[Mediastinal parathyroid adenomas on a 5th ectopic gland. 2 case reports]. / Les adénomes parathyroïdiens médiastinaux sur 5ème glande ectopique. Deux observations.

ABSTRACT

Mediastinal parathyroid adenoma located on the 5th ectopic gland is rare. We report here two new cases diagnosed by scintigraphy. In one case the adenoma was found to be located in the mediastinum prior to cervicotomy. The modern imaging methods capable of locating parathyroid adenomas are evaluated.
