Gangliogliomas (GGs) are extremely rare benign neoplasms frequently located within the temporal lobe that usually present with seizures. GGs growing predominantly within the ventricular system (VGGs) are even more infrequent, so definite conclusions concerning their diagnosis and therapeutic management are lacking. ⋯ Despite their low incidence, a diagnosis of VGGs should be considered in young male adults who progressively develop intracranial hypertension, caused by a ventricular mass showing signs of cystic degeneration and calcification. Maximal and safe surgical resection represents the gold standard for the treatment of symptomatic VGGs, although total removal is frequently precluded by difficulties in defining appropriate tumor boundaries. Adjuvant radiotherapy should be considered if an incomplete resection was carried out, especially in World Health Organization grade III neoplasms.

Extra-axial fluid collections (EACs) frequently develop after decompressive craniectomy. Management of EACs remains poorly understood, and information on how to predict their clinical course is inadequate. We aimed to better characterize EACs, understand predictors of their resolution, and delineate the best treatment paradigm for patients. ⋯ Our analyses reveal 2 clinically relevant phenotypes of EAC: complicated and uncomplicated. Our proposed treatment algorithm involves replacing the bone flap as soon as it is safe to do so and draining refractory EACs aggressively. Further studies to assess long-term clinical outcomes of EACs are warranted.

Surgical or endovascular management of middle cerebral artery aneurysms: A randomized comparison.
There are few randomized data comparing clipping and coiling for middle cerebral artery (MCA) aneurysms. We analyzed results from patients with MCA aneurysms enrolled in the CURES (Collaborative UnRuptured Endovascular vs. Surgery) and ISAT-2 (International Subarachnoid Aneurysm Trial II) randomized trials. ⋯ Randomized data from 2 trials show that better efficacy may be obtained with surgical management of patients with MCA aneurysms.

Dominique Anel, John Hunter and the eponymous Hunterian Ligation of Aneurysms: Conception to current practice.
The contributions of both Dominique Anel and John Hunter in the development of the eponymous Hunterian ligation of aneurysms are presented. John Hunter, the "father of scientific surgery" lent his name to the eponymous practice of applying ligatures to aneurysmal dilatation of arteries. However, evidence suggests that the operation might antedate him by decades. ⋯ Hunterian ligation was used routinely before endoaneurysmorrhaphy, after which its popularity declined. Hunterian ligation has been superseded by development of surgical clips and endovascular techniques for intracranial aneurysms. However, the technique is still described occasionally in vascular and neurosurgical literature in the context of treating large aneurysms not amenable to traditional treatment modalities.

Effect of Toremifene on Endometrium and Neurocognitive Function in Patients with Breast Cancer Based on Resting State Functional MRI.
In this study, the characteristics of hemodynamic changes with use of toremifene before and after neoadjuvant chemotherapy in breast cancer treatment were analyzed using resting-state functional magnetic resonance imaging. Also, the effect of toremifene on the quality of life of patients with advanced breast cancer was analyzed. The study population comprised 100 patients who received endocrine therapy after breast cancer surgery in our hospital from January 2016 to January 2019. ⋯ The mean values of the early enhancement parameters Efirst, Vfirst, Ee, and Ve before chemotherapy were greater than in the residual lesions after chemotherapy (P < 0.5). The semiquantitative study of resting brain function before and after breast cancer neoadjuvant chemotherapy showed that the hemodynamics of the residual lesions were significantly reduced, and the blood flow rate was significantly reduced. Compared with the clinical effect of tamoxifen in the treatment of breast cancer after surgery, tamoxifen combined with toremifene has more advantages in improving quality of life, improving progesterone levels, and reducing estrogen levels, and it has no detrimental effects on the endometrium.
