To investigate the complication rates and long-term implant failure rates in a monocentric study of a consecutive cohort of patients with thoracolumbar spinal metastases after posterior instrumentation with a fenestrated carbon fiber-reinforced poly-ether-ether-ketone (CFRP) pedicle screw system. ⋯ Percutaneous cement-augmented CFRP pedicle screw instrumentation facilitates artifact-reduced postoperative imaging, while maintaining a risk profile and implant failure rates comparable to conventional metallic instrumentation.

Chronic subdural hematoma (cSDH) is a common pathology, and recurrence is a common complication, which may be predicted by certain patient and radiologic factors. Empiric radiologic surveillance has been shown to convey no benefit. ⋯ Certain radiologic findings may predict the recurrence of cSDH following evacuation. The score derived may be useful in identifying patients who might benefit from routine postoperative surveillance imaging.

Meningioma is the most common primary brain tumor in adults. In recent years, several non-neurofibromin 2 mutations, i.e., AKT1, SMO, TRAF7, and KLF4 mutations, specific for meningioma have been identified. This study aims to analyze the clinical impact and imaging characteristics of the KLF4K409Q mutation in meningioma. ⋯ The KLF4K409Q mutation is associated with a distinct small tumor subtype, prone to substantial PTBE. EI is a reliable parameter to predict the KLF4K409Q mutation in meningioma, thus providing a tool for improvement of pre- and perioperative medical management.

Owing to prolonged hospitalization and the complexity of care required for patients with aneurysmal subarachnoid hemorrhage (aSAH), these patients have a high risk of complications. The risk for wound infection after microsurgical treatment for aSAH was analyzed. ⋯ Microsurgical treatment for aSAH is associated with a relatively low risk of wound infection. However, patients undergoing DC may be at an increased risk for infection. Additional attention and comprehensive wound care are warranted for these patients.

We report a middle-aged man with a history of traumatic cervical spinal cord injury with extensive edema. Decompressive surgery of posterior laminectomy and fixation was performed. An irreparable dural rupture on dorsal-lateral side of the cord was found during operation. ⋯ Half a year later, however, the patient presented with C5 nerve palsy. Magnetic resonance imaging revealed cervical spinal cord herniation with pseudomeningocele. Late postoperative cervical spinal cord herniation with pseudomeningocele may occur in any cervical spine trauma cases with dural rupture and/or defect, and close follow-up and observation are needed in the postoperative period.
