Review Case Reports
Intracranial non-skull-based chondrosarcoma arising from the sagittal sinus: a case report and review of literature.
Intracranial nonskull-based chondrosarcoma is a very rare malignant tumor. In fact, it is difficult to diagnose because of its atypical radiologic and morphologic features. We report a case of an intracranial parasagittal chondrosarcoma in the left parietal lobe accompanied with significant peritumoral edema (an extremely rare phenomenon for this tumor), with a review of the literature, to clarify aspects in the diagnosis of this rare tumor. ⋯ Although magnetic resonance imaging was performed, it is sometimes difficult to distinguish intracranial chondrosarcoma from meningioma and glioma, especially when the tumor arises from a nonskull base such as the meninges. Some cases could have significant peritumoral edema, although it is extremely rare. Histologic examination may aid in the diagnosis of this tumor. Neurosurgery is the most effective therapy for these tumors. Postoperative radiotherapy needs to be considered when the tumor is incompletely resected, has atypical histology, or is associated with significant peritumoral edema.

Multicenter Study
Intra- and Peri-operative Complications Associated with Endoscopic Spine Surgery: A multi-institutional study.
To report on intra- and perioperative complications associated with working channel endoscopic spine surgery. ⋯ Endoscopic spine surgery is associated with a favorable rate of intra- and perioperative complications compared with reported rates of minimally invasive ortraditional open spine surgeries. Our report proposes safe and effective strategies for management of these complications.

Review Case Reports
A rare case of spinal cavernous hemangioma dumbbell shaped and a literature review.
Spinal epidural cavernous hemangiomas are rare vascular malformations. Exceptionally, they present with dumbbell-shaped morphology. When they happen, it's mandatory to include their pathology in the differential diagnosis because of their similarity to schwannomas. ⋯ Surgery is safe and effective in both improving patient condition and preventing acute hemorrhage that can worsen the outcome, causing neurologic and potentially irreversible deficits. The favorable result we obtained in our patient suggests that surgery should be evaluated as the first option, even in patients with large epidural cavernous hemangiomas.

Review Case Reports
Large intraosseous lipoma of the skull:A case report and review of the literature.
Intraosseous lipomas occurring within the skull are rare. Currently, the known locations include the frontal bone, parietal bone, temporal bone, and ethmoid bone. Thus far, we have found only 12 cases of lipoma at the top of the forehead on the skull, and only 2 cases of recurrent intraosseous lipoma have been reported. The patient with intraosseous lipoma we have described was a 3-year-old boy, the youngest of the 12 known patients with intraosseous lipoma of the skull, and the patient had repeated relapses. ⋯ For large intraosseous lipomas occurring in the skull, owing to its special position and the tendency for repeated relapses to develop, extending the excision is an effective surgical approach. For swelling involving a wide range, surgery should involve specialists in craniofacial surgery.

Randomized Controlled Trial
Wallis Interspinous Spacer for treatment of primary lumbar disc herniation: three-year results of a randomized controlled trial.
Limited data have been reported showing whether the second-generation Wallis interspinous spacer improves function after lumbar spine decompression or discectomy. ⋯ We found that discectomy combined with Wallis implantation was not beneficial for pain relief or lumbar function improvement compared with lumbar discectomy alone. Although the Wallis implant was associated with maintenance of the intervertebral disc height and limited range of motion of the spine, it is probably incapable of preventing recurrent herniation or adjacent segment degeneration.
