Overview
- Gangliogliomas share imaging features with other low-grade neoplasms.
- Calcification is a common finding.
- Usually little or no associated mass effect or evidence of surrounding vasogenic edema.
- Gangliogliomas have variable manifestations at nonenhanced CT and hypoattenuating mass is the most frequent manifestation.
- Remodeling of the skull may be seen if the neoplasm is located within the peripheral brain.
- MRI appearance of gangliogliomas is also variable and nonspecific.
- In general, the lesions are hypointense to isointense relative to gray matter on T1 weighted images and hyperintense relative to gray matter on T2 weighted images.
- The frequency of enhancement following intravenous administration of iodinated contrast media is variable (16%–80%) of gangliogliomas.
