To determine preoperative factors contributing to postoperative hemorrhage after stereotactic brain biopsy (STB), clinical implications of postoperative hemorrhage, and the role of postoperative imaging in clinical management. ⋯ Postbiopsy hemorrhage was associated with higher risk of immediate and delayed postoperative deficit and seizure. Postoperative computed tomography should be used to determine whether STB patients can be discharged same day or admitted for observation; clinical evaluation should determine return to OR for evacuation.

Large or giant thrombosed intracranial aneurysms (LGTIAs) are highly associated with poor prognosis and remain a challenging disease to treat by either surgery or endovascular treatment (EVT). EVT is considered more difficult for complicated aneurysm like LGTIAs. To understand long-term clinical and angiographic outcomes of EVT for LGTIAs, we retrospectively analyzed our single-center data on multimodality EVT for patients with LGTIAs. ⋯ Multimodality EVT for LGTIAs was performed with similar clinical outcomes and better radiologic outcomes compared with previous reports. New innovative techniques and devices are expected to be helpful for long-term aneurysm occlusion.

Case Reports
A case of spontaneous regression of radiologically diagnosed epidermoid cyst originated from cerebellopontine angle.
Generally, asymptomatic epidermoid cysts (ECs) or ECs with minor symptoms controlled by medication are not treated further. Although epidermoid carcinomas are only sporadically reported, the possibility of malignant transformation of ECs is of concern. ⋯ The reduction of an EC is extremely rare. We report a case of spontaneous regression of an EC and consider similar previous cases.

Risk Factors Associated with Symptomatic Deep Vein Thrombosis Following Elective Spine Surgery: A Case-Control Study.
Few studies provide insight into risk factors (RFs) associated with postoperative deep vein thrombosis (DVT) following elective spinal surgery. DVTs are detrimental in this population because of the risk of pulmonary embolization or surgical site hemorrhage with treatment. ⋯ These results suggest that patients with a history of DVT undergoing elective spinal surgery are at higher risk of developing symptomatic DVT postoperatively resulting in significantly increased length of stay. Further studies on additional preoperative screening and medical optimization in elective spine surgery patients may help reduce the rate of symptomatic, postoperative DVT.

Sinorhizobium meliloti is a phytobacterium found in the root nodules of plants, where it is involved in fixing nitrogen for delivery to the roots in exchange for a photosynthate carbon source. There have been no reported cases of S. meliloti infection in humans. We conducted a retrospective review of clinical records and diagnostic tests. ⋯ S. meliloti is a phytopathogen that should not be easily disregarded as a contaminant when isolated from human sterile fluids or tissues. Aggressive management including removal of infected hardware, if present, is required to ensure resolution of infection. It emphasizes the importance of thorough history taking.
