ABSTRACT
Parathyroid carcinoma (PTC) is a rare endocrine tumor and uncommon cause for primary hyperparathyroidism. 18F-fluorocholine (FCH) positron emission tomography and computed tomography (PET/CT) has shown promising results in the detection of parathyroid adenoma, though its role in PTC is undefined due to the paucity of incidence. The authors in this case report discuss the possible complimentary role of FCH PET/CT with 18F-fluorodeoxyglucose PET/CT in the evaluation of the management of suspected recurrence, since this rare entity has high loco-regional and distant recurrence of the disease.
ABSTRACT
18F-Fluorocholine (FCH) PET/CT is evolving as a functional imaging modality for the preoperative imaging of abnormal parathyroid tissue(s) helping to localize eutopic and ectopic parathyroid tissue and limit the extent of surgery. FCH PET/CT may show incidental uptake in various thyroid lesions necessitating further evaluation, whereas the role of 18F-fluorodeoxyglucose (FDG) PET/CT in the detection of incidental thyroid nodules is well documented. The case of a middle-aged woman with dual pathology of parathyroid adenoma and papillary thyroid cancer detected on FCH and FDG PET/CT is presented.

ABSTRACT
Technetium-99m sestamibi myocardial perfusion imaging is commonly employed non-invasive study for evaluation of coronary artery disease; however, incidental extracardiac scintigraphic findings observed may provide additional diagnostic information. The authors present the unusual scintigraphic findings in a case of decompensated liver disease with right hepatic hydrothorax, being planned for orthotopic liver transplant.

Primary hyperparathyroidism is caused by parathyroid adenoma in the majority of cases and diagnosis is usually made biochemically. Pre-surgical localization of parathyroid adenoma is essential to limit the extent of surgery and avoid missing them at ectopic sites. Anatomical and functional imaging are used for the localization, but may fail to identify the small and ectopic parathyroid adenoma. We present a case of small sized ectopic parathyroid adenoma at unusual location detected by F-18 fluorocholine (FCH) PET/CT, where other imaging modalities failed. The post-operative histopathology confirmed the diagnosis of ectopic parathyroid adenoma.
