Giant anterior arachnoid cyst associated with syringomyelia: implications for treatment and follow-up.
A case report of a unique anterior intradural spinal arachnoid cyst (ISAC) associated with syringomyelia. ⋯ This is the most extensive anterior ISAC associated with syringomyelia reported in literature until now. The treatment of extensive intradural extramedullary arachnoid cysts, especially for those located ventral to the spine and associated with syringomyelia, is still a matter of debate. In our case, fenestration and insertion of a cyst-subarachnoid shunt alone were not sufficient to restore normal CSF dynamics. In addition, we show that K-MRI may not be a proper method for postoperative follow-up of these lesions.

Case report. ⋯ Unlike most cases of primary intradural melanoma, this patient presented with unusual radiologic findings in the cervical spinal cord. The case described in the present study illustrates that primary spinal cord melanoma is rare and must be diagnosed with caution due to its variable clinical and radiologic presentation.

Motion analysis on video files that captured grip and release cycles with fingers. ⋯ Both uncoordinated finger motion and trick motion of the wrist were more frequent in myelopathy patients than in healthy controls, and uncoordinated finger motion was associated with severity of myelopathy, whereas trick motion was not associated with either severity of myelopathy or level of cord compression. These findings contradict the conventional idea that trick motion is associated with the severity of myelopathy.

A prospective study was performed. ⋯ The technique of TRSP approach is safe, effective, and offers some advantages over the classic posterior, anterior, combined anterior-posterior approach for some specific highly unstable thoracolumbar fractures.

New neurologic deficit after spinal surgery is a rare complication that must be promptly diagnosed and treated to reduce the risk of permanent neurologic disability. ⋯ Normal somatosensory-evoked potentials or motor-evoked potentials in a patient denying sensation of stimuli offer objective evidence of the psychogenic nature of the para/tetraplegia. This report describes a case in which psychopathology interfered with the outcome of a frequently used procedure for a well-defined, chronic, painful condition.
