Unusual and Rare Locations for Craniopharyngiomas: Clinical Significance and Review of the Literature.
This study discusses rare and unusual locations of primary craniopharyngiomas. ⋯ Craniopharyngiomas are most often located in the suprasellar region. Presentation in sites outside the parasellar region is rare. Among these ectopic sites, the cerebellopontine angle appears to be the most common location.

A 65-year-old female presented with progressive unilateral vision loss leading to blindness and features of central diabetes insipidus (DI) for 3 months' duration. Imaging showed a well-circumscribed, lobulated, rim-enhancing suprasellar lesion with inhomogeneous diffusion restriction. ⋯ At 5 months' follow-up, she had improvement of her diabetes insipidus but no visual improvement. This paper presents a case of suprasellar epidermoid with atypical imaging findings.

Review Case Reports
Endoscopic Removal of Suprasellar Colloid Cyst with Interpedincular and Prepontine Cisterns Extension.
Colloid cysts (CCs) are rarely found in the sellar-suprasellar region. Differential diagnosis of CCs is more challenging in this region because many other cystic lesions may locate or invade sellar or suprasellar structures. We present a large and unusual case of sellar-suprasellar CC with extension into the suprasellar, interpeduncular, and prepontine cisterns. This is the first case of sellar-suprasellar CC treated with an endoscopic transsphenoidal approach. ⋯ Although rarely found in this location, CC should be considered in the differential diagnosis in patients who present with a sellar-suprasellar cystic lesion. Additionally, sellar-suprasellar CC would be a good candidate for the endoscopic endonasal approach.

Meta Analysis
Adjuvant Radiosurgery versus Serial Surveillance following Subtotal Resection of Atypical Meningioma: A Systematic Analysis.
Atypical meningioma (AM) is an aggressive subtype of meningioma associated with a high recurrence rates (RR) following surgical resection. Recent studies have compared outcomes of various treatment strategies, but advantages of adjuvant radiosurgery (ARS) over serial surveillance (SS) following subtotal resection (STR) remain unclear. To further elucidate this issue, we systematically analyzed the current literature on AM and compared outcomes of ARS versus SS after STR. ⋯ The data presented here show significant differences in RR and 5-year PFS between ARS and SS, suggesting a potential benefit of ARS. As our understanding of the clinical outcomes of various treatment strategies for AM increases, we also move closer to integrating modalities, such as radiosurgery, into management guidelines.

Review Biography Historical Article
Ulf Fernstrom (1915-1985) and his Contributions to the Development of Artificial Disc Replacements: A Historical Vignette.
Artificial disc replacements, which serve the function of separating vertebrae to allow for proper spinal alignment, can help treat debilitating low back pain in patients who have failed other conservative methods of treatment. A Swedish surgeon, Ulf Fernström, was the pioneer of artificial disc replacement, and his contribution in the form of Fernström balls dramatically altered spinal surgery and technique by showing the proper technique and implant that should be used for areas requiring motion in many planes. ⋯ Of the wide range of implants on the market for the intervertebral disc space, all designs and applications of products stem from the initial discovery made by Fernström, thus making him a pioneer in disc replacement.
