It remains unclear whether fusion for lumbar degenerative disc disease with positive discography produces better outcomes compared with nonoperative treatment. The aim of this study was to compare outcomes of patients with discography-concordant lumbar degenerative disc disease electing for fusion versus nonoperative treatment. ⋯ Comparison of long-term outcomes for patients with back pain and concordant discography did not demonstrate a significant difference in outcome measures of pain, health status, satisfaction, or disability based on whether the patient elected for fusion or nonoperative treatment.

This study was undertaken to evaluate de novo aneurysm formation in the long-term follow-up of patients with clipped aneurysms. ⋯ The risk of de novo aneurysm formation in patients with clipped aneurysms is significant in long-term follow-up. CT angiography can be used as a noninvasive method for detection of de novo aneurysms in these patients.

In the treatment of craniopharyngioma, complete surgical removal offers the best chance of cure and recurrence prevention. The basal interhemispheric approach involves problems with difficulty resecting tumors in the retrochiasmatic space located behind the optic chiasm and inability to resect, under direct view, tumors extending into the sella turcica. We report our approach via the sphenoid sinus devised to resolve these problems. ⋯ This approach allowed a working space to be secured even in cases with a narrow prechiasmatic space, allowing tumor freeing from the lower plane of the optic nerve and safe resection of the intrasellar tumor.

Distal posterior inferior cerebellar artery aneurysms: clinical features and outcome of 80 patients.
Aneurysms of the posterior inferior cerebellar artery (PICA) distal to its origin are rare. Beside their rarity, their treatment is challenged by a high proportion of fusiform aneurysms, torturous course of PICA, and often severe bleeding. Our aim is to represent the characteristics of these aneurysms and their treatment, as well as to analyze outcome. ⋯ Microsurgery is a feasible treatment for distal PICA aneurysms. Despite the challenge of often severe hemorrhage, wide-necked aneurysms, and some risk for laryngeal palsy, most patients surviving the initial stage return to normal life. Because of the greater number of rebleedings than for aneurysms at other locations, immediate treatment is crucial.

Clinical characteristics and management of hemangioblastomas of the spinal cord associated with von Hippel-Lindau syndrome have been extensively covered in the literature. This report aims to analyze the characteristics and surgical treatment results of sporadic spinal hemangioblastomas (SSHB). ⋯ The SSHBs occur most often in the upper spinal cord. Excellent surgical results and long-term outcome can be achieved using microsurgery alone with only rare recurrences.
