sodium-pertechnetate-tc-99m and Glomus-Jugulare-Tumor

Jugular paraganglioma is a highly vascular tumor, slowly growing, extending into the surrounding structures and causing otologic and/or neurologic symptoms according to its location in the jugular bulb region or the middle-ear. In our study, modified vertex and posterior head scintiangiography was used in seven cases. Scintiangiography was positive in all seven, whereas concomitant radiographic studies were limited: four of the seven gave positive findings by transmission computerized tomography (TCT). Only four patients underwent angiography, with positive results in two. Hypocycloidal tomography was positive in three cases. However, some radiographic studies, particularly TCT, may be useful in detecting local extension, bone destruction, and soft-tissue infiltration. Radionuclide angiography proved highly reliable and should be used initially whenever a jugular paraganglioma is suspected.
