parathyroid adenomas, or hyperplasia may be present in patients with hypercalcemia. treatment is by surgical excision, but about 10% of the lesions may be in ectopic locations. pre-operative localization of the lesions with non-lvasive imaging, using radionuclides, ultrasound, ct, or mr], may simplify surgery, and reduce patient morbidity. however, the reports of the accuracy of the currently a...

Objective(s): In this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (SPECT/CT) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. Methods: Five patients with primary hyperparathyroidism (PHPT) and 4 patients with secondary hyperparathyroidism (SHPT) we...

Parathyroid carcinoma is very rare, with only a few documented cases. Hence, metastatic lesions are infrequently documented on scintigraphic imaging. We present a case of a 63-year-old female presenting with elevated serum levels of ionized calcium and parathyroid hormone (PTH) who was referred to our department for a parathyroid scan with SPECT/ CT. Parathyroid scintigraphy showed a focus of i...

Primary hyperparathyroidism (pHPT) is defined by the excess level of parathyroid hormone (PTH). Parathyroid adenoma is responsible for about 80% of all pHPT. Parathyroid adenoma with cystic feature and atypical pathology is recognized as a rare entity. Technetium-99m methoxy isobutyl isonitrile ([99mTc]Tc-MIBI) scintigraphy has favorable detection rate for ectopic gland as well as th...

abstract men-i is a rare genetic disorder classically characterized by a predisposition to tumors of the parathyroid glands, anterior pituitary gland, and pancreatic islet cells. we present a case of men-i syndrome diagnosed using predominantly nuclear medicine imaging followed by radionuclide therapy, thus emphasizing the role of nuclear imaging in diagnosing and treating men-i.

Several imaging modalities exist for the detection of parathyroid adenomas in patients with primary hyperparathyroidism. Unlike solitary parathyroid adenoma, parathyroid hyperplasia in patients with secondary hyperparathyroidism hitherto is difficult to assess with any imaging modality. Our case of a young patient with chronic kidney failure illustrates that F-fluorocholine PET/MR might be an i...

BACKGROUND Intraoperative identification of parathyroid adenomas can be challenging. We hypothesized that low-doses methylene blue (MB) and near-infrared fluorescence (NIRF) imaging could be used to identify parathyroid adenomas intraoperatively. METHODS MB was injected intravenously after exploration at a dose of 0.5 mg/kg into 12 patients who underwent parathyroid surgery. NIRF imaging was ...
