Few data are available concerning clinical outcomes in patients with Parkinson disease who undergo elective thoracolumbar spine fusion surgery. The goal of this study is to elucidate complication and revision rates after posterior thoracolumbar fusion surgery in patients with Parkinson disease, with a focus on how Parkinson disease modifies these rates. ⋯ Patients with Parkinson disease are more likely to require revision surgery and have higher rates of adverse medical events postoperatively. Patients with Parkinson disease should be appropriately selected to ensure favorable clinical outcomes.

Ulnar neuropathy at the elbow (UNE) is the second most common mononeuropathy of the upper extremity. One rare cause of UNE is nerve mass lesions, including intraneural ganglion cysts (IGCs). IGC imaging studies provide important information that may determine the nature of a peripheral nerve mass lesion. ⋯ This case demonstrates that MRI studies indicating malignant peripheral nerve sheath tumor must be considered with some caution and corroborated with supportive features on operative inspection and biopsy before radical resection is undertaken. Furthermore, for any nerve mass lesion immediately adjacent to a joint, the differential diagnosis of an IGC should be considered.

Neurenteric cysts are rare central nervous system lesions derived from an endodermal origin. There is no consensus concerning pathogenesis because of the paucity of occurrences. We report an immunohistochemical study of 10 cases with neurenteric cysts and postulate its pathogenesis. ⋯ We postulate that the cystic tumor was derived from multipotent endodermal cells that migrated and traveled along the neuroectoderm, with incomplete differentiation into various cell types as a result of an unsuitable microenvironment. Because the neurenteric canal was only the channel of migration rather than a component of the cysts, the term neuroendodermal cysts is more precise in presenting the embryopathogenesis.

To assess several different cervical alignment parameters to determine the clinical relationship between cerebral palsy (CP) with cervical spondylotic myelopathy (CSM) and cervical deformity. ⋯ Surgical treatment for patients with CP CSM deformity helped alleviate symptoms. Postoperative NDI scores and hand function improved in patients with CP CSM deformity, especially those in the corrected group. Clinicians should consider correcting the deformity in patients with CP CSM.

Case Reports
A traumatic spinal perimedullary arteriovenous fistula induced by a cervical glass stab injury.
In the literature, perimedullary arteriovenous fistula (AVF) is an uncommon spinal vascular malformation that is generally regarded as a congenital lesion. To our knowledge, only a few cases of traumatic perimedullary AVF have been reported in the literature so far. ⋯ Cervical trauma should be considered as a possible cause of de novo perimedullary AVF. Recognition of this phenomenon is important.
