Radiographic findings in recurrent parathyroid carcinoma.
Seven cases of recurrent parathyroid carcinoma were reviewed. Subperiosteal resorption was seen in 6, pulmonary nodules in 4, renal calculi in 5, brown tumors in 5, and pancreatic calcification in 1. Angiography was performed in 5 patients, showing 1 definite and 2 probable cervical recurrences, 1 mediastinal lesion, and 1 case of possible bone metastases. Venous sampling for parathyroid hormone was carried out in 4 patients and suggested residual disease in 2; in addition, there were 1 false and 1 true negative. CT was performed in 4 patients and was useful in delineating metastatic pulmonary nodules, cervical recurrence, and hepatic metastases. The radiographic approach to recurrent parathyroid carcinoma and the use of CT and angiography are discussed.
