    (1997) Mosso, L; Lopez, JM; Trincado, P; Olea, E; Talesnik, E; Verdugo, C
    We report two women presenting with parathyroid cysts. A 20 years old woman presented with goiter and a cystic lesion in the left thyroid lobe was identified on ultrasound examination and CAT scan. The patient had hypercalcemia and elevated PTH levels. The content of the cyst, obtained by needle aspiration, had an extremely high PTH concentration. The patient was operated, removing the cyst and a remaining thymus. Pathological study confirmed the diagnosis of a parathyroid cyst. An 11 years old girl presented with a mass in the left thyroid lobe. An ultrasound examination disclosed the presence of a cystic nodule. The patient was otherwise asymptomatic and laboratory work up was normal. The patient was operated and pathological examination of the surgical piece revealed a parathyroid cyst.
