A glioma is a type of brain tumor that arises from glial cells in the brain or spinal cord.
Symptoms depend on where the tumour is and may include headache, seizures, weakness, confusion, speech difficulty, vision problems, or changes in behaviour.
Imaging helps show where the tumour is, how large it is, whether it is causing swelling or pressure, and helps doctors plan biopsy or treatment.
MRI is central to detecting the lesion, showing its extent, and helping plan biopsy, surgery, and follow-up.
Management may include surgery, radiation, chemotherapy, or monitoring depending on tumor type and grade.
