Foot Drop after Ilio-Caval Vein Stenting: Radicular syndrome from stent misplacement in the spinal canal.
Endovascular procedures have become more and more prevalent in both general vascular and neurosurgical practices. Because these procedures rely on real-time bidimensional control through fluoroscopic guidance, they can be prone to spatial misplacement in the third dimension when not controlled in 2 different radiologic planes. ⋯ The complex venous anatomy of the lumbar region and lumbar epidural space is illustrated in this unique case. We believe this may serve both vascular surgeons and neurosurgeons in their daily practice.

To investigate whether tumor texture features derived from preoperative T1-weighted magnetic resonance imaging (MRI) are associated with overall survival (OS) of patients with non-wingless-type (WNT)/non-sonic hedgehog (SHH) medulloblastoma. ⋯ Texture analysis on T1-weighted contrast-enhanced MRI potentially serves as a prognostic predictor of survival for patients with non-WNT/non-SHH medulloblastoma.

Cerebellar ectopy is a rare finding, with few cases previously reported. Intraventricular localized cerebellar ectopy was described in only 1 case within the fourth ventricle. ⋯ We describe, for the first time to our knowledge, the case of a child with ectopic cerebellar tissue harboring the supratentorial ventricular system. Plausible etiologic mechanism consists in the herniation of the cerebellar germinal tissue into the ventricular system through the ependyma, allowing cell migration to the supratentorial compartment, followed by maturation into the normal cerebellum.

This case Video 1 demonstrates a microsurgical technique for trapping and excision of 2 ruptured mycotic aneurysms. The patient was a 64-year-old man with severe mitral regurgitation and valvular vegetations suggestive of endocarditis. On examination, the patient presented with speech difficulty. ⋯ Postoperatively, the patient remained symmetric in his motor strength and had improved speech deficits, indicative of an uneventful recovery. The patient was cleared for full anticoagulation and valve replacement on postoperative day 10. The patient underwent intravenous antibiotic therapy with ceftriaxone before undergoing mitral valve replacement by cardiac surgery.
