Striking a Chord? Not a Typical Low-Grade Glioma

A 48-year-old male presented with worsening gait instability, blurry vision, headache, and intermittent emesis over a 4-month period. Magnetic resonance imaging of the brain demonstrated a right ventricular mass at the foramen of Monro with associated obstructive hydrocephalus (Fig 1). The lesion was well circumscribed and nonenhancing and measured 1.9 cm × 1.9 cm × 2.1 cm with minimal surrounding edema. A computed tomography scan of the chest/abdomen/pelvis showed no evidence of extracranial disease.

CONCLUSIONS: Immunohistochemistry seems to be a promising option not only in clinical recognition, but also in the selection and monitoring of treatment effects. However, these methods have not yet recommended for routine clinical use. PMID: 33032462 [PubMed - as supplied by publisher]

Authors: Kim EH, Shim WH, Lee JS, Yoon HM, Ko TS, Yum MS Abstract BACKGROUND AND PURPOSE: Recent quantitative neuroimaging studies of childhood absence epilepsy (CAE) have identified various structural abnormalities that might be involved in the onset of absence seizure and associated cognitive and behavioral functions. However, the neuroanatomical alterations specific to CAE remain unclear, and so this study investigated the regional alterations of brain structures associated with newly diagnosed CAE. METHODS: Surface and volumetric magnetic resonance imaging data of patients with newly diagnosed CAE (n=18) an...

CONCLUSIONS: Paramagnetic rims might be a characteristic MRI finding for MS, and therefore they have potential as an imaging marker for differentially diagnosing MS from NMOSD using 3-T MRI. PMID: 33029961 [PubMed]

We present a case of a 42-year-old male patient presenting with headache and vomiting. Imaging demonstrated obstructive hydrocephalus and a ring-enhancing lesion in the right posterior thalamus. After endoscopic third ventriculostomy and stereotactic biopsy, the histopathologic diagnosis of a malignant glioma was confirmed by DNA methylation array as GBM isocitrate dehydrogenase wild type. The patient was treated with combined treatment of chemoradiation with temozolomide (TMZ) including proton boost, TMZ maintenance, and tumor-treating fields. In this case report, complete radiological response was observed 1 year after t...

J Neurol Surg B DOI: 10.1055/s-0038-1625967Suprasellar tumors in particular tumors located in the retrochiasmatic area and anterior third ventricle are challenging cases in terms of optimal surgical exposure. Several approaches have been described including transsylvian, translamina terminalis, endoscopic endonasal, and anterior interhemispheric. Each approach has advantages and disadvantages. In this video, we present a case of retrochiasmatic anterior third ventricular tumor that was operated via anterior interhemispheric transcallosal transforaminal approach. The patient is a 42-year-old female who presented with sudden...

We present and discuss a case of chordoid glioma that arose in a 46-year-old female who presented with progressive fatigue, headache, and altered mental status, attributable to severe hydrocephalus caused by a third ventricular mass. She underwent urgent subtotal resection and ventriculo-peritoneal shunt placements. Post-operative MRI noted residual tumor in the anterior resection cavity. An MRI performed 9 weeks later showed substantial progression, with marked tumor enlargement and compression of adjacent hypothalamic structures and the optic chiasm. Despite a course of radiation therapy, the tumor continued to enlarge, ...

CONCLUSION:To the best of our knowledge, there are 8 prior reported cases of pineal region PXA with such lesions rarely occurring in individuals with NF1. These masses present similarly to dysplastic tumor types, and should be considered as a rare etiology of NF1 associated tectal masses.
