MIBI Scintigraphy for the Detection of Ectopic Parathyroid Tumor

Abstract

We treated an ectopic parathyroid tumor which had not been detected by several tests, but was detected by MIBI scintigraphy. The patient was a 34-year-old woman. In December 1987, she was diagnosed as having left renal calculus and primary hyperparathyroidism. Exploration of her cervical region was performed at our urological section. Post-operative pathosis for the former section was normal, but progress after operation had kept showing higher value on Ca. In March 1996, MIBI scintigraphy was performed. Intussusception was found in the right submaxillary region, and she was therefore readmitted for enucleation of an ectopic parathyroid tumor on January 20, 1997. The ectopic parathyroid tumor was present between the right common carotid artery and the right internal carotid artery, and the histological examination revealed parathyroid hyperplasia.
