To report the case of a pediatric patient with intramedullary spinal aneurysm. ⋯ To our knowledge, this is a first report of an intramedullary spinal cord aneurysm at the cervical-thoracic junction in a pediatric patient. Careful observation after initial symptoms followed by surgical intervention was favorable in this case.

The use of conventional percutaneous endoscopic lumbar discectomy (PELD) for high-grade down-migrated lumbar disc herniation medial to the pedicle via the transforaminal route can result in less favorable outcomes. We report a new PELD technique for the treatment of high-grade down-migrated lumbar disc herniation via a facet process and pedicle-complex approach. ⋯ PELD via a facet process and pedicle-complex approach may be an option for high-grade, down-migrated lumbar disc herniation with completely sequestrated nucleus pulposus.

Review Case Reports
Resolution of traumatic bilateral vertebral artery injury.
Cerebrovascular ischaemia is a rare but serious complication of damage to the carotid or vertebral arteries in the neck caused by blunt injury to the neck. Screening for blunt cerebrovascular injury should be performed in patients with certain signs or symptoms and risk factors. We described a case of traumatic bilateral vertebral artery injury (VAI) including unilateral vertebral arterial occlusion that resolved 3 months post-injury with antiplatelet and direct oral anticoagulant therapy. This resolution of traumatic bilateral VAI is very rare. Vertebral artery injury should be suspected in patients with displaced fracture dislocation of the cervical spine, particularly in the elder and those with ankylosing spondylitis, and therefore imaging of these patients should include a modality to look at the patency of the vertebral arteries. ⋯ A 70-year-old man who was diagnosed with ankylosing spondylitis collapsed and presented with tetraplegia. Computed tomography showed C3 fracture dislocation, and magnetic resonance imaging showed a high-signal intensity and intense compression of the spinal cord from C2 to C3. Cerebral angiogram showed left vertebral artery occlusion and right vertebral artery stenosis. Heparin was administered to prevent posterior circulation stroke and he underwent posterior fixation. Three months post-injury, a cerebral angiogram showed the resolution of the bilateral VAI.

Review Case Reports
Intradural cervical chordoma with diffuse spinal leptomeningeal spread: case report and review of the literature.
Chordoma is a low-grade malignant bone tumor derived from embryonic notochord remnants along the axial skeleton. About 50% of chordomas occur in the sacral vertebrae and 35% in the skull base. Most chordomas are extradural and cause extensive bone destruction. Intradural spinal tumors without bone involvement are rare. ⋯ An intradural spinal chordoma is difficult to distinguish from a neurogenic tumor by imaging. When the lesion is dumbbell-shaped, it is easily misdiagnosed as a schwannoma. In the present case, the tumor was intradural and located at the level of the C6 and C7 vertebrae. Preoperative diagnosis was difficult, and the final diagnosis required pathological examination.

To study the known or suspected risk factors for sciatica: Tallness, overweight, smoking, leisure-time physical exercise, self-reported health and occupation, and how they predict hospitalizations due to sciatica. Only a few cohort studies have previously focused on the risk factors for sciatica. ⋯ Physically demanding work is a strong risk factor for sciatica. Leisure-time physical activity seems to protect men against sciatica, while overweight is a risk factor among women. However, occupation substantially modifies these associations.
