Acoustic neuromas: evaluation by magnetic resonance imaging.
Proton magnetic resonance imaging (MRI) examinations were performed in six patients with seven acoustic neuromas, and the results were compared with conventional tomography of the internal auditory canals, contrast-enhanced computed tomography (CT), and air CT cisternography. All tumors were identified with MRI. The three largest tumors (greater than 1 cm diameter) looked similar to the tumors ...
متن کاملInternal auditory canal involvement of acoustic neuromas: surgical correlates to magnetic resonance imaging findings.
OBJECTIVE Factors that play a role in the selection of surgical approach for acoustic neuromas include patient health and age, size of tumor, hearing status, and location of tumor in the internal auditory canal (IAC) and the cerebellopontine angle. Deep extension into the IAC makes hearing preservation extremely difficult when a retrosigmoid craniotomy is used, and the best approach is a middle...
متن کاملThe sensitivity of auditory brainstem response testing for the diagnosis of acoustic neuromas.
OBJECTIVES To determine the sensitivity of auditory brainstem response (ABR) testing for detecting acoustic neuromas and to determine whether the test is less sensitive for detecting small tumors. DESIGN Retrospective review of the medical charts of 58 patients with acoustic neuroma who had all of the data necessary for inclusion in the study. SETTING University-affiliated referral practice...
متن کاملCost-effective initial screening for vestibular schwannoma: auditory brainstem response or magnetic resonance imaging?
OBJECTIVE Our goal was to determine the cost-effectiveness of including auditory brainstem response (ABR) testing in a screening protocol for the diagnosis of vestibular schwannoma (VS) in patients with asymmetric auditory symptoms at the Christian Medical College and Hospital, Vellore, India, where, commonly, patients with VS have tumors greater than 2 cm at the time of diagnosis. METHODS Ni...
