Auditory Brainstem Response test (ABR): Sensitivity and Specificity
Introduction:
None written. Excerpt from the entry in Acoustic neuroma:
Abnormal ABR, measured by CN V latency
Abnormal ABR, measured by CN V latency
This test can be helpful both in diagnosing acoustic neuromas and also in identifying such tumors that are amenable to resection with salvage of hearing
Note: In the following study based on 51 patients with acoustic neuromas the sensitivity was higher for extracranial tumors (24/25 = 96%) than for intracranial tumors (10/15) = 67%
Associated Diagnoses:
85% sensitive
