 The internal auditory canals are symmetrical and normal in size and signal intensity. The inner ears are normal, with normal T2 signal and no pathological enhancement. No abnormal mass or abnormal enhancement is seen within the cerebellopontine angle, cisterns bilaterally or within the internal auditory canals. The seventh and eighth cranial nerves are visualized bilaterally, although the left cochlear nerve is slightly better visualized than the contralateral side, which may be technical in nature. Please note that evaluation is limited sagittal obliques through the IACs were not submitted for review.There is mild nonspecific prominence of the ventricles, especially the lateral and third ventricles. There is only minimal prominence of the anterior subarachnoid space, greater on the right side. The cisterns remain patent. There is no midline shift or mass effect. There are no areas of abnormal signal or pathological enhancement. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
1. Unremarkable contrast-enhanced MR appearance of the IACs. Seventh and eighth cranial nerves are visualized bilaterally, with better visualization of the left cochlear nerve likely technical in nature. Evaluation somewhat limited due to lack of sagittal obliques through the IACs.2. Nonspecific mild prominence of the ventricles with less conspicuous prominence of the anterior subarachnoid spaces, greater on the right side. Findings could relate to benign enlargement of subarachnoid spaces of infancy we should resolve by two years of age. Follow-up imaging may be obtained as clinically indicated.
