A 13-year-old, male neutered, Domestic Shorthair cat presented to the Virginia Tech Veterinary Teaching Hospital Neurology service for evaluation of episodes of altered mental status. On initial evaluation, the patient was noted to be alert and responsive, with a vestibular ataxia characterized by falling to the left and circling to the right. The neuroanatomic localization was consistent with multifocal intracranial disease affecting both brainstem and forebrain structures.

Background: Radiogenomics, the intersection of imaging and genetics, is important in improving glioma diagnosis and treatment. This study aims to correlate imaging features with isocitrate dehydrogenase (IDH) mutation status, providing a non-invasive diagnostic tool to identify the genetic background of gliomas.
Methods: In a retrospective sample of 59 patients with either IDH wild-type (WT) or IDH mutant gliomas, the study employed volumetric and morphologic magnetic resonance imaging (MRI) analyses to discern molecular alterations based on radiographic signatures.

Primary intradural extramedullary Ewing sarcoma (PIEES) is a very rare and aggressive tumor with poorly recognized radiological features. In this case series, we present our institutional experience with PIEES with emphasis on imaging and temporal evolution of the disease. In total, 8 patients with pathological diagnosis of PIEES were included in this study.
