Background: Late brain metastasis from renal cell carcinoma (RCC), which is generally considered as metastasis occurring more than 10 years after nephrectomy, often occurs as a solitary lesion, and total resection is recommended to achieve remission.
Case Description: We describe a rare case of multiple late brain metastases from RCC in a 60-year-old man who presented with 3 brain metastases from RCC 22 years after nephrectomy. Total removal of the 3 lesions achieved remission without adjuvant therapy.
Conclusions: Total removal of late brain metastasis from RCC, even occurring with multiple lesions, can achieve total remission under specific conditions.

Background: Recent years have seen persistently poor prognoses for glioma patients. Therefore, exploring the molecular subtyping of gliomas, identifying novel prognostic biomarkers, and understanding the characteristics of their immune microenvironments are crucial for improving treatment strategies and patient outcomes.
Methods: We integrated glioma datasets from multiple sources, employing Non-negative Matrix Factorization (NMF) to cluster samples and filter for differentially expressed metabolic genes.

Introduction: and research question: Prognostic factors to predict the behavior of pituitary neuroendocrine tumors (PitNET) are scarce. PD-L1 expression was associated with prognosis in other neuroendocrine neoplasms and we analyzed PD-L1 expression in PitNET, according to the 2022 WHO classification.
Material And Methods: A retrospective analysis was performed.

Background: Glioblastoma multiforme (GBM) is the most prevalent primary brain tumour, with an incidence of 2 per 100,000. The standard clinical treatments do not sufficiently target cell migration and invasion, leading to recurrence after surgical resection and resistance after chemotherapy and radiotherapy. Pre-clinical studies are being conducted to construct artificial substrates that can mimic the tumour microenvironment (TME) to prevent GBM cells from migrating along their primary route through blood vessels and white matter tracts.

Hemodynamic measurements such as cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) can provide useful information for the diagnosis and characterization of brain tumors. Previous work showed that arterial spin labeling (ASL) in combination with vasoactive stimulation enabled simultaneous non-invasive evaluation of both parameters, however this approach had not been previously tested in tumors. The aim of this work was to investigate the application of this technique, using a pseudo-continuous ASL (PCASL) sequence combined with breath-holding at 3 T, to measure CBF and CVR in high-grade gliomas and metastatic lesions, and to explore differences across tumoral-peritumoral regions and tumor types.

Purpose: While glioblastoma is the most common malignant brain tumor in adults, extracerebral manifestations are very rare in this highly aggressive disease with poor prognosis.
Methods: We conducted a systematic literature review in the PubMed database and complemented the data by inclusion of a case treated in our clinic. In this context, we report on a 60-year-old woman with a right frontal glioblastoma, IDH wildtype, MGMT methylated.
