Presentation
A young female presenting with progressive headaches and decreased level of consciousness.
Patient Data
The imaging provided shows a large mass obliterating and expanding the fourth ventricle, with upstream changes of acute obstructive hydrocephalus that includes ventriculomegaly and transependymal CSF flow.
Case Discussion
Pathology report showed medulloblastoma.
This case shows the typical presentation and MRI imaging findings seen with medulloblastoma.
As the probability of leptomeningeal / CSF seeding is considerable with medulloblastoma, further imaging of the neuraxis was performed and showed no drop metastasis.
