- Favor Atypical Parathyroid Adenoma with Cystic Degeneration and Prior Rupture
Submitted by: Dr. Jennifer Hunt
A 75 year old woman presented with a neck mass and swallowing symptoms. She was found to be mildly hypercalcemic and a sestamibi scan identified an enlarged parathyroid gland located next to the esopagus. Intra-operatively the surgeon reported that the gland was very difficult to remove because it was extensively adherent to the esophagus and the vertebral fascia. An en bloc resection was performed with clean margins.
