[Cochleomeatal scintigraphy].
High resolution cochleomeatal scanning has proven to be a simple and inexpensive diagnostic method in tumors of the inner auditory canal, resp. of the cerebello- pontineangle . In 112 neurotologic patients (37 with proven acoustic neuromas) there were no false positives or false negatives. Therefore, the use of invasive or expensive tests in suspicion of tumors of the 8th cranial nerve should be restricted to those cases with positive scans. CMS is of special diagnostic value in patients with absent air insufflation of the basal cisternae in gas computerised tomograms and in suspected tumor recurrences. Dynamic studies with determination of the radiopharmacokinetics of radiopharmacology reveal further differential diagnostic aspects.
