A modified introducer guide wire for the delivery of mini-coils is described. Mini-coils can now be used through standard tapered catheters with an inside diameter large enough to let pass of 0.97-mm (0.038-in) guide wire.
The appearance of six glomus tumors (four glomus jugulotympanicum and two vagal body tumors) is demonstrated in four patients. In one case, glomus tumor tissue is visualized by computed tomography (CT) inside the tympanic cavity. The importance of the use of different window settings is stressed. The value of CT in comparison to arteriography and polytomography is briefly discussed. Computed tomography is recommended in the evaluation of the course of a glomus tumor and in radiation therapy treatment planning of these tumors.
