Primary hyperparathyroidism, a machine learning approach to identify multiglandular disease in patients with a single adenoma found at preoperative Sestamibi-SPECT/CT.

Eur J Endocrinol 2022 Jun 1. Epub 2022 Jun 1.

A Sanchez-Crespo, Department of Medical Radiation Physics and Nuclear Medicine, Karolinska University Hospital, Stockholm, 171 76, Sweden.

Preoperative Imaging with [F]-Fluorocholine PET/CT in Primary Hyperparathyroidism.

J Clin Med 2022 May 23;11(10). Epub 2022 May 23.

Department of Nuclear Medicine, University Hospital, LMU Munich, 81377 Munich, Germany.

Primary hyperparathyroidism (pHPT) is a common endocrine disorder due to hyperfunctioning parathyroid glands. To date, the only curing therapy is surgical removal of the dysfunctional gland, making correct detection and localization crucial in order to perform a minimally invasive parathyroidectomy. F-Fluorocholine positron emission tomography/computed tomography (F-FCH PET/CT) has shown promising results for the detection of pHPT, suggesting superiority over conventional imaging with ultrasounds or scintigraphy.

Ear Nose Throat J 2022 May 21:1455613221103082. Epub 2022 May 21.

Department of General Surgery (Thyroid Surgery), 556508The Affiliated Hospital of Southwest Medical University, Luzhou, China.

The occurrence of ectopic intrathyroidal parathyroid adenoma (EPTA) is very rare, which causes some difficulties in diagnosis and complicates treatment. In addition, the occurrence of EPTA with nodular goiter (NG) is rare, which makes diagnosis difficult and requires the assistance of clinical evidence, imaging data, and cytological examination results. Therefore, we present a patient with a final diagnosis of ETPA with NG. Read More

Parathyroid Computed Tomography: Pearls, Pitfalls, and Our Approach.

Neuroimaging Clin N Am 2022 May;32(2):413-431

Department of Radiology, Wake Forest School of Medicine, Medical Center Boulevard, Winston Salem, NC 27157, USA.

Parathyroid imaging is predominantly used for preoperative localization of parathyroid lesions in patients with the biochemical diagnosis of primary hyperparathyroidism. Although imaging algorithms vary, in the era of minimally invasive parathyroidectomy for single parathyroid adenomas, multiphase parathyroid computed tomography (CT) (4-dimensional CT) has emerged as a favored modality for presurgical mapping of parathyroid lesions. Implementation and correct interpretation of these studies can be challenging, although confidence and accuracy improve with experience and volume. Read More

Department of Internal Medicine, Endocrine Research Institute, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea.

Preoperative localisation studies are essential for parathyroidectomy in patients with primary hyperparathyroidism. If the location of abnormal parathyroid glands cannot be identified through non-invasive studies, parathyroid venous sampling (PVS) may be employed. In this study, we evaluated the utility of preoperative PVS in parathyroid surgery. Read More

Service de Chirurgie Endocrinienne, Centre Hospitalier Lyon Sud, Hospices Civils de Lyon, 69495 Pierre-Bénite, France.

This large, retrospective, single-centre study evaluated the diagnostic performance of F-choline positron emission tomography/contrast-enhanced computed tomography (PET/ceCT) in preoperative parathyroid adenoma detection in primary hyperparathyroidism cases after negative/inconclusive ultrasound or other imaging findings. We included patients who underwent surgery and F-choline PET/ceCT for inconclusive imaging results between 2015 and 2020. We compared the F-choline PET/ceCT results with surgical and histopathological findings and identified the variables influencing the correlation between F-choline PET/ceCT and surgical findings.

The Diagnostic Value of Contrast Enhanced Ultrasound for Localization of Parathyroid Lesions in Primary Hyperparathyroidism: Comparison With Color Doppler Ultrasound: Comparison With Color Doppler Ultrasound.

J Ultrasound Med 2022 Mar 31. Epub 2022 Mar 31.

Department of Otolaryngology Head and Neck Surgery, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

Objectives: Preoperative localization of pathological parathyroid glands with imaging is essential for focused unilateral neck exploration and minimally invasive techniques. Recently published studies suggested that contrast enhanced ultrasonography (CEUS) had high accuracy in the localization of hyperfunctioning parathyroid glands, with a general increase in the sensitivity as compared to conventional sonography. The purpose of this study was to determine the usefulness of CEUS in the localization of parathyroid lesions relating to surgical and histopathological data, in comparison to color Doppler ultrasound (CDUS), in the same series of patients.
