Review Case Reports
Flow-related aneurysm within glioblastoma: A case report and review of literature.
Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults, with a median survival of 13 months despite surgery and chemoradiation. GBMs are often hypervascular tumors caused by abnormal oversecretion of growth factors such as vascular endothelial growth factor. These angiogenic factors are hypothesized to promote increased blood flow and possibly secondary changes to arterial walls, thus facilitating the formation of flow-related aneurysms. ⋯ Hypervascular lesions, such as GBMs, may be associated with flow-related aneurysms on feeding arteries, but aneurysms within the gross tumor are unusual. Although rare, this finding needs to be recognized on preoperative imaging before tumor resection to prevent potentially catastrophic intraoperative complications.

Review Case Reports
Use of Intramedullary K-wire to Enhance Fibular Graft Placement in 4-level Thoracolumbar Corpectomy for Pott's Disease: Case Report and Review of Literature.
Reports of tuberculosis involving ≥4 contiguous spinal levels are rare. Surgery is often required in this population for neurological decompression and stabilization. These patients appear to be particularly predisposed to complications that include incomplete recovery of neurological function after decompression as well as post-treatment kyphosis. In settings with limited available instrumentation, reconstruction of the anterior column can be challenging. ⋯ At follow-up five-and-a-half months after the operation, the patient had recovered full strength and was ambulating without difficulty. Imaging at this time demonstrated stable restoration of alignment without graft dislodgement. Intramedullary fibular K-wire placement in this procedure helped to optimize anterior column reconstruction. The principles used in this report may prove beneficial to surgeons in developing countries who encounter pathology of this extent.
