Medulloblastoma

Case contributed by Dr Anthony Nuñez

Presentation

Patient with a posterior fossa tumour that caused obstructive hydrocephalus. Actually with a ventricular catheter. MRI ordered to characterize the posterior fossa mass.

Patient Data

Age: 10 years
Gender: Male
MRI

Occupying the 4th ventricle, there is a solid mass that seems to arise from the cerebellar vermis, with low signal on T1, high signal on T2 and FLAIR, and patchy contrast enhancement. It also presents with high signal on DWI. 

Case Discussion

Medulloblastoma is the most common malignant tumor in childhood. Usually, it produces hydrocephalus, as in this case that the patient required the ventricular shunt due to the obstructive process.  

Findings were consistent with a medulloblastoma (confirmed on histology).
