Giant hyperplastic parathyroid gland in the mediastinum--partially cystic and calcified.
A large, calcified paratracheal mass was identified in a patient with secondary hyperparathyroidism. The mass proved to be a giant, calcified, cystic, hyperplastic parathyroid gland. Radiographic and ultrasonic imaging techniques were quite useful in diagnostic evaluation. Whenever a calcified mediastinal or neck mass is discovered, especially in a patient with hyperparathyroidism, parathyroid enlargement should be a diagnostic consideration.
