Preoperative patient optimization is increasingly recognized as key to good surgical outcomes. Preoperative hyponatremia is a modifiable risk factor linked to poorer postoperative outcomes in other surgical fields. We provide the first investigation of the association of preoperative hyponatremia with morbidity and mortality in patients undergoing cervical spine surgery. ⋯ Using the National Surgical Quality Improvement Program database, hyponatremia is observed in approximately 1 in every 20 patients undergoing cervical spine fusion. More importantly, it is a predictor of mortality, major morbidity, and prolonged hospitalization. From a systems-level perspective, preoperative hyponatremia may therefore represent a point of intervention for preoperative patient optimization.

Case Reports
Spinal cord compression caused by fibroblastic reticular cell tumour (FRCT) originating from thoracic spine.
The authors present the first reported case of a fibroblastic reticular cell tumor (FRCT) presenting with spinal cord compression. FRCTs are the rarest subset of dendritic cell tumors, a specific group of hematologic malignancies. FRCTs reportedly behave similar to low-grade sarcomas as opposed to malignant tumors. ⋯ Although rare, we report the first case of FRCT originating in the spine causing spinal cord compression. The clinical presentation of the case, histologic features of FRCT, and the treatment options are reviewed.

Case Reports
Severe intracranial hypotension after a middle fossa approach for spontaneous otogenic pneumocephalus. Case report.
Spontaneous otogenic pneumocephalus is a rare condition caused by erosion of the tegmen tympani with subsequent entrance of air into the intracranial space. Its pathogenesis is thought to involve a previous state of intracranial hypotension, which pulls air into the intracranial cavity. The surgical management involves obliteration of the tegmen defect via a mastoidectomy or a middle fossa approach. Lumbar drainage has been used safely as an adjunct to middle fossa approaches so as to provide brain relaxation and decrease the incidence of postoperative cerebrospinal fluid leaks. ⋯ Intraoperative lumbar drainage during a middle fossa approach for spontaneous otogenic pneumocephalus may dramatically aggravate a state of preexisting intracranial hypotension and lead to transtentorial herniation.

Case Reports
First Report of Extraspinal Lead Migration along a Thoracic Spinal Nerve after Spinal Cord Stimulation.
Spinal cord stimulation for failed back surgery syndrome and chronic pain is a well-established treatment regimen today. Lead migration is the most common complication; mainly epidural caudal more than cranial electrode migration from the primary position is described repeatedly throughout the literature. ⋯ Lead migration remains a challenge in spinal cord stimulation regardless of the fixation method. Rare unusual migration patterns in addition to simple caudal or cranial migration might pose a challenge for revision surgery and thus might reduce overall treatment efficacy.

Mechanical thrombectomy has become the standard treatment for acute ischemic stroke caused by large vessel occlusion; however, refractory occlusions still occur despite various thrombectomy procedures. The double stent retriever (SR) technique, which employs 2 SRs simultaneously at the occlusion, can be useful for such refractory occlusions. ⋯ Our radiographic findings suggested that adding a second SR facilitates the device-clot interaction at the occlusion site. The double SR technique may be an easy-to-perform thrombectomy technique to improve clot-capturing ability for the management of refractory acute cerebral artery occlusions.
