Parasagittal meningiomas arise from the arachnoid cells of the angle formed between the superior sagittal sinus (SSS) and the brain convexity. In this retrospective study, we focused on factors that predict early recurrence and recurrence times. ⋯ Male sex is an independent risk factor for recurrence that, associated with other factors such tumor size and histologic type, explains 74.5% of all cases in a binary regression model.

Cervical transforaminal epidural steroid injection (TFESI) is considered one of the most effective treatments for radicular pain induced by cervical foraminal stenosis. ⋯ The treatment outcome of cervical TFESI did not different according to the severity of cervical foraminal stenosis. However, on the basis of our results, we suggest that TFESI can be a beneficial clinical option for managing radicular pain due to cervical foraminal stenosis.

The transnasal approach to lesions involving the craniovertebral junction represents a technical challenge because of limited inferior exposure. The endoscopic transseptal approach (EtsA) with posterior nasal spine (PNS) removal is described. This technique can create a wide exposure of the craniovertebral junction, thereby increasing the caudal exposure. ⋯ Endoscopic endonasal approaches to the craniovertebral junction are increasing, but the downward extension on the anterior cervical spine represents a limit. Therefore, many surgeons prefer transoral or transcervical approaches. The EtsA with PNS removal allows for a more caudal exposure than the standard paraseptal approach, with reduced nasal trauma.

Spondyloptosis is grade V on the Meyerding classification. Traumatic spondyloptosis can occur throughout the spinal column, particularly at junctional levels, and finding an ideal surgical strategy to address it remains a challenge for spinal surgeons. The sacrum is considered a united bone in adults, and sacral intersegmental spondyloptosis is extremely rare. ⋯ This case demonstrates that similar distal sacral pathologies may be managed conservatively when there is no associated neurologic deficit, and the osteodiskoligamentous integrity of the lumbosacropelvic unit remains intact. Our report plus the very few published papers in the literature illustrate the natural history of uncomplicated traumatic spondyloptosis and support the role of in situ fusion and instrumentation as a reliable alternative to circumferential fusion in patients who cannot tolerate staged or prolonged operations.
