![]() Optimal canal visualization may be obtained through a combination of rotation of the operating table away from the side of the surgeon and microscope positioning. CT of the internal auditory canal, pre and post contrast (16320). ![]() In this case, I do not appreciate evidence of enlargement of the brainstem, nor is there abnormal enhancement to suggest neoplasm. Exposure of Internal Auditory Canal Exposure of the IAC and its contents involves removal of the bone surrounding the posterior, superior, and inferior aspects ( Figs. This is not unusual in the older age group (8th and 9th decades) and is sometimes thought to represent evidence of microvascular ischemic change.

Hazy increased intensity within the pontine tegmentum. Remainder of supratentorial portion of the brain is unremarkable. I do not appreciate other areas of subacute infarction. This would indicate that this represents limited subacute infarction. This is also hyperintense in the diffusion sequence but not in the ADC map. IMPRESSION: Small hyperintense area of the cortex of the right occipital lobe, as described above. Radiology CPT Code Complete x-ray examination of right internal auditory meatus. No abnormal contrast enhancement of brain parenchyma. This is not hyperintense in the diffusion sequence. However, there is bilateral irregularly shaped increased intensity within the pontine tegmentum. I do not appreciate significant abnormal increased or decreased intensity within brain parenchyma of the remainder of the supratentorial brain. This area is not hyperintense in the ADC map. The MRI was completed, and the MRI report that was dictated reads: MRI of the brain and internal auditory canals w/o contrast. This is also bright in the diffusion sequence. In the spin density and T2-weighted sequences (images 17 and 18 of series 3), there is a small localized area of occipital cortex that shows increased intensity.
