Multiple primary brain tumors are commonly observed in patients with a history of brain radiation therapy or neurofibromatosis. The concomitant presence of 2 different types of brain tumors in a single location or chamber is a very rare clinical presentation in the absence of such a predisposing factor. The authors report on the case of a 16-year-old boy presenting with different types of brain tumors in 2 ventricular chambers concomitantly. This boy had a medium-sized colloid cyst of the third ventricle and a large fibrillary astrocytoma fungating from the brainstem into the floor of the fourth ventricle. The lesions were successfully excised in 2 separate surgeries. Radiotherapy was used as the adjuvant mode of therapy. There has been no sign of tumor recurrence after 16 months of follow-up. Clinical awareness and recognition of such a combination of tumors is important because they will dictate special treatment strategies depending on the individual biological aggressiveness of each tumor.

Introduction: Craniopharyngiomas are challenging benign tumors arising from Rathke's pouch remnants, often requiring multidisciplinary management due to their proximity to critical neurovascular structures. This meta-analysis systematically compares conventional radiation therapy (RT) and stereotactic radiosurgery (RS) in treating residual or recurrent craniopharyngiomas.
Method: A comprehensive literature search identified 44 studies, including 46 reports, meeting inclusion criteria such as progression-free survival (PFS) and post-radiotherapy complications.

Background: Traumatic brain injury (TBI) can generally be divided into focal damage and diffuse damage, and neonate Hypoxia-Ischemia Brain Damage (nHIBD) is one of the causes of diffuse damage. Patients with nHIBD are at an increased risk of developing Alzheimer's disease (AD). However, the shared pathogenesis of patients affected with both neurological disorders has not been fully elucidated.

In neuro-oncology, MR imaging is crucial for obtaining detailed brain images to identify neoplasms, plan treatment, guide surgical intervention, and monitor the tumor's response. Recent AI advances in neuroimaging have promising applications in neuro-oncology, including guiding clinical decisions and improving patient management. However, the lack of clarity on how AI arrives at predictions has hindered its clinical translation.

Radiation therapy (RT) is a prevalent cancer treatment; however, its therapeutic outcomes are frequently impeded by tumor radioresistance, largely attributed to metabolic reprogramming characterized by increased fatty acid uptake and oxidation. To overcome this limitation, we developed polyphenol-metal coordination polymer (PPWQ), a novel nanoradiotherapy sensitizer specifically designed to regulate fatty acid metabolism and improve RT efficacy. These nanoparticles (NPs) utilize a metal-phenolic network (MPN) to integrate tungsten ions (W), quercetin (QR), and a PD-L1-blocking peptide within a PEG-polyphenol scaffold.

Objective: This study aims to elucidate the primary signaling communication among papillary craniopharyngioma (PCP) tumor cells.
Methods: Five samples of PCP were utilized for single-cell RNA sequencing. The most relevant ligand and receptor interactions among different cells were calculated using the CellChat package in R software.
