title: [Four cases of carotid body tumor--especially the usefulness of CT and MRI in preoperative diagnosis].
abstract: Four cases of carotid body tumor are reported. Surgical removal of the tumor was performed in all cases. The internal carotid artery (ICA) was preserved in only two cases. In the other two cases ICA was unavoidably replaced by an EPTFE (expanded polytetrafluoroethylene) graft. In addition to the size and mobility in the anterior and posterior direction of the tumor, we concluded that CT and MRI were useful in decision of the surgical method. In case the ICA cannot be distinguished from the tumor at the bifurcation of the carotid artery on enhanced CT, it should be considered to be difficult to remove the tumor. MRI is suitable for discerning the inner surface of the carotid artery, but it is significant that MRI cannot necessarily reveal tumor invasion of the carotid artery wall.
