Fig 4. Sagittal oblique (A), coronal (B), and transverse (C) MDCT sections from a neonate specimen. The middle otic layer is seen as a smooth hypoattenuation around the cochlea, circumscribed by the attenuated inner and outer layers. A well-defined hypoattenuated focus (arrow) is seen in the anterior otic capsule, communicating laterally with the middle layer and medially with the petro-occipital fissure.
