Pituitary adenomas are mostly benign in character and are managed via a transsphenoidal approach in most cases. Crooke's cell adenoma (CCA) is a particular variant accounting for less than 1% of the pituitary adenomas. They have a distinctive histopathologic pattern and behavior. ⋯ CCA is recognized by its local aggressiveness and high recurrence rates. They tend to be locally invasive; however, posterior fossa invasion has not been reported to date. We aim to contribute to the arsenal of differential diagnosis of similar pituitary tumor cases.

Despite common gender disparities in authorship across the vast majority of specialties, the presence of a similar lack of equality in neurosurgery literature is not published yet. Therefore the authors examined the changes in representation of women among the first and senior (last) authors of original articles in high-impact neurosurgical journals between 2003 and 2018. ⋯ Although a rising trend in female authorship of neurosurgical literature has been going on through the last 2 decades, this advancement could not be regarded as satisfactory, as the gender gap in authorship is still excessive. Strikingly, female first authors had a tendency of coauthoring with female senior authors.

This paper explores the diagnostic value of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for the prognosis of glioma, and judges the relevant factors affecting the prognosis of glioma. This paper used a Cox proportional hazards model to retrospectively analyze clinical data of 81 patients with complete neuroglioma from the same neurosurgery medical team from January 2012 to November 2018, including DCE-MRI data. To determine the prognostic factors, P < 0.05 was used as the statistical standard, and the survival curve of statistically significant factors was drawn by Kaplan-Meier method. ⋯ Multivariate analysis and DCE-MRI data showed that age, tumor grade, preoperative KPS score, postoperative radiotherapy, and Ki-67 expression were prognostic factors for patients with glioma. The older the age, the higher the pathologic grade, the higher the Ki-67 expression level, and the lower the KPS score before surgery, the worse the prognosis. Postoperative radiotherapy and appropriate temozolomide chemotherapy will help improve the prognosis of patients with neuroglioma.
