The movements of a neurocysticercosis cyst within the ventricular cavity have been identified rarely. ⋯ Such an intraventricular migration of any kind of tumor has not been recorded in the literature.

We sought to report the operative techniques of the endoscopic supracerebellar transtentorial approach (ESTA) to the atrium of the lateral ventricle, especially focusing on the role of the endoscope and analyzing optically related issues. ⋯ ESTA is an alternative route to the atrium of the lateral ventricle. However, the collateral sulcus, which is highly relied on in neuronavigation, is illegible in the limited area. And the visual field deficit remains the primary challenge with this approach.

To present our experience with anterior transthoracic surgery for high-risk thoracic disc herniations (TDHs) using motor evoked potential monitoring (MEPm). ⋯ Maximal TDH AP diameter, SCO, SCC, (sub)total calcification, and ISC correlate with lower extremity MEP signal deterioration. In experienced hands, TMD with MEPm support is a safe, efficient procedure for high-risk TDHs.

The choice of appropriate treatment of discogenic low back pain (DLBP) frequently is difficult. This study sought to identify the clinical efficacy of percutaneous endoscopic lumbar annuloplasty and nucleoplasty (PELAN) to treat patients with DLBP and to investigate prognostic clinical or radiologic variables. ⋯ PELAN provided favorable outcomes in patients with DLBP who were refractory to conservative treatments. Flexion pain was good prognostic, and Modic change was a poor prognostic variable.

Although an asymptomatic spinal dural arteriovenous fistula (SDAVF) can sometimes be incidentally detected on magnetic resonance imaging (MRI), there are no previous reports showing the development of an SDAVF on MRI or magnetic resonance angiography (MRA). ⋯ This may be the first report in which serial MRA studies demonstrated the course of this condition, from the appearance of an SDAVF to the development of SAH. An abnormal vascular structure detected on MRA indicated abnormal enlargement of the perimedullary vein and the presence of a cervical SDAVF. A lower cervical SDAVF should be suspected if such an abnormal vascular structure is detected on MRA.
