Chiari malformation, developmental delay with speech, evaluate for syrinx or tethered cord: Chiari malformation spine survey for abnormalcies. The cerebellar tonsils extend up to approximately 15 mm inferior to the foramen magnum and demonstrate a peg-shaped configuration with impeded CSF flow in this area. There is mild retroflexion of the dens. The vertebral column alignment is otherwise within normal limits. The spinal cord displays normal signal and morphology, without evidence of syringohydromyelia. The conus medullaris is located at the L1-2 level. The vertebral body and disc space heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The paravertebral soft tissues are unremarkable.
Findings compatible with Chiari I malformation, but no evidence of syringohydromyelia or low-lying conus medullaris.
