Extraneural metastases from primary intracranial tumours are extremely rare. We present a case of metastatic oligodendroglioma causing extradural spinal cord compression at the level of the sixth thoracic vertebrae resulting in paraplegia. We discuss the routes of tumour dissemination and possible reasons for the rarity of cases of metastatic oligodendroglioma.

Background And Objectives: Oligodendrogliomas are primary brain tumors classified as isocitrate deshydrogenase-mutant and 1p19q codeleted in the 2021 World Health Organization Classification of central nervous system tumors. Surgical resection, radiotherapy, and chemotherapy are well-established management options for these tumors. Few studies have evaluated the efficacy of stereotactic radiosurgery (SRS) for oligodendroglioma.

Background: Brain calcifications, found in various conditions, may be incidental or crucial for diagnosis. They occur in physiological changes, infections, genetic diseases, neurodegenerative conditions, vascular syndromes, metabolic disorders, endocrine disorders, and primary tumors like oligodendroglioma. While often incidental, their presence can be vital for accurate diagnosis.

Diffuse glioneuronal tumor with oligodendroglioma-like features and nuclear clusters (DGONC) is a rare brain tumor of the central nervous system (CNS). Although only a few cases of DGONC have been reported following the initial description of the tumor, they have a distinct DNA methylation pattern and share a recurrent chromosomal finding of monosomy 14. We encountered a seven-year-old boy who presented with seizures and was found to have a left frontal and suprasellar mass.

Objective: The endoscopic transorbital approach (ETOA) has emerged as a promising minimally invasive technique for resection of lesions in the mediobasal temporal region (MTR) due to its potential to preserve the integrity of the optic radiation (OR). This study evaluated the safety and efficacy of ETOA using an OR-sparing surgical strategy for mediobasal temporal lesions.
Methods: A retrospective review was conducted of the medical records of 15 patients (7 females and 8 males) who underwent ETOA for lesions in the MTR between November 2017 and November 2022.

A 10-year-old female spayed boxer was treated with stereotactic radiotherapy (SRT) for a suspected glioma in the left piriform lobe. The intra-axial lesion was T2 hyperintense, T2 FLAIR hyperintense, T1 hypointense, and did not uptake contrast. Imaging was performed with an MRI every 3 months, and at the 6-month recheck, new lesions in the left hippocampus and right piriform lobe were evident without clinically apparent neurological progression.
