Summary:

Description	Radiopaedia case ID: 79290 Image ID: 52977032 Image stack position: 5/11 Plane projection: Sagittal Aux modality: T2 Study description: Whole spine Study findings: Low lying tethered cord is noted, tethered to the posterior surface of L5 spinal canal. No mass lesion is noted at the level of tethering. Modality: MRI System: Central Nervous System Findings: MRI brain shows midline occipital bony defect (1.9 x 1.6 cm) with herniation of cerebellar vermis and portion of left cerebellar hemisphere through the defect. The herniated brain parenchyma is surrounded by large CSF intensity fluid collection (9 x 11 x 9 cm). These features are consistent with large occipital meningoencephalocele. There is traction on posterior fossa structures with anteroposterior elongation of fourth ventricle, resulting in moderate bilateral lateral and third ventricular dilatation.
