Sex has been known to significantly affect postoperative complications and length of stay after elective anterior cervical fusions. Current evidence on lumbar spine surgery is limited. ⋯ Contrary to literature on cervical fusions, we found that female sex was independently tied to an increased risk of adverse outcomes after elective posterior lumbar fusion. The results from the study suggest that women may benefit from close surveillance during the postoperative period to minimize risk of complications and subsequent resource utilization in this group.

The effect of statins and diabetes on angiographic and clinical outcomes in aneurysms treated with pipelines has not been adequately reported. Our aim is to assess the effect of concurrent statin medications and diabetes mellitus (DM) on aneurysm occlusion status and outcomes in patients treated with the pipeline embolization device. ⋯ Our analysis did not identify a statistically significant association between statin therapy or DM and higher occlusion rates or better outcomes after pipeline embolization. Diabetic patients may have a theoretic risk of significant in-stent stenosis.

Pituitary apoplexy (PA) is a life-threatening syndrome. The usage of a dopamine agonist, such as bromocriptine or cabergoline, is considered a predisposing factor for PA, which commonly occurs 1.5 years within commencement. ⋯ PA related to dopamine agonist therapy can occur in cases of elevated bleeding tendency, even in long-term users, suggesting that attention should be paid in the administration of a dopamine agonist in the patient experiencing thrombocytopenia. Surgical intervention should be performed after the preoperative platelet number and adequate response to transfusion are confirmed, and the aggressive removal of prolactinoma in the cavernous sinus should be avoided to reduce the risk of hemorrhagic complications.

Rosai-Dorfman disease (RDD) is a benign, self-limiting, and nonneoplastic histiocytic proliferative disorder with a poorly defined pathogenesis. Central nervous system involvement is extremely rare, particularly cases with multiple intracranial masses. There is no consensus on optimal treatment and management of RDD. ⋯ RDD with multiple isolated intracranial foci is rare but should be considered in the differential diagnosis when multiple meningiomas are suspected in children and adults. Preoperative diagnosis is challenging, and definitive diagnosis requires immunohistochemical examination. Surgical resection is the most effective therapy for rapid relief of symptoms.

A reliable, noninvasive method to differentiate high-grade glioma (HGG) and intracranial metastasis (IM) has remained elusive. The aim of this study was to differentiate between HGG and IM using tumoral and peritumoral diffusion tensor imaging characteristics. ⋯ Tract count and tract density were significantly different in tumoral and peritumoral regions between HGG and IM. Differences in microenvironmental interactions between the tumor types may cause these tract differences.
