American Roentgen Ray Society Images of Medulloblastoma MRI
Brain MRI with gadolinium based contrast is the investigation of choice for the diagnosis of medulloblastoma. On a T1 weighted brain MRI image, medulloblastoma is characterized by a hypointense mass located at the posterior cerebral fossa that may demonstrate calcification and necrosis.
- Brain MRI with gadolinium based contrast is the investigation of choice for the diagnosis of medulloblastoma.
- On brain MRI, medulloblastoma is characterized by a mass located at the posterior cerebral fossa.
- MRI image characteristics observed among medulloblastoma patients include:
- T1 weighted image demonstrates:
- Hypointense mass
- T1 weighted image with gadolinium contrast demonstrates:
- Heterogeneous enhancement in 90% of the cases
- T2 weighted image demonstrates:
- FLAIR MRI image demonstrates:
- Localized areas of isointensity or hypointensity
- Radiating star-shaped enhancement
- Multiple nodular enhancing pattern
- Gadolinium based contrast MRI imaging of the whole central nervous system is recommended to identify any drop metastases and leptomeningeal seeding.
