This book provides a visual demonstration of normal and ectopic locations of parathyroid adenomas using different modalities in patients with PHPT and to describe parathyroid gland–related pathology. It includes several modern imaging modalities for localization of parathyroid glands and parathyroid adenomas, such as Sestamibi scan, SPECT/CT Sestamibi scan, neck ultrasound, MRI, thin-cut CT, and 4D CT scans. Written by experts in the field, chapters include pathology images corresponding to radiology imaging for some presented cases (gross and high-power view). Authors have also collected radiological images of difficult-to-localize parathyroid adenomas in ectopic (abnormal) locations. The atlas is organized by location of the adenomas in upper and lower eutopic locations followed by ectopic locations. Each case demonstrates dual or triple modalities such as US, Sestamibi scan, or SPECT/CT Sestamibi scan, thin-cut CT scan, or 4D CT performed on the same patient. A chapter on parathyroid pathology is also included to help the reader understand challenges in pathological interpretation. Atlas of Parathyroid Imaging and Pathology serves as a valuable reference for radiologists, endocrine surgeons, head and neck surgeons, ENT surgeons, surgical oncologists, endocrinologists, pathologists, nephrologists, students, and all physicians and allayed health practitioners involved in the treatment of patients with primary, secondary, and tertiary hyperparathyroidism.
