Female, 10 years old, with right leg spasticity and weakness, syrinx. Brain:Small areas of subcortical T2 hyperintensity are seen within the left superior frontal, left middle frontal gyrus, and the anterior left temporal lobe. These lesions produce no mass effect and the overlying cortex shows normal signal intensity.No additional areas of focal signal abnormality, restricted diffusion or susceptibility effect are seen. Cerebral and cerebellar morphology is otherwise within normal limits. No evidence of intracranial hemorrhage or any abnormal extra-axial fluid collections are seen. Ventricular size and morphology are within normal limits.The left sphenoid sinus is completely opacified along with scattered ethmoid air cells. There is trace fluid signal in the mastoid air cells.Spine:Expansion of the central canal of the spinal cord is seen beginning at T10-11 and continuing down to T12-L1. The maximum caliber of the central canal measures 3 x 3 mm. Above the T10-11 level, there is minimal prominence of the central canal which can be normal.The spinal cord is otherwise normal in morphology and signal characteristics. The conus tip terminates at L1-2. No evidence of fatty filum terminale or other intrathecal fatty lesion is seen. On prone imaging, there is clear anterior shifting of the conus and cauda equina.Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. There is a normal complement of intact vertebral bodies. The intervertebral discs are preserved with no areas of significant spinal canal or foraminal stenosis.
1.Scattered small areas of signal abnormally are seen in the subcortical white matter of the left frontal lobe and the anterior left temporal lobe. These lesions are nonspecific but could potentially represent areas of gliosis related to prior traumatic injury, or prior inflammation/infection. No acute intracranial abnormalities are detected.2.Syringohydromyelia of the lower spinal cord is seen with a maximum caliber of 3 x 3 mm. The spinal cord is otherwise unremarkable, and there are no findings to suggest tethered cord. The osseous spine is within normal limits.
