Review Case Reports
Primary Intradural Extramedullary Sporadic Spinal Hemangioblastomas: Case Report and Systematic Review.
Hemangioblastomas are benign vascular neoplasms of the central nervous system that may occur sporadically or in association with Von Hippel-Lindau disease. A minority of these lesions can occur in the spine, mostly as intramedullary masses. The authors present a rare case of primary sporadic spinal hemangioblastoma occurring as an intradural extramedullary (IDEM) lesion. Diagnostic workup and surgical management of the patient are described. ⋯ Primary IDEM hemangioblastomas are a rare entity. Differential diagnosis includes other IDEM lesions, such as schwannomas, meningiomas, or some vascular malformations. Resection of these sporadic tumors can be safely performed and result in improvement of neurologic deficits associated with mass effect from the tumor with low likelihood of recurrence.

The effect of genetic factors on presentation and outcomes of moyamoya disease (MMD) is unclear. We aimed to examine differences in presentation of MMD by genetic variant, delineate the influence of genetic factors on outcomes, and characterize the applicability of genetic testing to management. ⋯ Genetic factors correlate with MMD presentation including age of onset, severity, and symptoms, and angiographic and clinical outcomes after surgery. Incorporation of genetic testing panels into practice may allow for risk stratification, management, and follow-up of children and adults with MMD. However, future studies are necessary to validate the usefulness of genetic testing for MMD before this situation occurs.

Multicenter Study Comparative Study
Comparison of treatment modalities in post-irradiation carotid blowout syndrome: a multi-center retrospective review.
Carotid blowout syndrome (CBS) is not uncommon in our locality, where head and neck cancers, especially nasopharyngeal carcinoma, are prevalent. Traditionally, CBS has resulted in high morbidity and mortality. The treatment paradigm has evolved from open surgery to endovascular interventions, and each treatment modality has its merits and drawbacks. In the present study, we investigated the outcomes of different treatment modalities for postirradiation CBS. ⋯ Our results have shown that endovascular trapping is the first-line treatment of CBS. For patients with contraindications to endovascular trapping, the flow diverter is an alternative. For patients who have undergone flow diversion alone, definitive treatment such as bypass surgery might be indicated for selected patients to minimize the risk of rebleeding. After endovascular trapping, surgical bypass might be considered for selected patients with a higher risk of stroke.

Few studies have evaluated the cost burden borne by neurosurgical patients in the developing world and their potential implications for efficient and effective delivery of care. This study aims to assess the cost associated with obtaining pediatric neurosurgical care in a hospital in Kaduna. ⋯ The mean cost of pediatric neurosurgical procedures in our setting is $895.99, which is 40.18% of our gross domestic product per capita. The main drivers of cost are the cost of operation, investigations, and intensive care unit length of stay.

We sought to examine the conservative treatment of symptomatic spinal cavernomas and evaluate the efficacy and safety of surgical management of spinal cord cavernous malformations. ⋯ Patients who have experienced a hemorrhagic episode should consider surgical intervention, which decreases the risk of recurrent hemorrhage and further neurologic deterioration. In addition, surgical decompression obtained by resection of the hemorrhage and cavernoma seems to lead to slight neurologic improvement in some patients. In nonhemorrhagic cavernomas, conservative treatment might be optimal due to surgery-related morbidity risks.
