Figure 1 MRI features before treatment A, F: multiple cystic high signals (red arrow) can be seen in the subcortical white matter area of the T2 weighted image; B, G: the corresponding area of T2 weighted fluid-attenuated inversion recovery sequence is hypointensity (red arrow); C, H: the T1 weighted image is hypointensity; D, I: the diffusion-weighted imaging has no diffusion restriction (red arrow); E, J: the T1 weighted image sagittal position shows a hypointensity cystoid signal in the frontoparietal lobe. The lesions are mainly distributed in the subcortical white matter area. Bilateral frontal and parietal extracerebral spaces widened.

Figure 2 MRI features after treatment A 1-year-old child with 3 courses of acupuncture treatment, Compared with the MRI images before acupuncture treatment, the abnormal signals of long T1 and long T2 in the subcortical white matter area of bilateral frontal and parietal lobes and the range of frontal and parietal subdural effusion were significantly reduced (white arrow). The sulcus fissure and lateral ventricle were still widened, showing the change of "brain atrophy" (red arrow). A, F: T2 weighted image showed that a small amount of flaky hyperintensity was still visible in the white matter area under the parietal cortex on both sides; B, G: the corresponding area of T2 weighted fluid-attenuated inversion recovery sequence showed hypointensity (red arrow); C, H: T1 weighted image showed a hypointensity; D, I: the diffusion-weighted imaging had no diffusion limitation; E, J: a slit-like hypointensity can still be seen in the parietal lobe at the T1 weighted image sagittal position.
