisi ve torasik bilgisayarlı tomografisinde, ektopik olarak ön mediastende yerleşim gösteren paratiroid adenomu ile uyumlu bir lezyon görüldü. Paratiroid adenomu ameliyat sırası gama prob kılavuzluğunda başarı ile eksize edildi. Paratiroid adenomlarının yerleşiminin ameliyat öncesinde belirlenmesi gereklidir. Bu nedenle; ultrasonografi, paratiroid sintigrafisi ve paratiroid sintigrafisi pozitif olan hastalarda ameliyat sırasında yapılan gama prob kılavuzluğu tanı ve cerrahi tedavinin başarısı için çok önemlidir.

Percutaneous Transsternal Cryoablation of Ectopic Parathyroid Adenoma in the Anterior Mediastinum
Journal of the Endocrine Society, 2017
Ectopic parathyroid adenomas are common in the context of hyperparathyroidism and represent a unique challenge in terms of localization and treatment. Often they are related to higher serum calcium levels than those associated with parathyroid adenomas in typical locations. Additionally, ectopic adenomas often lead to higher morbidity due to failed parathyroid exploration and multiple attempts at surgical removal. We present two cases of computed tomography-guided percutaneous transsternal cryoablation of ectopic parathyroid adenomas in the anterior mediastinum, one after failed surgical resection and the other after failed transarterial embolization. Cryoablation may represent a safe and effective alternative to surgery or embolization and should be included in the therapeutic algorithm in patients with percutaneously accessible lesions.
