Although rare, spinal meningiomas may cause motor and sensory deficits or difficulty with bladder or bowel function due to spinal cord compression. Although hemorrhage of intracranial meningiomas is well documented, there are very few cases of hemorrhage or hematoma associated with spinal meningiomas in the literature. Spinal meningiomas have been reported to be associated with subdural, epidural, intratumoral, and subarachnoid hemorrhage, and usually in the setting of an inciting event such as lumbar puncture or anticoagulation therapy. ⋯ To the best of our knowledge, this is the first report in English literature of a patient who first develops symptoms from a spinal meningioma with spontaneous intratumoral hemorrhage presenting with acute paraparesis. Magnetic resonance imaging findings in retrospect match surgical intraoperative findings. Prompt surgical intervention can result in complete resolution of neurologic deficits.

Colloid cysts (CCs) are rare cystic lesions derived from the endoderm of the central nervous system. Although they appear most commonly in the anterior roof of the third ventricle, there are only a few reports of CCs located in the suprasellar region. Although CCs are considered to be slow-growing benign tumors, their developmental process remains unclear. ⋯ This case suggests that CC may be one of several possible diagnoses in patients who present with suprasellar cystic lesions. Even if CCs in the suprasellar region remain asymptomatic, radiological follow-up is required due to possible progressive enlargement of the cyst.

Spinal ependymomas are rare, with an incidence of 1 per 100,000. Given the paucity of data for higher grade II and III disease, the management and patterns of care require further investigation. ⋯ Approximately 40% of patients with grade III ependymomas do not receive immediate adjuvant therapy, which may be related to distance from a facility. Patients with this rare tumor may benefit from multidisciplinary care at facilities with a larger volume.

High-grade spondylolisthesis (HGS) is a complex clinical problem that poses significant challenges to the treating physician. Contentious debate has continued regarding the most optimal surgical approach for these patients. A variety of transsacral and transvertebral techniques have been described in reported studies. ⋯ To the best of our knowledge, this is the first report to demonstrate the utility of the sacroiliac joint fusion cage using RBT in patients with HGS with successful clinical outcome. The RBT is safe, feasible, and effective in carefully selected patients.
