We evaluated the improvement in the gray and white matter functional areas in children with cerebral palsy (CP) after common carotid artery sympathetic neural network ablation. We also analyzed the relationship between the values of the diffusion kurtosis imaging (DKI) parameters and clinical signs in children with CP. ⋯ Therefore, it can be concluded that DKI technology can more accurately reflect the gray and white matter damage in children with CP, and the DKI parameters can be used as a monitoring and evaluation index for children with CP.

The paper proposes an improved LANDMARC positioning algorithm to improve the location accuracy of environmental obstacles for medicine care monitoring in neurology. The paper proposes a log path loss correction model and uses the model to compensate the positioning signal to improve the positioning accuracy of the algorithm caused by the attenuation of the indoor positioning signal by the wall. The experimental results show that the LANDMARC positioning algorithm based on the log path loss correction model can improve the positioning accuracy of medical monitoring in neurology.

Case Reports
Calcifying pseudoneoplasm of the neuraxis (CAPNON) in the posterior third ventricle - a challenge for neuroendoscopy.
We report the first case of a purely intraventricular calcifying pseudoneoplasm of neuraxis (CAPNON) in the posterior third ventricle. ⋯ When encountering such calcified lesions within the ventricular system, especially in proximity to eloquent regions, the decision making process should include the hard consistency and parenchymal adhesions as obstacles to neuroendoscopic removal. Even for biopsy, a higher morbidity rate compared with typical soft tumors should be assumed. Although data on intraventricular CAPNON is limited, biopsy of the lesion and treatment of associated hydrocephalus appear to be the primary neurosurgical goals, followed by imaging surveillance.

The operative microscope, a commonly used tool in neurosurgery, is critical in many supratentorial tumor cases. However, use of operating microscope for supratentorial tumor varies by surgeon. ⋯ Use of operative microscope for supratentorial resections varies by state and is associated with higher cost of surgery. Microscope use may be associated with lower rates of intraoperative cerebral edema and some cerebrovascular complications, but is not associated with significant differences in other complications, readmissions, or 30-day costs.
