Primary Meningeal Pleomorphic Xanthoastrocytoma With Anaplastic Features: A Report of 2 Cases, One With BRAF(V600E) Mutation and Clinical Response to the BRAF Inhibitor Dabrafenib [PDF]

, 2015
Primary meningeal gliomas are rare tumors composed of a heterogeneous group of neoplasms. We present 2 clinically aggressive cases of primary meningeal pleomorphic xanthoastrocytoma that clinically mimicked meningioma. One case presented in the posterior

Cerebral anaplastic pleomorphic xanthoastrocytoma with meningeal dissemination at first presentation.

, 2004
INTRODUCTION: Pleomorphic xanthoastrocytoma (PXA) is a rare brain glial tumour found in young patients. Most cases are reported as evolving low-grade neoplasms associated with a long survival after complete surgical resection.

Consensus guidelines for the management of primary supra-tentorial intraventricular tumour for low- and middle-income countries

Journal of the Pakistan Medical Association
Almost any primary or metastatic brain tumour can manifest in intraventricular (IV) locations. These tumours may either originate within the ventricular system or extend into the IV space through growth.

Cytologically Proven Meningeal Carcinomatosis in Patients with Lung Cancer: Clinical Observation of 34 Cases

Journal of the Formosan Medical Association, 2008
Meningeal carcinomatosis (MC) is a rare neurologic complication of lung cancer. Occasionally, it is the initial presentation of lung cancer. The clinical features of MC exclusively in lung cancer patients have not been well identified and characterized ...

Contrast enhanced imaging features of liver metastasis from a meningeal solitary fibrous tumor: a case report

, 2018
A solitary fibrous tumor seldom originates from the meninges, and the accuracy of imaging modalities in the diagnosis of meningeal SFT metastasisis is perlexing.

Ofatumumab Therapy and Long‐Term Seizure Outcomes of Patients With Relapsing Anti‐NMDA Receptor Encephalitis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective There is a lack of studies on seizure outcomes associated with ofatumumab therapy in patients for relapsing anti‐N‐methyl‐D‐aspartate (NMDA) receptor encephalitis. We aimed to evaluate long‐term seizure outcomes of ofatumumab therapy for relapsing anti‐NMDA receptor encephalitis.

Primary extraosseous dural chondrosarcoma: a case report

BMC Neurology, 2021
Background Dural chondrosarcoma is a very rare intracranial tumor, given that meninges do not normally contain cartilaginous tissue from which it can originate. We present a case of primary extraosseous dural chondrosarcoma.

Disrupted TFEB/GDNF–cAMP/ATP Coupling Underlies Astrocytic Dysfunction and Depression in LRRK2 G2019S Parkinson's Mice

Advanced Science, EarlyView.
ABSTRACT The LRRK2 G2019S mutation, a Parkinson's disease–linked variant, has been associated with depression‐like phenotypes, but mechanisms remain unclear. We chart age‐dependent behavioral changes and astrocyte reactivity in G2019S mice and define a pathway connecting LRRK2 to TFEB/GDNF signaling, cellular energetics, and inflammation.

Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

Advanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.
