Hi, Thanks for writing in. The internal acoustic meatus refers to inner ear area. The radiologist makes an observation that there is absence of fluid signals around the inner ear. This can mean that there is something occupying the area. If you have problems with hearing and balance then this can suggest the possibility of an acoustic neuroma which is a benign tumor usually seen in that location. Right now the presence of acoustic neuroma is not confirmed. You should get a repeat MRI scan done after few months but within one year to know any well defined benign tumor like lesion in the region. Since it is very small and diagnosis is still not confirmed, you should not get worried about it now. Since there is no destructive changes in the area, the possibility of a malignant or life threatening condition is not there. However close follow up of the MRI findings is required under the guidance of your doctors.
