Computerized Tomography Demonstration of Purely Intracanalicular Acoustic Neuromas
نویسندگان
چکیده
Three cases of purely intracanalicular acoustic neuromas not causing bony erosion and/or enlargement of the internal acoustic canal walls diagnosed accurately by temporal bone CT examinations are presented. It is suggested that temporal bone CT scans done with the appropriate technique is a sufficient and

Air CT cisternography of anterior inferior cerebellar artery loop simulating an intracanalicular acoustic neuroma.
Acoustic neuromas larger than 1 cm are usually apparent on routine computed tomography (CT) after contrast enhancement, but smaller lesions escape detection [1, 2]. Metrizamide CT cisternography can demonstrate small lesions, but it is not accurate for the detection of intracanalicular lesions [1, 3]. Pantopaque meatocisternography can detect intracanalicular lesions but has a high percentage o...
متن کاملMR imaging of the acoustic nerves and small acoustic neuromas at 0.6 T: prospective study.
To evaluate the capability of magnetic resonance (MR) in imaging normal acoustic nerves, 12 volunteers without signs or symptoms of intracranial disease were examined using a 0.6 T superconductive system. Several spin-echo (SE) pulse sequences were tested to identify the optimal sequence for demonstration of the acoustic nerve bundle. Repetition times (TRs) varied from 300 to 2000 msec and echo...
متن کاملGas CT cisternography of an intracanalicular vascular malformation.
Gas CT cisternography has been shown to be an excellent technique for diagnosing intracanalicular acoustic neuromas [1, 2]. While other intracanalicular lesions, such as meningiomas, hemangiomas, cholesteatomas, gliomas, and hamartomas, are much less common, they do occur [3-6]. We describe the cisternographic findings in a patient with a purely intracanalicular vascular malformation and point ...
متن کاملAir-CT cisternography and canalography for small acoustic neuromas.
Disenchantment with the limitations, and in some cases the morbidity, of currently used radiologic techniques for the demonstration or exclusion of small acoustic neuromas prompted development of an examination using small amounts of intrathecal air and computed tomography (CT). A prospective study was designed to evaluate air CT cisternography/canalography, wherein patients with the clinical s...
متن کاملClinics in diagnostic imaging.
A 48-year-old Chinese woman presented with progressive right-sided sensorineural hearing loss. Computerised tomography showed asymmetrical widening of the right internal acoustic canal. Post-gadolinium magnetic resonance images demonstrated marked enhancement of an intracanalicular tumour. The diagnosis of acoustic neuroma was confirmed surgically. The approach to imaging of deafness, particula...
