Although rarely, the usually benign, supratentorial, grade II astrocytic tumour pleomorphic xanthoastrocytoma (PXA) may arise from the cerebellum. A review of the published cases of these PXAs is made including the author's own case of a 40 years-old man with a right cerebellopontine angle tumour, which recurred after a gross total resection. The major clinical and histopathological features of cerebellar PXAs are discussed, and factors playing a role in their biological behaviour, like post-surgical medical treatment, genetics and extent of leptomeningeal seeding are stressed.

Minimally invasive parafascicular surgery (MIPS) with the use of tubular retractors achieve a safe resection in deep seated tumours. Diffusion changes noted on postoperative imaging; the significance and clinical correlation of this remains poorly understood. Single centre retrospective cohort study of neuro-oncology patients undergoing MIPS.

Background: Glioblastoma (GBM) is a lethal brain tumor characterized by the glioma stem cell (GSC) niche. The V-ATPase proton pump has been described as a crucial factor in sustaining GSC viability and tumorigenicity. Here we studied how patients-derived GSCs rely on V-ATPase activity to sustain mitochondrial bioenergetics and cell growth.

The prevalent tumor-supporting glioblastoma-associated macrophages (GAMs) promote glioblastoma multiforme (GBM) progression and resistance to multiple therapies. Repolarizing GAMs from tumor-supporting to tumor-inhibiting phenotype may troubleshoot. However, sufficient accumulation of drugs at the GBM site is restricted by blood-brain barrier (BBB).

Limited advancements in managing malignant brain tumors have resulted in poor prognoses for glioblastoma (GBM) patients. Standard treatment involves surgery, radiotherapy, and chemotherapy, which lack specificity and damage healthy brain tissue. Boron-containing compounds, such as boric acid (BA), exhibit diverse biological effects, including anticancer properties.

Objective: Communicating hydrocephalus (CH) is an uncommon complication that can affect patients with glioblastoma (GBM). Due to its clinical and radiological findings, it presents as a chronic hydrocephalus. The mechanisms underlying its occurrence and impact on the prognosis of the disease are poorly known, but some studies have suggested that shunting can have a positive impact on the quality of life of these patients.
