Clinical and Angiographic Evaluation of Radiotherapeutic Response of Glomus Jugulare Tumors

In 3 patients with glomus jugulare chemodectomas, serial angiography was carried out prior to radiotherapy and up to two years afterward. Poor correlation was found between clinical and angiographic response to treatment. Because good clinical response need not be accompanied by a corresponding change in angiographic appearance, the latter on a repeat late examination should not be considered a basis for additional radiotherapy. After therapy the vascular component of the tumor may produce continuing symptoms, and it appears to represent a separate therapeutic problem.
