Abstract
Since 1994, there have been 10 cases (1 male, 9 females, 37-72 years old) of primary hyperparathyroidism at our hospital. CT, ultrasonography (US), and MIBI scintigraphy (MIBI) were undertaken for preoperative imaging of the parathyroid tumor. In 9 adenoma cases, accurate localization was obtained in 6 of 9 cases for US, in 8 of 8 cases for CT, and in 9 of 9 cases for MIBI. After the surgery, laboratory data of Ca and i-PTH were in the normal range. Histopathological diagnosis showed 9 adenoma cases and 1 hyperplasia case. Three cases were associated with thyroid diseases.
This paper presents two cases with rare clinical symptoms. The chief complaint of the first case was hoarseness. Transient recurrent nerve palsy was observed two times in 2 years. During the surgery, the tumor existed just behind the right recurrent nerve. By histological examination, the tumor was diagnosed as parathyroid adenoma. There has been no recurrent nerve palsy since the surgery. The second case had been treated after diagnosis of deglusion for 3 years in a psychiatry clinic. CT and MIBI showed parathyroid tumor just below the right lobe of the thyroid. After surgery, psychological symptoms were dramatically improved.
