Angiosarcomas are rare malignant tumors of endothelial origin. Nearly one half of all angiosarcomas occur in the head and neck. Temporal bone angiosarcomas are extremely uncommon. We present a case of temporal bone angiosarcoma and a review of the relevant data. ⋯ Angiosarcoma of the temporal bone is extremely uncommon. In the present case report, we explored a relationship between trauma and angiosarcoma of the temporal bone. We reviewed the reported data regarding the pathogenesis, diagnosis, treatment, radiologic findings, and histologic characteristics of angiosarcoma of the temporal bone.

Vitamin D deficiency is a well-known cause of postoperative complications in patients undergoing orthopedic surgery. Orthopedic complications seen in vitamin D deficiency include nonunion, pseudarthrosis, and hardware failure. We seek to investigate the relationship between vitamin D deficiency and outcomes after lumbar spinal fusions. ⋯ Both preoperative and postoperative vitamin D levels were not significantly associated with an increased or decreased risk of pseudarthrosis, revision surgery, hardware failure, or 1-year VAS pain score after lumbar spine fusion surgery.

To investigate the effect of end plate morphology on cage subsidence and to compare the surgical outcomes among patients with different vertebral end plate morphologies. ⋯ Morphology of the end plate plays an important role in the development of cage subsidence after TLIF surgery. Fused segments with irregular end plates are prone to cage subsidence. Although cage subsidence does not affect short-term clinical outcomes, measures should be taken to prevent cage subsidence-related loss of SL and total LL.

The need for neurosurgical care across the globe remains a public health issue. The creation of sustainable neurological surgery departments and training programs will be indispensable in alleviating the burden of neurological disease in low to middle income countries (LMICs). ⋯ A sustainable neurosurgery practice and training program is possible in a LMIC. Training neurosurgeons in developing regions of LMICs is a sustainable method to decrease the morbidity and mortality of neurological diseases and prevent the misdistribution of physicians in a country. We encourage adaptation of sustainable neurological surgery practices in similar regions across the world to increase access to necessary neurosurgical care.

Middle cerebral artery (MCA) aneurysms have continued to be primarily managed microsurgically. In cases of complex MCA aneurysms, revascularization could facilitate effective aneurysm treatment. The MCA candelabra provides excellent candidates for in situ side-to-side bypass. In the present case series, we have described applications of MCA in situ side-to-side bypass for the management of complex MCA aneurysms, along with a review of the pertinent data. ⋯ Our experience with MCA side-to-side in situ bypass has demonstrated its safety and utility in complex MCA aneurysm management. The favorable anatomy of the MCA branches allows for minimally invasive revascularization and clipping that can potentially reduce the hospitalization time and incidence of perioperative morbidity.
