Male, 2 years old, with macrocephaly and increasing head size, developmental delay, sacral dimple. Evaluate for hydrocephalus, tethered cord, or other spinal cord abnormal. Brain:Parenchymal morphology is within normal limits. No tissue defects are seen. No evidence of any dysplasia or migrational anomaly is detected. No pathologic signal abnormality is seen including no evidence of diffusion restriction. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricular system is normal in size and morphology. The pattern of intracranial enhancement is within normal limits. The paranasal sinuses and right mastoid air cells are opacified.Spine:A full complement of normally formed vertebral bodies is seen. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No pathologic marrow replacement or edema is detected. Within the limitations of motion degradation, the spinal cord, conus and cauda equina are within normal limits. The conus tip terminates at the L1-2 level which is within normal limits. On prone imaging, the conus and cauda equina demonstrate normal anterior translation. No evidence of fatty filum terminale or any other fatty intraspinal lesion is detected. No epidural abnormalities are seen. The intervertebral discs are preserved with no areas of spinal canal or foraminal compromise.
1.Unremarkable evaluation of the brain and spine. Specifically, no evidence of hydrocephalus or tethered cord is seen.2.Opacification of the paranasal sinuses and the right mastoid air cells is seen.
