Spinal epidural abscesses are difficult to diagnose and could have high morbidity and mortality if left untreated. If patients present with acute neurological deficits and evidence of a multilevel ventral spine abscess on neuroimaging, blood cultures should be taken and the abscess emergently evacuated in patients able to tolerate surgical interventions. ⋯ The patient's neurological deficits completely resolved, and he is intact a year after the operation. In selected patients with pan-spinal epidural abscesses associated with acute neurological deficits, a combination of an open approach and a catheter-based procedure in addition to an intraoperative monitoring option to ensure complete evacuation of the abscess and absence of septations in the anterior epidural space is a low-morbidity option in the armamentarium of the surgeon.

Surgical Management of a Patient With Thoracic Spinal Cord Herniation: Technical Case Report and Review.
Thoracic spinal cord herniation (TSCH) is rare and likely underdiagnosed. It is characterized by ventral herniation of the spinal cord through a dural defect, effacement of the anterior subarachnoid space, and increased posterior subarachnoid space. We present here a case of TSCH diagnosed and surgically treated at Barrow Neurological Institute, along with supplemental intraoperative video. ⋯ Anterior displacement of the thoracic spinal cord should elicit consideration of herniation to prevent misdiagnosis and inadequate surgery. Surgical cord release and enlargement of the dural defect are safe and associated with good clinical outcomes.

Case Reports
Brain Herniation After Endoscopic Transnasal Resection of Anterior Skull Base Malignancies.
Endoscopic endonasal approaches, when appropriate, allow a less invasive method to remove anterior skull base cancer than traditional external transfacial/craniofacial approaches. The resultant skull base defect can be significantly large, potentially extending from the posterior table of the frontal sinus to the tuberculum sellae in the sagittal plane, and from one lamina papyracea to the other in the coronal plane. However, frontal lobe herniation after such expanded endoscopic resection has been considered more of a theoretical than a practical occurrence. ⋯ Frontal lobe herniation must be considered as a possible, albeit rare, complication of expanded endoscopic anterior skull base resection. Preoperative investigations concerning the presence of obstructive sleep symptoms as well as proper identification of neuroimaging signs of intracranial hypertension are recommended for such cases.

The use of mechanical thrombectomy in the management of acute ischemic stroke is becoming increasingly popular. ⋯ The Solitaire device is safe and effective in achieving successful recanalization after acute ischemic stroke. Important factors to consider include age, NIHSS score, and location.

A piezo actuator-driven pulsed water jet (ADPJ) system is a novel surgical instrument that enables dissection of tissue without thermal damage. It can potentially resect intra-axial lesions while preserving neurological function. ⋯ The ADPJ provided a clear surgical field and enabled surgeons to dissect boundaries between lesions and surrounding brain and spinal cord gliotic tissue. The ADPJ system is a feasible option for cavernous malformation surgery, enabling successful tumor removal and preservation of neurological function.
