[Parathyroid cyst associated with acute respiratory failure and jugular vein thrombosis].

Parathyroid cysts are much less common than other cystic lesions of the neck. The great majority of parathyroid cysts are endocrine non-functioning. Parathyroid cysts may become symptomatic because of hormonal activity or due to the size and pressure effects. This is a case history of a 43 year-old woman, who presented with dyspnea. A 9 + 8 + 6cm cervical-mediastinal parathyroid cyst causing dyspnea, dysphagia, respiratory failure and jugular vein thrombosis was found.
