Recognition of congenital tethered cervical cord in adults and literature review. ⋯ Neurocutaneous stigmata should not be considered benign. A missed clinical diagnosis was apparent in all 3 patients; 2 of whom underwent surgery with excellent results. MRI can identify the abnormal cervical cord protruding towards the "sinus tract" and allow planning to avert injury to the spinal cord during release.

The paper uses clinical neuropsychological testing methods and resting state functional MRI technology to investigate whether chemotherapy can cause cognitive impairment and/or changes in local brain activity in breast cancer patients. In the thesis, 21 breast cancer patients (stage Ⅰ-Ⅲ) who had not undergone radiotherapy and adjuvant chemotherapy were confirmed by clinical surgery and pathology, with an average age of (50.14±13.12) years. Perform 6 neuropsychological tests before chemotherapy and 1 month after chemotherapy, conventional horizontal axis T2-weighted fluid attenuation inversion recovery (T2-FLAIR) sequence, plane echo imaging blood oxygen level dependent (EPI-Bold) functional sequence collection. ⋯ One month after chemotherapy, the brain areas with increased ALLF in breast cancer patients include: left inferior temporal gyrus, right middle temporal gyrus, left middle temporal and upper gyrus, and bilateral praecuneus. In breast cancer patients, memory, attention, executive function and processing speed are reduced in the short term after conventional chemotherapy. Chemotherapy changes the neural activity of the resting local brain areas, mainly the increased activity of the bilateral anterior cuneiform and middle temporal gyrus, which is the brain area that constitutes the default network (DMN).

Intraoperative magnetic resonance imaging (iMRI) has been shown to optimize the extent of resection of parenchymal brain tumors. To facilitate the use of preoperative treatment plans after an intraoperative navigation update via iMRI, an elastic image fusion (EIF) algorithm was developed. ⋯ This feasibility study shows that EIF can compensate for surgery-related brain shift in a highly significant manner even in this small number of cases. The establishment of an easy applicable and reliable EIF tool integrated in the clinical workflow could open a large variety of new options for image-guided tumor surgery.
