Patient Data

CT angiography

CTA demonstrates bilateral supraclinoid ICA occlusion with large bilateral lenticulostriate collaterals. 

Case Discussion

It is important to remember that Moya-moya pattern is seen in a variety of contexts. Moya moya disease is, in contrast, idiopathic and seen primarily in children. When complications arise they can be fairly well predicted by the patient's age. Children typically suffer from ischaemic events, whereas adults tend to present with haemorrhages from the lenticulostriate collateral vessels.
