Review Case Reports
Surgical treatment in a patient with Klippel-Feil syndrome and anterior cervical meningomyelocele: a case report and review of literature.
Klippel-Feil syndrome (KFS) is considered a rare developmental disorder characterized by mono- or multisegmental fusion of the cervical vertebrae which is frequently associated with diverse non-osseous, e.g. neural, visceral, cardiopulmonary and genitourinary development anomalies. Anterior cervical meningomyelocele (MMC) in KFS has only been described in two previous patients, both with non-surgical treatment. ⋯ KFS with anterior cervical MMC is rarely seen and may require surgery in case of clincial signs of nerve root compression or myelopathy. Osseous decompression, untethering and adhesiolysis under electrophysiological monitoring can provide sufficient radiological and clinical improvement.

Review Case Reports
Unusual association of intraspinal extramedullary teratoma with congenital scoliosis in an elderly adult: case report and literature review.
Intraspinal teratomas associated with congenital scoliosis are extremely rare, especially in an elderly adult. ⋯ Rare intraspinal teratoma should be included in the differential diagnosis of intraspinal mass, especially in patient with congenital scoliosis. Patient with mature teratoma may survive with out any symptoms in the long term. Progressing neurological deficit is a main indication for surgery. Excellent clinical outcomes could be achieved by surgical resection and dural sac decompression.

Case Reports
Spinal subdural hematoma as a complication of spinal surgery: can it happen without dural tear?
Post spinal surgery subdural hematoma is a rare entity. This is a report of a case of acute post-operative spinal subdural hematoma, without any dural injury. The case was managed expectantly and went on to complete resolution of the hematoma and full clinical recovery.

To evaluate L5 nerve root injuries caused by outwardly misplaced S1 pedicle screws. Pedicle screws remain the criterion standard for fixation of L5-S1 to correct lumbosacral instability. When inserting S1 pedicle screws, it is possible to injure the L5 nerve root if screws are inserted outwardly and the tip of the screw perforates the anterior cortex of the sacrum. Despite this risk, to our knowledge this type of injury has never been reported as a case series. ⋯ Surgeons should recognize that lateral inclination of S1 pedicle screws can cause L5 nerve root injury, which may require reinsertion of the screw, especially in cases where insertion is difficult because of overlapping surrounding muscle or bony tissue.

C1 laminectomy for retro-odontoid pseudotumor without atlantoaxial subluxation: review of seven consecutive cases.
A retro-odontoid pseudotumor is usually a reactive fibrocartilaginous mass associated with atlantoaxial subluxation (AAS). However, a retro-odontoid pseudotumor not associated with AAS, which undergoes spontaneous regression following C1 laminoplasty, has been reported. The purpose of this study was to report surgical outcomes of C1 laminectomy for retro-odontoid pseudotumor without AAS. ⋯ Our study, assessing the outcome of C1 laminectomy for retro-odontoid pseudotumor, found neurological improvement in all cases. Since all pseudotumors were reduced and additional AAS was not observed, C1 laminectomy for retro-odontoid pseudotumor, in the absence of AAS, is recommended as a therapeutic strategy.
