Global developmental delay, truncal hypotonia, and lower hyper-reflexia. Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. Mild patchy areas of T2 hyperintensity in the posterior periventricular white matter regions may represent terminal zones of myelination. The brain parenchyma and pituitary gland otherwise appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.Spine: The vertebral column alignment is within normal limits. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord displays normal signal and morphology. The conus medullaris lies at the L1-2 level. There appears to be fine linear T1 hyperintensity along the filum terminale at the L4-5 level. The paravertebral soft tissues are unremarkable.
1. No evidence of intracranial malformations.2. Apparent fine linear T1 hyperintensity along the filum terminale at the L4-5 level may represent a fibrofatty filum. The spine otherwise appears unremarkable.
