[CT for diagnosis of parathyroid adenoma].

We analyzed Ct findings of 10 cases with parathyroid adenoma which had been verified by surgery and pathologic section. The correct localization of 9 adenomas was made by CT preoperatively. The method of CT scanning of parathyroid adenoma were elucidated. The results showed that most adenomas were located in the groove between trachea and esophagus. The contour of tumors was oval, the edge was smooth and regular. Enhancement CT images were helpful for differentiating the tumor from blood vessel. It is indicated that CT scanning is a good method for localizing the parathyroid adenoma.
