Spinal tumors are referred for preoperative embolization to minimize intraoperative blood loss and facilitate surgical resection. ⋯ The rapid evolution of neurointervention and spinal tumor embolization has made scientific inquiry and definitive conclusion on the safety and efficacy of the practice difficult. The data supporting the procedure are fragmented and largely based on a multitude of retrospective studies that use varying techniques. Review of the available literature support embolization of spinal tumors as a safe and efficacious treatment adjunct before surgery.

Gangliogliomas (GG) are benign, primary neoplasms most commonly noted in young adults. Intraventricular location is rare. We report a case of a multicentric intraventricular GG posing diagnostic and therapeutic challenges and in addition provide a detailed literature review of intraventricular GG. ⋯ Intraventricular GG are rare tumors. Complete surgical excision achieves excellent results. The role of adjuvant therapy is controversial.

Review Case Reports
Orbitofrontal cholesterol granuloma: Four case reports and a systematic review of the English literature.
Primary orbitofrontal cholesterol granuloma (OFCG) is rare. We present 4 cases of OFCG and a systematic literature review to examine patient characteristics, presentation, treatment, and outcome. ⋯ Thorough removal of the lesion with curettage of the boney cavity is recommended for OFCG. Recurrence following complete removal of OFCG is rare.

To review and synthesize the clinical literature regarding risks and benefits of omentum transplantation and transposition surgery in patients with ischemic stroke of other etiology (non-MMD) and Moyamoya disease (MMD), and to evaluate the evidence for biological underpinnings of the presumed physiologic effects of omentum transplantation and transposition on vascularization of brain parenchyma. ⋯ Surgical revascularization using omental tissue has shown good success rates, particularly for recurrent transient ischemic attacks and prevention of further strokes and should be considered as treatment option for selected patients. Experimental data on the physiologic basis for postoperative improvement delivered convincing evidence for its arteriogenic potential and recent developments in omental stem cell research suggest a role in recovery from long-standing neurological deficits.

Case Reports Comparative Study
Delayed Hemorrhage Following Treatment of Brain Arteriovenous Malformations (AVMs).
The risk of delayed hemorrhage occurring greater than 2 years after treatment in brain arteriovenous malformations (AVMs) rarely is reported. In this study, we compare the risk of delayed hemorrhage across different treatment modalities. ⋯ This study is the first to compare the risk of delayed hemorrhage across different treatment modalities. Surgical resection is associated with the lowest risk for delayed hemorrhage compared with other treatment modalities. Patients with partially embolized AVMs should seek timely definitive treatment to decrease the risk of delayed hemorrhage.
