Medulloblastoma

Case contributed by Dr Mahomed A. Osman

Presentation

3 weeks of headache, nausea & vomiting

Patient Data

Age: 20
Gender: Male
Modality: MRI

4 x 5 cm homogeneous enhancing intra-axial lesion L cerebellum, showing restricted diffusion, heterogenous signal on T2 weighted sequences, hypointense to grey matter on T1 weight sequences and hyper intense to grey matter on FLAIR sequences.

Case Discussion

The tumour was resected and histologically confirmed to be medulloblastoma. 

Medulloblastoma is typically a paediatric tumour that most commonly arises from the vermis. When seen in adults, however, they are more likely to arise in atypical locations such as the lateral cerebellar hemispheres as opposed to the vermis, which is consistent with the findings in this particular case.
