Male, 2 years old, with sensorineural hearing loss status post meningitis. Bilateral pathologic enhancement of the cochlea, vestibules, and to a lesser degree the semicircular canals is seen. The inner ear structures otherwise demonstrate normal morphology and T2 signal characteristics.No mass lesion or pathologic enhancement is evident in the IACs or CP angles. The eighth cranial nerves are present bilaterally. Questionable enhancement of the bilateral canalicular and the left cisternal segments of the facial nerve are seen. No abnormalities of the visualized brainstem are appreciated. Limited views of the brain again show prominence of the sulci and ventricles.
1.Bilateral pathologic enhancement of the cochlea and vestibular apparatus is seen. Findings are compatible with post meningitic labyrinthitis.2.The eighth cranial nerves are present bilaterally. There is questionable pathologic enhancement of portions of the bilateral facial nerve which may also be related to prior infection.
