MRI - Non enhanced MRI
- normal appearance of the cerebral hemispheres, corpus callosum, brainstem, and posterior fossa, with preserved gray/white matter differentiation
- no evidence of high signal intensity foci, haemorrhage, infarction, mass, brain oedema or midline shift
- normal ventricular system, basal cisterns, Sylvian fissures and convexity sulci
- the visualised parts of the skull bone show small elliptical-shaped right high parietal scalp haematoma; the visualised sinuses are unremarkable
- the visualised neck and cranial arterial system show the tortuous nature of the visualised extra- and intracranial portion of both the carotid and vertebrobasilar arterial system: affected vessels are forming multiple loops and kinks, best appreciated on the 3D MRA sequences
- there is no evidence of arterial narrowing, dissection, irregularity, aneurysm or occlusion
- NB the patient was found to have aortic arch tortuosity (not shown)
IMPRESSION:
Known case of arterial tortuosity syndrome, showing:
- tortuous nature of the visualized extra- and intracranial portion of both the carotid and the vertebrobasilar system
- no evidence of narrowing, irregularity, aneurysm or occlusion
- unremarkable MRI study of the brain
