Parathyroid adenoma sometimes present in ectopic location and may pose a difficulty in both diagnosis and localization. We report a case of a young lady suspected to have neuroendocrine tumor of the mediastinum demonstrating synaptophysin positivity on an initial core needle biopsy. Ga-68 DOTANOC positron emission tomography-computed tomography revealed a somatostatin receptor-expressing lesion in the anterior mediastinum with tracer avid multiple lytic bone lesions. On further biochemical and imaging workup with Tc-99 m SESTAMIBI, a diagnosis of ectopic parathyroid adenoma was made which was further confirmed with surgical excision.

Adolescent primary hyperparathyroidism (PHPT) is a rare endocrine disorder bearing distinctions from the adult form. This review examines its unique aspects, focusing on clinical presentation, genetic etiologies, genotype-phenotype correlations, and therapeutic management. Adolescent PHPT often has a genetic basis, whether familial, syndromic, or apparently sporadic, and identifying the underlying genetic cause is important for patient care.

Fever of unknown origin (FUO) can be a common manifestation of multiple disease processes like infections, hematological & solid organ malignancies, autoimmune disorders, and autoinflammatory diseases. Endocrine causes of FUO are rare but should be considered in differential diagnosis. We present a case of a 35-year-old female with prolonged on-and-off fever and intermittent vomiting for nine months, where extensive workups for chronic infections, malignancy, and autoimmune conditions initially yielded no definitive diagnosis.

Background: Primary hyperparathyroidism (pHPT) is the third most common endocrine disease, affecting predominantly postmenopausal women. About 85% of cases are caused by a solitary parathyroid adenoma which leads to a hypersecretion of the parathyroid hormone (PTH) and consequently to elevated serum calcium concentrations. Parathyroidectomy is the only curative treatment.

The standardization of preoperative imaging in primary hyperparathyroidism is one of the current challenges of endocrine surgery. A correct localization of the hypersecretory gland by neck ultrasound and 99mTc-sestamibi (MIBI) scintigraphy are not sufficiently sensitive in some cases. In recent years, CT-4D, 18F-Fluorocholine PET/CT, and radio-guided parathyroidectomy have come into common use.

Persistent primary hyperparathyroidism is defined as the persistence or recurrence of hypercalcemia within 6 months of parathyroid surgery. Recurrent primary hyperparathyroidism is defined as the recurrence of primary hyperparathyroidism more than 6 months after an initially curative parathyroidectomy. In these situations, it is essential to rule out differential diagnoses, and in particular secondary hyperparathyroidism and familial hypocalciuric hypercalcemia.
