Postinterventional MRI two days after symptom onset and stent placement shows no territorial infarction, tissue oedema or intracranial haemorrhage.
There are small cortical areas of restricted diffusion in the right MCA territory (bright spots in the b1000 diffusion weighted image). These are very probably localizations of microembolism due to the ICA dissection or due to the interventional procedure. These lesions were clinically asymptomatic.
