Multicenter Study
Surgical Clipping of Very Small Unruptured Intracranial Aneurysms: A Multicenter International Study.
Treatment of very small unruptured intracranial aneurysms (VSUIAs, defined as ≤3 mm) can be indicated in selected circumstances. The feasibility and outcomes of endovascular therapy for VSUIAs have been recently published; however, the efficacy and complication rate of surgical clipping has not been reported in any large series to date. ⋯ VSUIA clipping is highly effective and is associated with a low morbidity rate. For VSUIAs selected for treatment, our data support surgical clipping as the modality of choice.

Review Case Reports
A Mobile Schwannoma of the Cervical Spinal Cord: A Case Report and Review of the Literature.
Mobile schwannomas have been reported in the lumbar spine and occasionally in the thoracic spine. However, to the best of our knowledge, this is the first known report of a cervical mobile schwannoma. Mobile schwannomas require careful preoperative and intraoperative evaluation of their localization because tumor mobility may result in surgery at the wrong level. ⋯ We observed an extremely rare case of a mobile schwannoma of the cervical spine. Unusually dilated subarachnoid space adjacent to the tumor can be a diagnostic sign of tumor mobility, regardless of vertebral level. Repeated MRI studies are useful to preoperatively confirm tumor mobility. Intraoperative ultrasonography is valuable for the real-time localization of such mobile tumors to avoid potentially performing surgery at the wrong vertebral level.
