Female, 2 years old, with vertigo. Assess for inner ear disturbance or vestibulitis. Mild patchy periatrial T2 hyperintensity is seen, somewhat more than expected for normal variation. No evidence of significant volume loss, mass effect, edema or pathologic parenchymal enhancement is seen. No diffusion restriction is noted.No evidence of any heterotopia or migrational anomaly is seen. The pattern of white matter myelination is appropriate for age. The corpus callosum is well formed and intact. The brainstem, cerebellar vermis and cerebellar hemispheres are unremarkable. The pituitary gland is also within normal limits.The visualized cranial nerves, including the 7th and 8th nerve complexes, are within normal limits. No IAC or CP angle masses are detected. The fluid-filled structures of the inner ear demonstrate normal morphology. No gross pathologic IAC or inner ear enhancement is suspected, though please note that imaging technique is not adequate to detect subtle or small enhancing lesions.Paranasal sinus mucosal inflammation is noted incidentally.
1.Mild periatrial white matter lesions are suspected with no associated mass effect, volume loss or pathologic enhancement. These are nonspecific and may represent the sequelae of some remote insult.2.The overall morphology of the brain, and the pattern of white matter myelination, are appropriate for age.3.No definite evidence of any IAC lesion is suspected on the basis of this examination. If clinical concern persists, a dedicated IAC examination with thin section postcontrast images may be considered.
