Spinal trauma is common in polytrauma; spinal cord injury (SCI) is present in a subset of these patients. Penetrating SCI has been studied in the military; however, civilian SCI is less studied. Civilian injury pathophysiology varies given the generally lower velocity of the projectiles. We sought to investigate civilian penetrating SCI in the United States. ⋯ Penetrating SCI represents 5.5% of all SCI patients. Men, blacks, and Hispanics are disproportionally more affected by penetrating SCI. Patients with penetrating SCI have fewer surgical interventions, but their overall length of stay and hospital costs are greater compared with nonpenetrating SCI.

Case Reports
Intraventricular tension pneumocephalus after subarachnoid haemorrhage and removal of an external ventricular drain.
Pneumocephalus is defined as an accumulation of air or gas in the intracranial space. It is a common complication after skull surgery or craniofacial trauma, sometimes also caused by gas-producing organisms in the context of an infection, and reported with cerebrospinal fluid draining procedures. ⋯ The acute management included therapy with normobaric oxygen. Despite the large volume of trapped air and its diffuse distribution inside the skull and spine, therapy with 100% normobaric oxygen appears to be safe and efficient for a rapid improvement of the patient's symptoms and the neuroradiological imaging.

We present an unusual but possible complication after ETV for the treatment of acute hydrocephalus due to malfunction of a previously implanted V-P shunt. ⋯ One should consider such occurrence in cases of early ETV failure when a ventricular catheter is left in situ, even though temporarily.

Craniovertebral junction (CVJ) hydatid disease, although rare, forms an important differential diagnosis of CVJ bony pathologies, especially in endemic areas due to the sheer volume of cases presented there. The authors report a rare case of CVJ hydatid disease mimicking a bony expansile tumor on imaging. ⋯ The authors conclude that in tropical regions, hydatid disease of the cervical spine should be considered in the differential diagnosis of patients presenting with high cervical compressive myelopathy, especially when associated with fever. Spinal hydatosis may mimic a bony lesion on imaging and should be kept in mind, as in addition to routine decompression, use of scolicidal agents and intact removal of cysts have a significant effect on reducing the recurrence rate and improving the outcome.

The Use of Augmented Reality to Improve Safety of Anterior Petrosectomy: 2-Dimensional Operative Video.
An anterior petrosectomy (AP) provides access to the upper petroclival region, but approach-related complications include seizures and temporal lobe hematomas.1 Moreover, the floor of the middle fossa contains multiple critical neurovascular structures, and drilling Kawase's quadrilateral must be performed carefully to avoid iatrogenic injury. In particular, the cochlea, carotid artery, and the contents of the internal acoustic canal are vulnerable because there are no locational cues to help the surgeon define their borders.2-4 In this video, we demonstrate the use of an augmented reality (AR) to protect critical structures during drilling of an AP. The illustrative case involves a 70-year-old woman with difficulty walking caused by a petrotentorial meningioma. ⋯ The AP in surgery mimicked the one practiced during rehearsal and provided exposure to our patient's tumor. After surgery, the patient awoke without injury to her hearing, balance, or facial movements. By providing visual locational cues to the surgeon, we believe that AR improves the safety to the critical neurovascular structures during AP.
