Migraine

Case contributed by Dr Jeremy Jones

Presentation

Acute onset right leg weakness and dysphasia.

Patient Data

Age: 7 years
Gender: Female
Modality: MRI

There is no T2 or T1 signal abnormality. No diffusion restriction. Marked asymmetry between the cortical veins demonstrated on the SWI and subtle reduction of arterial supply on the same side. 

Case Discussion

The changes on the MRI reflect reversible vasodilatation of migraine which has been reported1. In addition, there is mild ipsilateral arteriospasm. The vascular changes occur on the contralateral side to the hemiparesis. Speech was affected, suggesting that the main speech centre is left sided in this patient.

No features to suggest stroke and no other cause for symptoms. 

Symptoms resolved over 24 hours with no residual neurological deficit.
