Symptomatic calcification of the ligamentum flavum (CLF) is common in the cervical spine but rare in the thoracic spine. Rapidly progressing CLF in the thoracic spine has not been reported in the literature. ⋯ In this case, sequential imaging studies with a 9-month interval showed evidence of rapidly progressing thoracic CLF. The preceding osteoporotic vertebral fracture may have triggered the development of CLF.

Intrameningioma metastasis is a rare differential diagnosis. The clinical implications of these lesions are poorly understood. We screened our database to identify all patients who had been undergone surgery between January 2000 and December 2018 and had been diagnosed with intrameningioma metastasis. Medical charts and radiographic images were reviewed. Brain edema was related to tumor size on preoperative T2-weighted magnetic resonance imaging and classified as little (i.e., less than the tumor size), moderate (i.e., less than triple the size of the tumor), and extensive (i.e., more than triple the size of the tumor). ⋯ Intrameningioma metastases show an aggressive clinical behavior prompting early surgical intervention. Clinicians should be aware of this rare entity when counseling patients.

To assess the in vivo longitudinal kinematic performance of the Prestige-LP Disc and describe the 5-year trends in the center of rotation (COR) at the instrumented level. ⋯ Single-level CDA with the Prestige-LP Disc achieved favorable clinical outcomes and provided a durable solution for spinal motion at the instrumented level. The COR showed a significant cranial shift after surgery and remained relatively stable during the 5-year follow-up period.

Primary Ewing sarcoma of the mobile spine is a rare disease. Its management requires careful surgical planning, because radical, margin-free excision is directly correlated with prognosis. Extensive bone removal in the cervical spine can lead to instability and cause postoperative iatrogenic cervical deformity. Thus, spinal instrumentation plays an important role in restoring postresection spinal stability and improving quality of life. ⋯ This technique enables 1-stage total tumor resection and stabilization and may be a viable alternative to radical en bloc resection of posteriorly located epidural malignant lesions of the cervical spine in selected cases.

Comparative Study
Comparison of clinical and radiological characteristics and prognosis of chronic subdural hematoma patients with and without a history of head trauma.
To compare clinical and radiologic characteristics and prognosis of patients with chronic subdural hematoma (CSDH) with and without a history of head trauma. ⋯ Patients with CSDH with or without a history of head trauma presented with different clinical and radiologic characteristics. Patients with CSDH without a history of head trauma had a higher mortality and lower GOS score, which indicates these patients warrant more attention.
