Syndrome of the trephined (ST) is a post-craniectomy complication. It is characterized by the appearance of new neurological symptoms following the craniectomy, which are relieved after cranioplasty. The purpose of our work was to identify radiological signs and imaging biomarkers of the ST. ⋯ ST is an infrequent and delayed post-craniectomy complication. The most common radiological findings (paradoxical herniation, deviation of the midline structures, and sunken skin flap sign) might not be specific for ST. Significantly lower 3rd ventricle, and relative intracranial CSF volumes, suggest that altered biophysical CSF properties underlie ST pathophysiology. Therefore, volume measurements of 3rd ventricle could be useful for identification of patients who have higher probability of developing the ST.

Diffusion tensor imaging (DTI) as a potential technology has been used in spinal cord injury (SCI) studies, but the longitudinal evaluation of DTI parameters after SCI, and the correlation between DTI parameters and locomotor outcomes need to be defined. ⋯ FA was sensitive to degeneration in white matter and DTT could directly reflect the distribution of the residual white matter. Moreover, days 1 to 3 post-SCI may be the optimal time window for SCI examination and therapy.
