Parathyroid Cyst as a Cervical or Cervicomediastinal Mass
Surgical Division, Institute of Clinical Medicine, University of Tsukuba lbaraki, Japan
*Second Department of Surgery, University of Tokyo Tokyo, Japan
Received November 17, 1977; Three cases of parathyroid cyst are reported. The cysts were invariably located in the lower neck and presented a typical cystic pattern on ultrasound scanning. A thin-needle aspiration of the cyst readily yielded transparent, watery fluid containing a high titer of immunoreactive parathyroid hormone (PTH). These findings confirmed the diagnosis of parathyroid cyst. At the time of operation, thickening of the cyst wall and adhesion to the surrounding structures were found. These unusual findings were thought to be induced by previous punctures. In one case, there was a large cyst extending into the mediastinum and causing partial respiratory obstructiona condition requiring prompt surgical removal of the cyst.
