To analyze the association between basilar invagination (BI) and stenosis in the hypoglossal canal (HC). ⋯ Patients with BI of type B presented the narrowing of HC when compared with control participants.

The artery of Wollschlaeger and Wollschlaeger is a tentorial branch of the superior cerebellar artery that is usually not visualized on conventional cerebral angiography, unless it is pathologically enlarged. It can be recruited as part of the blood supply to tentorial dural arteriovenous fistulas (AVFs), although this occurs infrequently. ⋯ The anatomic discrepancy between the symptomatic spinal cord lesion and the etiologic intracranial fistula frequently results in delayed care in cases of myelopathy due to intracranial dural AVFs. Familiarity with these disorders and of their pathophysiologic mechanisms is important to avoid unnecessary diagnostic delays.

An epidural nerve block injection is the most common modality of treatment for control of low backache associated with radiating pain. Epidural catheter injections are also widely used by pain physicians to control cancer pain. Epidural catheters could be associated with procedure-related complications, such as epidural hematoma, epidural abscess, and post-dural puncture headache, and rare complications, such as shearing or breakage of the catheter tip. In this report, we describe the full-endoscopic removal of a sheared epidural catheter fragment. ⋯ Interlaminar full-endoscopic procedure could be used for the removal of the retained epidural catheter as a practical option.

Diffuse large B-cell lymphoma (DLBCL) is the most commonly diagnosed primary non-Hodgkin lymphoma of the spine and can induce spinal compression. Reports of lymphoma arising in bone adjacent to metallic prostheses are increasing. However, to our knowledge, DLBCL arising from a scar after lumbar fusion surgery has not been reported previously. ⋯ This case highlights the need to consider malignancy in the differential diagnosis and carefully examine surgical specimens in revision surgery. Further understanding of the role of metal implants in the development of lymphoma is required.

A plethora of cutting-edge neuroimaging analyses have been developed and published, yet they have not hitherto been realized as improvements in neurosurgical outcomes. In this paper we propose a novel interface between neuroimaging and neurosurgery for aiding translational research. Our objective is to create a method for applying advanced neuroimaging and network analysis findings to neurosurgery and illustrate its application through the presentation of 2 detailed case vignettes. ⋯ The described interface has widespread applications for translational research including preoperative planning, neurosurgical training, and detailed patient counseling. A protocol for assessing its effectiveness and safety is proposed. Finally, recommendations for effective translation of findings from neuroimaging to neurosurgery are discussed, with the aim of making clinically meaningful improvements to neurosurgical practice.
