Male, 2 years old, with sensorineural hearing loss. The periventricular white matter in the cerebral hemispheres appears to be thinned relative to the typical normal appearance for this age group. Similar findings are seen on the prior outside MRI. A single small focus of FLAIR hyperintensity is noted within the right frontal operculum, and there may also be minimal FLAIR hyperintensity in the white matter surrounding the right frontal horn. No pathologic parenchymal or extra-axial enhancement is detected.Brain morphology is otherwise within normal limits. The corpus callosum is fully formed and intact. The extent of white matter myelination has progressed relative to the prior examination and is within acceptable limits for age. No edema or mass effect is seen. No restricted diffusion or evidence of intracranial hemorrhage is noted. The lateral ventricles are mildly prominent, left side more than right, which could be reflective of the above-mentioned white matter thinning.On dedicated imaging of the IACs, the fluid-filled structures of the inner ear are within normal limits. The cochlear nerves are present bilaterally. No pathologic IAC or CP angle enhancement is detected.
1.Findings suggestive of mild periventricular white matter thinning, not significantly changed from the prior outside examination. No acute intracranial abnormalities are detected.2.On dedicated IAC imaging, no specific abnormalities are detected. The cochlear nerves are present bilaterally.
