25 сент. 2024 г. · Vestibular schwannomas, also known as acoustic neuromas, are relatively common tumors that arise from the vestibulocochlear nerve (CN VIII)
This method usually demonstrates acoustic neuromas of 1.5-2 cm in diameter and, with high-resolution techniques, can reveal neuromas smaller than 1 cm [1 , 2).
20 июн. 2023 г. · Magnetic resonance imaging (MRI) with contrast dye is usually used to diagnose an acoustic neuroma. This imaging test can detect tumors as small ...
[10,16] Sections are typically 1.5 to 3.0 mm thick, allowing tumors as small as 0.05 cm3 to be detected.
On a T1-weighted MRI without contrast, an acoustic neuroma typically appears as an isointense or slightly hypointense mass relative to the surrounding brain ...
1 июн. 1987 г. · In four patients, MR imaging demonstrated five acoustic nerve tumors ranging in size from purely intracanalicular to a 12 mm cisternal component ...
It is concluded that an imaging strategy intended to identify small intracanalicular acoustic neuromas cannot rely on fast spin echo T2 weighted imaging alone.
Acoustic neuroma is diagnosed using a hearing test (audiogram) and imaging (MRI). Treatment can include observation (watching and waiting), surgery or radiation ...
In a proportion of small acoustic neuroma patients, monitoring with magnetic resonance imaging shows no volumetric increase of tumour size over the years.
