Biological and clinical impact of hemangioblastoma-associated peritumoral cysts in von Hippel-Lindau disease.
Peritumoral cysts are frequently associated with CNS hemangioblastomas and often underlie neurological morbidity and mortality. To determine their natural history and clinical impact, the authors prospectively analyzed hemangioblastoma-associated peritumoral cysts in patients with von Hippel-Lindau (VHL) disease. ⋯ Peritumoral cysts frequently underlie symptom formation that requires surgical intervention in patients with VHL disease. Development of new cysts was associated with a larger number of cysts at study enrollment and younger age. Total peritumoral cyst burden was associated with germline partial deletion of the VHL gene.

Quality of survival the 1st year with glioblastoma: a longitudinal study of patient-reported quality of life.
By exploring longitudinal patient-reported health-related quality of life (HRQoL), the authors sought to assess the quality of survival for patients in the 1st year after diagnosis of glioblastoma. ⋯ The results indicate that progression-free survival is not only a surrogate marker for survival, but also for quality of survival. Quality of survival seems to be associated with GTR, which adds further support for opting for extensive resections in glioblastoma patients with good preoperative functional levels.

A combinatorial radiographic phenotype may stratify patient survival and be associated with invasion and proliferation characteristics in glioblastoma.
Individual MRI characteristics (e.g., volume) are routinely used to identify survival-associated phenotypes for glioblastoma (GBM). This study investigated whether combinations of MRI features can also stratify survival. Furthermore, the molecular differences between phenotype-induced groups were investigated. ⋯ A 3-way combination of MRI phenotypes may be capable of stratifying survival in GBM. Examination of molecular processes associated with groups created by this combinatorial phenotype suggests the role of biological processes associated with growth and invasion characteristics.

Safety, efficacy, and life satisfaction following epilepsy surgery in patients aged 60 years and older.
Despite its potential to offer seizure freedom, resective epilepsy surgery (RES) is seldom performed in patients 60 years of age or older. Demonstrating successful outcomes including an improved quality of life may raise awareness about the advantages of referring this underrepresented population for specialized evaluation. Accordingly, the authors investigated outcomes and life fulfillment in patients with an age ≥ 60 years who had undergone RES. ⋯ Resective epilepsy surgery is safe and effective in patients with an age ≥ 60 years. Over 90% had a good surgical outcome, with 50% becoming completely seizure free despite 1 or more medical comorbidities in the majority. The study data indicated that an advancing age should not negatively influence consideration for RES.

Case ReportsEndonasal endoscopic transsphenoidal chiasmapexy using a clival cranial base cranioplasty for visual loss from massive empty sella following macroprolactinoma treatment with bromocriptine: case report.
Visual deterioration after dopamine-agonist treatment of prolactinomas associated with empty sella syndrome and secondary optic apparatus traction is a rare event. Chiasmapexy has been described as a viable treatment option, although few cases exist in the literature. Here, a novel endonasal endoscopic approach to chiasmapexy is described and its efficacy is demonstrated in a case report. ⋯ Postoperative imaging demonstrated successful anatomical elevation of the optic apparatus, and the patient showed functional improvement in the visual field at 3 months postoperatively. Although rare, massive empty sellar and chiasmal descent from macroadenoma treatment can result in progressive visual loss. Here, a novel technique of endonasal endoscopic extradural cranioplasty aided by lumbar drainage is reported, which appears to be an effective technique for stabilizing and possibly reversing anatomical and visual deterioration.
