Review Case Reports
Primary NK/T-cell lymphoma of the cauda equina: a case report and literature review.
A case report with a review of the literature. ⋯ Although primary lymphoma of the cauda equina is extremely rare, the prognosis of this condition is thought to be poor. Early definitive diagnosis with examination of the cerebrospinal fluid followed by combined treatment with radiotherapy and high-dose methotrexate should be considered.

A case report of a young male suffering progressive neurologic dysfunction associated with a previously unreported combination of structural bony abnormalities. A review of the literature is also presented. ⋯ Posterior deficiencies of the atlas and axis are rare occurrences in isolation, let alone in the 1 patient. This report broadens the radiographic differential diagnosis of patients presenting with cervical myelopathy, which has been associated with congenital posterior C2 anomalies in only a handful of patients. Surgery is an appropriate option for these patients faced with progressive neurologic dysfunction.

Retrospective analysis of preoperative imaging and clinical data from patients undergoing cervical expansive laminoplasty for cervical myelopathy. ⋯ Intraoperative US was more useful than postoperative MRI for predicting the clinical outcome of cervical expansive laminoplasty. Knowledge of the predictive parameters for spinal cord floating after cervical expansive laminoplasty could help evaluate the limitations of posterior decompression.

A biomechanical study using human cadaveric thoracolumbar spinal columns. ⋯ New vertebral fractures occurred at the vertebra adjacent to augmented vertebrae in the P group and in the augmented vertebrae in the C group. The difference in the fractured site may be because of the difference in strength between the 2 bone filler materials. Therefore, the strength of bone filler materials is considered a risk factor in developing adjacent vertebral body fractures after VP.

Case series. ⋯ Ultrasound-guided L5 nerve root block using electrical nerve stimulation is a safe and effective method.
