[Scintigraphy in the diagnosis of tumors of the 8th cranial nerve].
The indications for and the diagnostic value and the method of radioisotope gammaencephalography (GEG) in tumors of the 8th nerve and similar diseases (47 cases) were studied. The optimum time for conducting scintigraphy for the detection of tumors of the 8th nerve is 2 1/2-3 hours after injection of the isotope. Small tumors up to 2 cm in size are not revealed by GEG, stage II and stage III tumors are clearly demonstrated. GEG makes it possible to differentiate tumors of the 8th nerve from arachnoiditis of the cerebellopontine angle and stem encephalitis.
